Technical details
Endpoint
GEThttps://x402.professorsausages.com/nft/:chain/asset/:address/:tokenId/salesWhen to prefer
Use this endpoint when you need normalized, ready-to-use sale history for a single specific NFT token identified by chain, contract address, and token ID. Prefer this over raw blockchain queries when you want cleaned and cached data without parsing raw logs. Best suited for one-off lookups rather than bulk historical analysis.
Side effects
- Invalid or unsupported chain identifier returns an error
- Malformed contract address returns a validation error
- Token ID does not exist on the given contract returns empty or not-found response
- Rate limiting or payment failure returns 402 or 429 status
- Upstream blockchain node unavailability causes timeout or 503
