ScrapeUnblocker Python client

Official Python client for the ScrapeUnblocker web scraping API.

Every request is fully JavaScript-rendered in a real browser and routed through premium proxies, so it bypasses Cloudflare, DataDome, PerimeterX, Akamai, Kasada and similar anti-bot systems - from one simple call. You are only billed for successful requests.

• Highest success rate on the market (95%+ on live production traffic)
• Rendered HTML or parsed JSON - no per-site parsers to maintain
• Sync and async clients, fully type-hinted

Install

pip install scrapeunblocker

Requires Python 3.8+.

Quickstart

from scrapeunblocker import Client

su = Client(api_key="YOUR_API_KEY")   # or set the SCRAPEUNBLOCKER_KEY env var

# Rendered HTML for any URL
html = su.get_page_source("https://example.com")

# Structured JSON instead of HTML (products, listings, search results, ...)
product = su.get_parsed("https://www.amazon.com/dp/B08N5WRWNW")
print(product.page_type)   # "product"
print(product.data)        # {...}

Get your API key at app.scrapeunblocker.com. The free trial does not require a credit card.

Authentication

Pass the key directly, or set an environment variable and omit it:

export SCRAPEUNBLOCKER_KEY="YOUR_API_KEY"

from scrapeunblocker import Client
su = Client()   # reads SCRAPEUNBLOCKER_KEY

Fetch rendered HTML

html = su.get_page_source(
    "https://www.nordstrom.com/browse/women/clothing/dresses",
    proxy_country="US",     # route through a specific country
    time_sleep=3,           # wait extra seconds after load
)

Get parsed JSON

Pass a URL and get back structured data extracted via Schema.org, __NEXT_DATA__ or AI-generated rules:

result = su.get_parsed("https://www.walmart.com/ip/12345")
print(result.page_type)    # e.g. "product"
print(result.source)       # how it was extracted
print(result.data)         # the fields

# If a parse ever comes back wrong, force a fresh set of rules:
result = su.get_parsed(url, refresh_rules=True, rules_hint="price is missing")

Google search (SERP)

serp = su.serp("web scraping api", pages_to_check=2, proxy_country="US")

Google Local (Maps)

# Local business listings for a search and market
local = su.google_local("coffee shops in chicago", proxy_country="US", gl="us")
for biz in local["results"]:
    print(biz["name"], biz["rating"], biz["reviews"], biz["address"])

Oopbuy product search

# Search Oopbuy sourcing channels (1688, Taobao, official)
goods = su.oopbuy_search("wireless earbuds", channel="1688", sort="best_selling")
for item in goods["results"]:
    print(item["title"], item["price"], item["monthSold"], item["url"])

Cookies and the serving proxy

page = su.get_page_with_cookies("https://example.com")
print(page.html, page.cookies, page.proxy)

Images

data = su.get_image("https://example.com/photo.jpg")
open("photo.jpg", "wb").write(data)

Skyscanner plugins

# Resolve a place name to entity IDs, then search
locs = su.skyscanner.flight_locations("London")
flights = su.skyscanner.flights(
    origin="London", dest="New York",
    depart_date="2026-09-01", adults=1, currency="USD",
)

hotels = su.skyscanner.hotels(destination="Madrid", checkin="2026-09-01", checkout="2026-09-03")
cars = su.skyscanner.carhire(pickup="Madrid", pickup_datetime="2026-09-01T10:00", dropoff_datetime="2026-09-03T10:00")

Async

Every method has an async twin on AsyncClient:

import asyncio
from scrapeunblocker import AsyncClient

async def main():
    async with AsyncClient(api_key="YOUR_API_KEY") as su:
        html = await su.get_page_source("https://example.com")

asyncio.run(main())

Error handling

Non-2xx responses raise typed exceptions, all subclasses of ScrapeUnblockerError:

from scrapeunblocker import (
    Client,
    BlockedError,
    PaymentRequiredError,
    RateLimitError,
    UpstreamOutageError,
)

su = Client()
try:
    html = su.get_page_source("https://example.com")
except BlockedError:
    ...   # 403: the target blocked every bypass path (not billed)
except PaymentRequiredError:
    ...   # 402: quota, credit limit, or a failed payment - fix billing
except RateLimitError:
    ...   # 429: slow down
except UpstreamOutageError:
    ...   # 503: the target site itself is down - retry later

Every one of these subclasses ScrapeUnblockerError, so a single except ScrapeUnblockerError still catches everything, and the 402 and 401 subclasses can be caught by their base class when you do not need to tell them apart.

Transient failures (429, 502, 503, 504 and network errors) are retried automatically with exponential backoff; tune with Client(max_retries=...). A 401 or 402 is never retried - it clears when the key or the billing state changes, not on another attempt. Neither is billed or counted against your quota, because the request is refused before anything is scraped.

Billing errors (402)

The three billing blocks share a status code and differ only in their message, so the client raises a dedicated exception for each:

from scrapeunblocker import (
    Client,
    CreditLimitExceededError,
    PaymentFailedError,
    QuotaExceededError,
)

su = Client()
try:
    html = su.get_page_source("https://example.com")
except QuotaExceededError:
    ...   # plan quota (plus any overage allowance) is used up for this period
except CreditLimitExceededError:
    ...   # unpaid balance passed the account credit limit
except PaymentFailedError:
    ...   # card declined three times - update the payment method

When more than one applies, the most serious wins: failed payment outranks credit limit, which outranks quota. All three lift by themselves once the billing state changes - access returns within about a minute, and the API key stays the same. One catch worth knowing: subscribing to a new plan does not clear PaymentFailedError, because the old unpaid invoice stays open until it is paid.
