Quick Start

from artmarketapi import ArtMarketAPI

client = ArtMarketAPI("amapi_live_xxxxx_xxxxx")

# Search for an artist
results = client.search.artists("Picasso")
artist_id = results["data"][0]["id"]

# Get their auction records
records = client.auction_records.list(
    artist=artist_id,
    category="painting",
    start_date="2024-01-01",
    limit=25,
)

for record in records["data"]:
    print(f"{record['title']} — ${record.get('usd_hammer_price', 'N/A'):,}")

    lot_performance="above",    # upcoming | above | within | below | not_sold | pulled
    sort_by="usd_hammer_price", # sale_date | usd_hammer_price | created_at
    sort_order="desc",
    include_analytics=True,     # requires artist filter
    limit=25,
    page=1,
)

# Get single record
record = client.auction_records.get("507f1f77bcf86cd799439012")

Comparable Sales

AI-optimized endpoint for finding similar artworks. Returns cleaner, more structured data ideal for AI integration.

# Find comparables
comps = client.comparable_sales.list(
    category="painting",
    medium="oil",
    min_width=90,
    max_width=110,
    min_height=70,
    max_height=90,
    years_back=2,
)

# Get aggregate statistics only
summary = client.comparable_sales.summary(
    artist="507f1f77bcf86cd799439011",
    category="painting",
)

Artists

# Get artist details
artist = client.artists.get("507f1f77bcf86cd799439011")

# Past auction records
history = client.artists.past_auction_records(
    "507f1f77bcf86cd799439011",
    page=1,
    sort_by="hammer_price",
)

# Sell-through rates
rates = client.artists.sell_through_rates("507f1f77bcf86cd799439011")

# SLPAE analytics
slpae = client.artists.slpae("507f1f77bcf86cd799439011")

Search

results = client.search.artists("Picasso", limit=10, page=0)

# results["data"] = [{"id": "...", "name": "Pablo Picasso"}, ...]

Market Trends

# Full market overview
overview = client.market_trends.overview(category="painting")

# Market heat index (0-100)
heat = client.market_trends.heat(category="painting", months=6)

# Emerging artists
emerging = client.market_trends.emerging()

# Category performance rankings
categories = client.market_trends.categories()

# Market regime for an artist (bull/bear/sideways)
regime = client.market_trends.regime("507f1f77bcf86cd799439011")

# Market sentiment
sentiment = client.market_trends.sentiment()

Advanced search with AI-powered semantic search.

results = client.price_database.search(
    artist="507f1f77bcf86cd799439011",
    description="blue abstract oil painting",  # semantic search
    category="painting",
    min_hammer_price=5000,

# Basic valuation
valuation = client.valuation.estimate(
    artist="Pablo Picasso",
    width_cm=100,
    height_cm=80,
    category="painting",
    medium="Oil on canvas",
)

# Advanced analysis with market context
analysis = client.valuation.analysis(
    artist="Pablo Picasso",
    width_cm=100,
    height_cm=80,
    category="painting",
)

# Find similar artworks by description
similar = client.valuation.describe(
    artist="Pablo Picasso",
    category="painting",
    width=100,
    height=80,
    description="Blue period portrait",
)

Error Handling

The SDK raises typed exceptions you can catch and handle:

from artmarketapi import (
    ArtMarketAPI,
    ArtMarketAPIError,
    AuthenticationError,
    RateLimitError,
    PlanUpgradeRequiredError,
    NotFoundError,
)

try:
    records = client.auction_records.list(artist="...")
except RateLimitError as e:
    print(f"Rate limited. Retry after {e.retry_after}s")
    print(f"Remaining: {e.rate_limit.remaining}")
except AuthenticationError:
    print("Invalid API key")
except PlanUpgradeRequiredError:
    print("Upgrade your plan to access this endpoint")
except NotFoundError:
    print("Resource not found")
except ArtMarketAPIError as e:
    print(f"API error: {e.code} - {e}")
    print(f"Request ID: {e.request_id}")

Rate Limits

Rate limit info is available after each request:

records = client.auction_records.list(artist="...")

print(client.rate_limit)
# RateLimitInfo(limit=60, remaining=59, reset=1679529600)

Plan	Requests/Min	Requests/Day	Max Page Size
Free	10	200	10
Starter	30	2,000	25
Pro	60	10,000	50
Enterprise	120	50,000	100

Context Manager

The client supports use as a context manager for automatic cleanup:

with ArtMarketAPI("amapi_live_xxxxx_xxxxx") as client:
    records = client.auction_records.list(category="painting")

client = ArtMarketAPI(
    "amapi_live_xxxxx_xxxxx",

    # Optional: override base URL (for testing or self-hosted)
