How this service works
Pay-per-call e-commerce, product, price and social media data tools for AI agents, from public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.
Output
A JSON object containing the search keyword, current page, total matching lot count, and an array of lot records — each with lot ID, title, lot number, category path, artist, auction house name, location, country, currency, current bid, bid count, estimate low/high, hammer price (for past lots), sale date, sale type (live or timed), image URL, and lot URL. Also includes the data source URL and the timestamp when the data was checked.
Example use cases
Researching market value of a collectible
“Look up past auction results on Invaluable for 'Tiffany lamp' so I can see what they've been selling for — show me hammer prices and the auction houses involved.”
Monitoring upcoming Rolex auction opportunities
“Find the next upcoming Invaluable auction lots for Rolex watches — I want to see current bids, estimate ranges, and whether each sale is live or timed.”
Scouting artwork by a specific artist
“Search Invaluable for upcoming lots featuring 'Basquiat' and give me the lot titles, auction houses, locations, and estimate ranges for the first 20 results.”
Technical details
Endpoint
GEThttps://api.shopsocial-api.workers.dev/api/ecommerce/invaluable-auctions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to search auction lots globally across thousands of auction houses via Invaluable's aggregated marketplace. Ideal for price research (hammer prices on past lots), monitoring upcoming auctions for a specific keyword, or building tools around auction market intelligence. Prefer this over general e-commerce search endpoints when the context is auction-based buying, selling, or valuation — particularly for art, antiques, jewelry, watches, and collectibles.
Side effects
- Missing required 'q' parameter returns an error
- No lots found for obscure keywords returns empty lots array with total 0
- Invalid 'status' value (not 'upcoming' or 'past') may default or error
- Page number beyond available results returns empty lots array
- Rate limiting or upstream Invaluable availability issues may cause failures
- Invalid limit value outside 1-50 range may be clamped or rejected
