Example use cases
Example prompt
“Can you check the provenance and ownership of this NFT — it's token ID 4521 of the contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum — I want to know who owns it and whether it looks like a scam before I buy it.”
Technical details
Endpoint
GEThttps://x402.professorsausages.com/nft/:chain/asset/:address/:tokenId/provenanceWhen to prefer
Use this endpoint when you need quick, low-cost provenance and ownership data for a specific NFT — especially for scam-checking before a purchase. Prefer this over full blockchain explorers when you want a pre-parsed, agent-friendly response at $0.005 per call. Best for spot-checks on individual tokens rather than bulk analytics.
Side effects
- Token ID or contract address not found on the specified chain — returns 404 or empty result
- Unsupported chain specified — returns error indicating invalid chain parameter
- Mint info not exposed by the chain/contract — partial result returned with available fields only
- Cached data up to 24h old may not reflect very recent transfers or sales
- Rate limiting or payment failure returns 402 Payment Required
