Why Scavio over Tavily?

Scavio is a full Tavily alternative built for multi-platform agents — here is Tavily vs Scavio at a glance:

What Can You Build?

• Shopping agents -- search Amazon and Walmart, compare prices, find deals across 22 marketplaces
• Product research agents -- Google reviews + Amazon listings + YouTube reviews + Reddit opinions in one query
• Content research agents -- YouTube trends + Reddit sentiment + Google news in a single workflow
• Brand monitoring -- track what Reddit and Google say about any topic in real time
• Social media agents -- TikTok, Instagram and X profile analytics, hashtag tracking, post/video comments, and trend discovery
• B2B prospecting agents -- LinkedIn people, companies, posts and job listings for lead research and hiring signals
• Travel and local agents -- Google Flights, Hotels, Maps places and reviews behind one API key

Quick Start

import os
from langchain_scavio import ScavioSearch

os.environ["SCAVIO_API_KEY"] = "sk_live_..."

tool = ScavioSearch()
result = tool.invoke({"query": "best python web frameworks 2026"})

All 96 Tools

Per platform: Google 12, YouTube 16, Instagram 12, Reddit 12, TikTok 11, X 11, LinkedIn 9, TikTok Shop 8, Amazon 3, Walmart 2.

New in 3.3. Reddit goes from 2 tools to all 12 endpoints: search suggestions, post comments, comment replies, subreddit metadata and feed, user profile/posts/comments, the popular feed and trending queries. Every Reddit endpoint costs 1 credit. ScavioRedditSearch and ScavioRedditPost are unchanged apart from their descriptions, which now state the cost -- so every tool in the package states its cost.

New in 3.2. X (11 tools) and LinkedIn (9) are new platforms; Google gained its 11 remaining v2 verticals (AI Mode, Maps place/reviews, Shopping, Flights, Hotels, Trends, Trending) and YouTube its 8 remaining endpoints (Shorts, suggestions, comment replies, related, channel search/shorts/community/resolve). Google tools now take the v2 parameters natively -- gl, hl, start, google_domain -- with country_code, language and page kept as aliases. Every tool description now states its credit cost.

Use with a LangChain Agent

Scavio tools plug into the current create_agent API from langchain.agents:

from langchain.agents import create_agent
from langchain_scavio import (
    ScavioSearch,
    ScavioAmazonSearch, ScavioAmazonProduct,
    ScavioWalmartSearch,
    ScavioYouTubeSearch, ScavioYouTubeVideo, ScavioYouTubeTranscript,
    ScavioRedditSearch, ScavioRedditPost,
    ScavioTikTokSearchVideos, ScavioTikTokProfile, ScavioTikTokVideo,
)

agent = create_agent(
    "openai:gpt-5.5",
    tools=[
        ScavioSearch(max_results=5),
        ScavioAmazonSearch(max_results=5),
        ScavioAmazonProduct(),
        ScavioWalmartSearch(max_results=5),
        ScavioYouTubeSearch(max_results=5),
        ScavioYouTubeVideo(),
        ScavioYouTubeTranscript(),
        ScavioRedditSearch(max_results=5),
        ScavioRedditPost(),
        ScavioTikTokSearchVideos(max_results=5),
        ScavioTikTokProfile(),
        ScavioTikTokVideo(),
    ],
)

response = agent.invoke({
    "messages": [{"role": "user", "content": "Find me a Python book on Amazon under $30"}]
})

Async Support

All tools support async invocation:

result = await tool.ainvoke({"query": "async python frameworks"})

Configuration

Google Search

Every Google tool targets the v2 API (/api/v2/google*) and takes the v2 wire parameters directly: gl, hl, start, google_domain and device. Google v1 was retired on 2026-08-04 and now returns HTTP 410.

start is a 0-based result offset, not a page number: 0 is the first page, 10 the second, 20 the third.

from langchain_scavio import ScavioSearch

tool = ScavioSearch(
    scavio_api_key="sk_live_...",       # or SCAVIO_API_KEY env var
    max_results=5,
    light_request=None,                  # deprecated, ignored (v2 always full, 1 credit)
    include_knowledge_graph=True,
    include_questions=True,
    include_related=False,
    gl="us",                             # native v2 country
    hl="en",                             # native v2 UI language
    search_type="classic",               # classic|news|maps
    device="desktop",
)

result = tool.invoke({"query": "vector databases", "start": 10})  # page 2

country_code, language and page still work as pre-3.2 aliases of gl, hl and start, but the native names win when both are supplied.

Google verticals

Eleven more Google surfaces, 1 credit each. All of them return a flat response -- there is no data wrapper.

from langchain_scavio import (
    ScavioGoogleAIMode,
    ScavioGoogleFlights,
    ScavioGoogleHotels,
    ScavioGoogleHotelsDetail,
    ScavioGoogleMapsPlace,
    ScavioGoogleMapsReviews,
    ScavioGoogleShopping,
    ScavioGoogleShoppingProduct,
    ScavioGoogleShoppingStores,
    ScavioGoogleTrending,
    ScavioGoogleTrends,
)

# AI Mode: a synthesised answer with citations
result = ScavioGoogleAIMode().invoke({"query": "how to cache LLM responses"})
# result["text_blocks"] + result["references"]

# Maps: place details and reviews (search lives on ScavioSearch search_type="maps")
result = ScavioGoogleMapsPlace().invoke({"place_id": "ChIJN1t_tDeuEmsRUsoyG83frY4"})
result = ScavioGoogleMapsReviews(max_results=10).invoke({
    "place_id": "ChIJN1t_tDeuEmsRUsoyG83frY4",
    "sort_by": "newest",                 # relevance|newest|highest_rating|lowest_rating
})

# Shopping: sort_by is a NUMBER here, and start is an offset
result = ScavioGoogleShopping(max_results=10).invoke({
    "query": "mechanical keyboard",
    "max_price": 150,
    "sort_by": 1,                        # 0 relevance, 1 price asc, 2 price desc
    "start": 60,
})
# ... but a STRING enum on the product endpoint
result = ScavioGoogleShoppingProduct().invoke({
    "catalog_id": "1234567890",
    "query": "mechanical keyboard",      # required whenever catalog_id is set
    "sort_by": "total_price",
})
result = ScavioGoogleShoppingStores().invoke({
    "catalog_id": "1234567890",
    "next_page_token": "...",            # from the product response
})

# Travel
result = ScavioGoogleFlights().invoke({
    "departure_id": "JFK",
    "arrival_id": "LHR",
    "outbound_date": "2026-09-01",
    "type": 2,                           # 1 round trip (needs return_date), 2 one way
})
hotels = ScavioGoogleHotels(max_results=10).invoke({
    "query": "Lisbon hotels",
    "check_in_date": "2026-09-01",
    "check_out_date": "2026-09-04",
})
# feed a property's detail_token back in -- and re-send both dates
result = ScavioGoogleHotelsDetail().invoke({
    "detail_token": hotels["properties"][0]["detail_token"],
    "check_in_date": "2026-09-01",
    "check_out_date": "2026-09-04",
})

# Trends uses an UPPERCASE geo, not gl; Trending has no query at all
result = ScavioGoogleTrends().invoke({
    "query": "langchain,llamaindex",     # comma-separate to compare terms
    "geo": "US",
    "date": "today 12-m",
})
result = ScavioGoogleTrending(max_results=10).invoke({"geo": "US", "hours": 24})

Amazon

from langchain_scavio import ScavioAmazonSearch, ScavioAmazonProduct, ScavioAmazonOffers

search = ScavioAmazonSearch(max_results=5)
search.invoke({"query": "wireless headphones", "country": "us", "page": 1})

product = ScavioAmazonProduct()
product.invoke({"query": "B08N5WRWNW"})           # query = ASIN

offers = ScavioAmazonOffers()
offers.invoke({"query": "B08N5WRWNW"})            # every seller for that ASIN

Targeting a marketplace: country takes a two-letter code, not a domain. Supported: us (default), gb (the UK is gb, not uk), ca, de, fr, es, it, jp, in, au, br, mx, nl, pl, se, sg, ae, sa, eg, cn, be, tr. An unrecognised code falls back to us.

Amazon changed in 3.0 (breaking). The upstream provider moved and the request surface shrank. sort_by, pages, category_id, merchant_id, language, currency, device, zip_code and autoselect_variant are gone from all Amazon tools -- the marketplace ignores every one of them, so they are removed rather than kept as silent no-ops (sort_by was verified: all six sort values return the identical unordered set). domain and start_page still work on the wire and are still forwarded, but they are no longer in the tool schemas: use country and page. Response fields were renamed too -- url_image is now image, best_seller/is_amazons_choice collapsed into badge, and buybox is gone (use ScavioAmazonOffers).

Walmart

from langchain_scavio import ScavioWalmartSearch, ScavioWalmartProduct

search = ScavioWalmartSearch(max_results=5)
result = search.invoke({
    "query": "air fryer",
    "sort_by": "price_low",              # best_match|price_low|price_high|best_seller
    "max_price": 5000,                   # in cents
    "fulfillment_speed": "2_days",       # today|tomorrow|2_days|anytime
})

product = ScavioWalmartProduct()
result = product.invoke({"product_id": "123456789"})

YouTube

from langchain_scavio import (
    ScavioYouTubeSearch, ScavioYouTubeVideo, ScavioYouTubeComments,
    ScavioYouTubeTranscript, ScavioYouTubeChannel,
    ScavioYouTubeChannelVideos, ScavioYouTubeStreams,
)

# Video search (2 credits per call)
search = ScavioYouTubeSearch(max_results=5)
result = search.invoke({
    "query": "python tutorial",
    "duration": "medium",                # short|medium|long
    "upload_date": "this_month",         # last_hour|today|this_week|this_month|this_year
    "sort_by": "view_count",             # relevance|date|view_count|rating
    "video_type": "video",               # video|channel|playlist
    "features": ["hd", "subtitles"],     # hd|4k|subtitles|creative_commons|live|360|3d|hdr|vr180
})

# Paginate with the previous response's next_cursor
next_page = search.invoke({
    "query": "python tutorial",
    "cursor": result["data"]["next_cursor"],
})

# Full video details (chapters, captions, keywords)
video = ScavioYouTubeVideo()
result = video.invoke({"video_id": "dQw4w9WgXcQ"})  # video ID or watch URL

# Comments (paginate via data.next_cursor)
comments = ScavioYouTubeComments(max_results=10)
result = comments.invoke({"video_id": "dQw4w9WgXcQ"})

# Transcript as plain text or timed SRT (8 credits per call)
transcript = ScavioYouTubeTranscript()
result = transcript.invoke({"video_id": "dQw4w9WgXcQ", "format": "text"})

# Channel details and uploads
channel = ScavioYouTubeChannel()
result = channel.invoke({"channel_id": "@YouTube"})  # ID, @handle, or URL

channel_videos = ScavioYouTubeChannelVideos(max_results=5)
result = channel_videos.invoke({"channel_id": "UC_x5XG1OV2P6uZZ5FSM9Ttw"})

# Playable/downloadable stream URLs (3 credits per call)
streams = ScavioYouTubeStreams()
result = streams.invoke({"video_id": "dQw4w9WgXcQ"})

# ScavioYouTubeMetadata is a deprecated alias of ScavioYouTubeVideo

The other eight YouTube endpoints:

from langchain_scavio import (
    ScavioYouTubeChannelCommunity, ScavioYouTubeChannelResolve,
    ScavioYouTubeChannelSearch, ScavioYouTubeChannelShorts,
    ScavioYouTubeCommentReplies, ScavioYouTubeRelated,
    ScavioYouTubeShorts, ScavioYouTubeSuggestions,
)

# Shorts search (2 credits per call)
result = ScavioYouTubeShorts(max_results=10).invoke({"query": "funny cats"})

# Keyword expansion before you spend a search
result = ScavioYouTubeSuggestions().invoke({"query": "python tut", "region": "US"})

# Replies need BOTH the video id and a comment's reply_cursor
comments = ScavioYouTubeComments().invoke({"video_id": "dQw4w9WgXcQ"})
result = ScavioYouTubeCommentReplies().invoke({
    "video_id": "dQw4w9WgXcQ",
    "reply_cursor": comments["data"]["comments"][0]["reply_cursor"],
})

# Related videos -- note: no next_cursor on this endpoint
result = ScavioYouTubeRelated(max_results=10).invoke({"video_id": "dQw4w9WgXcQ"})

# Find a channel, then reuse its UC id everywhere else
result = ScavioYouTubeChannelSearch(max_results=5).invoke({"query": "mrbeast"})
resolved = ScavioYouTubeChannelResolve().invoke({"channel": "@MrBeast"})
channel_id = resolved["data"]["channel_id"]

result = ScavioYouTubeChannelShorts(max_results=10).invoke({"channel_id": channel_id})
# community posts land under data.posts, not data.results
result = ScavioYouTubeChannelCommunity(max_results=10).invoke({
    "channel_id": channel_id,
})

Reddit

All 12 Reddit endpoints cost 1 credit each.

from langchain_scavio import (
    ScavioRedditSearch, ScavioRedditSearchSuggestions,
    ScavioRedditPost, ScavioRedditPostComments, ScavioRedditCommentReplies,
    ScavioRedditSubreddit, ScavioRedditSubredditPosts,
    ScavioRedditUser, ScavioRedditUserPosts, ScavioRedditUserComments,
    ScavioRedditPopular, ScavioRedditTrending,
)

search = ScavioRedditSearch(max_results=5)
result = search.invoke({"query": "langchain"})
# result["data"]["results"] + next_cursor + has_more
# Relevance order only: the endpoint has no sort or result-type filter

# Paginate by passing back the previous response's next_cursor
next_page = search.invoke({
    "query": "langchain",
    "cursor": result["data"]["next_cursor"],
})

# Expand a query before searching
ScavioRedditSearchSuggestions().invoke({"query": "langchain"})
# result["data"]["suggestions"] is a list of strings + total_count

post = ScavioRedditPost()
result = post.invoke({
    "url": "https://www.reddit.com/r/programming/comments/abc123/example_post/"
})
# result["data"] is a flat post object (post_id, title, text, score,
# upvote_ratio, num_comments, media). It does NOT return comments.

Comments are a separate endpoint, and replies are a separate endpoint again:

comments = ScavioRedditPostComments(max_results=10).invoke({
    "post_id": result["data"]["post_id"],   # 't3_...', a bare id, or a post URL
    "sort": "TOP",                          # UPPERCASE; default TOP
})
# comments["data"]["comments"] -> comment_id, text, author, score, created_at,
# depth, reply_cursor

# To expand one comment's thread, pass THAT comment's reply_cursor -- a
# next_cursor will not work here, and cursor is required.
ScavioRedditCommentReplies().invoke({
    "post_id": result["data"]["post_id"],
    "cursor": comments["data"]["comments"][0]["reply_cursor"],
})
# -> data.replies, same comment shape

Subreddits, redditors and the site-wide feeds:

ScavioRedditSubreddit().invoke({"subreddit": "programming"})
# flat data: subscribers, active_count, description, icon, banner, is_nsfw

ScavioRedditSubredditPosts(max_results=10).invoke({
    "subreddit": "programming",
    "sort": "RISING",   # BEST|HOT|NEW|TOP|CONTROVERSIAL|RISING, default HOT
})
# data.posts -- this feed shape has no body text, thumbnail or is_nsfw;
# fetch a post_id through ScavioRedditPost for the full body

ScavioRedditUser().invoke({"username": "spez"})          # flat profile + karma
ScavioRedditUserPosts().invoke({"username": "spez", "sort": "TOP"})     # data.posts
ScavioRedditUserComments().invoke({"username": "spez"})  # data.comments

ScavioRedditPopular().invoke({})     # r/popular; cursor is its only parameter
ScavioRedditTrending().invoke({})    # data.trending -> {query, raw_query}

Sort values are UPPERCASE and differ by endpoint: RISING is accepted only by ScavioRedditSubredditPosts, and the server default is TOP for comments, HOT for the subreddit feed and NEW for the user feeds.

TikTok

from langchain_scavio import (
    ScavioTikTokProfile, ScavioTikTokUserPosts, ScavioTikTokVideo,
    ScavioTikTokVideoComments, ScavioTikTokCommentReplies,
    ScavioTikTokSearchVideos, ScavioTikTokSearchUsers,
    ScavioTikTokHashtag, ScavioTikTokHashtagVideos,
    ScavioTikTokUserFollowers, ScavioTikTokUserFollowings,
)

# Look up a user profile (returns sec_uid needed by other tools)
profile = ScavioTikTokProfile()
result = profile.invoke({"username": "tiktok"})
sec_uid = result["data"]["user"]["sec_uid"]

# Fetch their recent posts
posts = ScavioTikTokUserPosts(max_results=5)
result = posts.invoke({"sec_user_id": sec_uid, "sort_type": "1"})  # popular

# Search videos by keyword
search = ScavioTikTokSearchVideos(max_results=5)
result = search.invoke({
    "keyword": "python tutorial",
    "sort_type": "1",                        # 0=relevance, 1=most likes
    "publish_time": "30",                    # 0=all, 1=day, 7=week, 30=month
})

# Get video details and comments
video = ScavioTikTokVideo()
result = video.invoke({"video_id": "7123456789012345678"})

comments = ScavioTikTokVideoComments(max_results=10)
result = comments.invoke({"video_id": "7123456789012345678"})

# Hashtag research
hashtag = ScavioTikTokHashtag()
result = hashtag.invoke({"hashtag_name": "python"})
hashtag_id = result["data"]["challengeInfo"]["challenge"]["id"]

hashtag_videos = ScavioTikTokHashtagVideos(max_results=5)
result = hashtag_videos.invoke({"hashtag_id": hashtag_id})

TikTok Shop

Eight tools over the TikTok Shop catalog. Two things to know before you wire them together:

1. ScavioTikTokShopProduct resolves only about 44% of the product ids that ScavioTikTokShopSearch returns. Upstream has no detail data for the rest, so a not-found result is a normal outcome rather than an error -- skip the product instead of retrying. Search is a listing source, not the first leg of a reliable search-then-detail pipeline.
2. ScavioTikTokShopProduct does not return a price. Upstream masks the digits on the product page, so price.current and price.original come back null. Exact prices are on ScavioTikTokShopSearch, ScavioTikTokShopShopProducts and ScavioTikTokShopCategoryProducts.

from langchain_scavio import (
    ScavioTikTokShopSearch, ScavioTikTokShopSearchSuggestions,
    ScavioTikTokShopProduct, ScavioTikTokShopProductReviews,
    ScavioTikTokShopCategories, ScavioTikTokShopCategoryProducts,
    ScavioTikTokShopShopProducts, ScavioTikTokShopResolve,
)

# Search the US catalog -- this is where exact prices live
search = ScavioTikTokShopSearch(max_results=10)
result = search.invoke({"search": "phone case"})
for product in result["data"]["products"]:
    print(product["title"], product["price"]["current"], product["rating"]["score"])

# Paginate with the opaque cursor; dedupe by product_id across pages
if result["data"]["has_more"]:
    page2 = search.invoke({
        "search": "phone case",
        "cursor": result["data"]["next_cursor"],
    })

# Product detail: rich, but priceless (literally) and only ~44% resolvable
detail = ScavioTikTokShopProduct()
result = detail.invoke({"product_id": "1732293553906094315"})
if result.get("not_found"):
    pass                                     # normal: skip it, do not retry
else:
    result["data"]["variants"]               # stock per SKU
    result["data"]["shop"]["followers_count"]

# Reviews: page with has_more, never with total_reviews (it drifts)
reviews = ScavioTikTokShopProductReviews(max_results=20)
result = reviews.invoke({
    "product_id": "1732293553906094315",
    "page_size": 100,
    "sort": "relevant",                      # "recent" is fresher but text-sparse
    "has_media": True,
})

# Category browse (US and GB only)
categories = ScavioTikTokShopCategories()
tree = categories.invoke({})
category_id = tree["data"]["categories"][0]["category_id"]

listing = ScavioTikTokShopCategoryProducts(max_results=10)
result = listing.invoke({"category_id": category_id})

# A seller's whole catalog, with exact prices
shop = ScavioTikTokShopShopProducts(max_results=10)
result = shop.invoke({"shop_id": "7495514739648989419"})

# Turn any share link into an id
resolve = ScavioTikTokShopResolve()
result = resolve.invoke({"url": "https://vt.tiktok.com/ZT2AHoGsE/"})
result["data"]["product_id"], result["data"]["type"]

# Keyword expansion, the only endpoint with genuine 8-region coverage
suggestions = ScavioTikTokShopSearchSuggestions()
result = suggestions.invoke({"search": "wireless", "region": "GB"})
result["data"]["suggestions"]                # plain strings, no volume or score

Instagram

Instagram is priced per endpoint, not flat: 10 credits by default, 8 for ScavioInstagramPost and ScavioInstagramCommentReplies, and 2 for ScavioInstagramUserPosts.

from langchain_scavio import (
    ScavioInstagramProfile, ScavioInstagramUserPosts, ScavioInstagramUserReels,
    ScavioInstagramTaggedPosts, ScavioInstagramStories,
    ScavioInstagramPost, ScavioInstagramPostComments,
    ScavioInstagramCommentReplies, ScavioInstagramSearchUsers,
    ScavioInstagramSearchHashtags,
    ScavioInstagramUserFollowers, ScavioInstagramUserFollowings,
)

# Look up a user profile (returns user_id usable by other tools)
profile = ScavioInstagramProfile()
result = profile.invoke({"username": "instagram"})
user_id = result["data"]["user"]["id"]

# Fetch their recent posts and reels
posts = ScavioInstagramUserPosts(max_results=5)
result = posts.invoke({"username": "instagram"})

reels = ScavioInstagramUserReels(max_results=5)
result = reels.invoke({"username": "instagram"})

# Get a single post's details and comments
post = ScavioInstagramPost()
result = post.invoke({"shortcode": "C1a2b3c4d5e"})

comments = ScavioInstagramPostComments(max_results=10)
result = comments.invoke({
    "shortcode": "C1a2b3c4d5e",
    "sort_order": "newest",                  # popular (default) or newest
})

# Search users and hashtags
search_users = ScavioInstagramSearchUsers(max_results=5)
result = search_users.invoke({"keyword": "cooking"})

search_hashtags = ScavioInstagramSearchHashtags(max_results=5)
result = search_hashtags.invoke({"keyword": "travel"})

X (Twitter)

Eleven endpoints, 1 credit each. The search field is literally search, and handles are passed without the leading @.

from langchain_scavio import (
    ScavioXSearch,
    ScavioXTrending,
    ScavioXTweetComments,
    ScavioXUser,
    ScavioXUserFollowings,
    ScavioXUserTweets,
)

# Search tweets -- the field is `search`, not `query`
search = ScavioXSearch(max_results=10)
result = search.invoke({
    "search": "langchain",
    "search_type": "Latest",              # Top (default), Latest, People, Photos, Videos
})
# result["data"]["timeline"] + next_cursor + has_more

# Profile and timeline
result = ScavioXUser().invoke({"screen_name": "elonmusk"})
result = ScavioXUserTweets().invoke({"screen_name": "elonmusk"})
# user timelines return data.timeline + data.pinned + data.user (no has_more)

# Replies to a tweet, ranked or chronological
result = ScavioXTweetComments().invoke({
    "tweet_id": "1808168603721650364",
    "rank": "latest",                     # lowercase, unlike search_type
})

# Followings come back under data.following -- singular, not "followings"
result = ScavioXUserFollowings().invoke({"screen_name": "elonmusk"})

# Trending takes a country NAME, not an ISO code
result = ScavioXTrending().invoke({"country": "UnitedStates"})

LinkedIn

Nine live endpoints across three credit tiers: profile and single-post reads cost 1, paginated list endpoints cost 10 per page, and job detail costs 30.

from langchain_scavio import (
    ScavioLinkedInCompany,
    ScavioLinkedInJob,
    ScavioLinkedInPersonPosts,
    ScavioLinkedInPostComments,
    ScavioLinkedInSearchJobs,
)

# Profiles are addressed by vanity handle or full URL
result = ScavioLinkedInCompany().invoke({"company": "microsoft"})
# data.featured_employees is a 4-6 person sample -- the employee directory
# endpoint was retired upstream and is not exposed by this package

# Post feeds: 50 per page, 10 credits per page
posts = ScavioLinkedInPersonPosts(max_results=10)
result = posts.invoke({
    "username": "williamhgates",
    "type": "posts",                      # posts (default), comments, reactions
})

# Job search rotates its result set between calls -- dedupe by job id
jobs = ScavioLinkedInSearchJobs(max_results=10)
result = jobs.invoke({"search": "software engineer", "location": "London"})

# Job detail is the most expensive endpoint in the API (30 credits)
result = ScavioLinkedInJob().invoke({"job_id": "4415427228"})

# Post comments page by a 1-based number, not a cursor
result = ScavioLinkedInPostComments().invoke({
    "post_id": "7488618410256523265",
    "page": 1,
})

Five LinkedIn endpoints (person/contact, company/people, company/jobs, search/people, search/posts) were retired upstream and always return HTTP 410. They are deliberately not exposed as tools: an agent calling them would only burn a turn. Use ScavioLinkedInCompany (featured_employees) and ScavioLinkedInSearchJobs with the company name instead.

Credit Costs

Most endpoints cost 1 credit. The exceptions:

Every tool states its own cost in its description, so an agent can see the price before it calls.

Agent-Controllable Parameters

ScavioSearch

ScavioAmazonSearch

There is no sort, category, merchant or price filter: the marketplace ignores them. Rank results yourself.

ScavioAmazonProduct / ScavioAmazonOffers

ScavioWalmartSearch

ScavioYouTubeSearch

ScavioYouTubeVideo / ScavioYouTubeMetadata

ScavioYouTubeComments

ScavioYouTubeTranscript

ScavioYouTubeChannel

ScavioYouTubeChannelVideos

ScavioRedditSearch

Results come back in relevance order. There is no sort or result-type parameter: the endpoint accepts only query and cursor.

ScavioRedditSearchSuggestions

ScavioRedditPost

ScavioRedditPostComments

ScavioRedditCommentReplies

cursor is the one place a next_cursor is not accepted: it must be the reply_cursor carried by a comment from ScavioRedditPostComments.

ScavioRedditSubreddit

ScavioRedditSubredditPosts

This is the only Reddit endpoint that accepts RISING.

ScavioRedditUser

ScavioRedditUserPosts

ScavioRedditUserComments

ScavioRedditPopular

cursor is the endpoint's only parameter: no sort, no subreddit filter.

Error Handling

• Empty results raise ToolException with actionable suggestions for the LLM
• API errors return {"error": "message"} without crashing the agent
• handle_tool_error=True ensures LangChain passes errors to the LLM as context

Architecture

One BaseTool subclass per endpoint, each backed by an APIWrapper that owns a single URL. 96 tools over 97 endpoints (ScavioSearch covers three Google surfaces via search_type; ScavioYouTubeMetadata is a deprecated alias of ScavioYouTubeVideo).

ScavioBaseAPIWrapper                    # Auth, headers, rate limit, sync/async POST
  |
  +-- Google      12 tools -> /api/v2/google*        (14 endpoints)
  +-- YouTube     16 tools -> /api/v1/youtube/*      (15 endpoints)
  +-- Instagram   12 tools -> /api/v1/instagram/*
  +-- Reddit      12 tools -> /api/v1/reddit/*
  +-- TikTok      11 tools -> /api/v1/tiktok/*
  +-- X           11 tools -> /api/v1/x/*
  +-- LinkedIn     9 tools -> /api/v1/linkedin/*     (9 live; 5 retired, not exposed)
  +-- TikTok Shop  8 tools -> /api/v1/tiktok-shop/*
  +-- Amazon       3 tools -> /api/v1/amazon/*
  +-- Walmart      2 tools -> /api/v1/walmart/*

Source layout: scavio_search.py (Google), scavio_youtube.py, scavio_instagram.py, scavio_tiktok.py, scavio_tiktok_shop.py, scavio_x.py, scavio_linkedin.py, scavio_amazon.py, scavio_walmart.py, scavio_reddit.py, with every wrapper in _utilities.py.

Each tool splits parameters into init-only (developer-controlled, e.g. max_results, domain) and LLM-controllable (passed via args_schema at invocation time, e.g. query, sort_by).

Migrating from Tavily

- from langchain_tavily import TavilySearch
+ from langchain_scavio import ScavioSearch

- tool = TavilySearch(max_results=5)
+ tool = ScavioSearch(max_results=5)
