Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/optimism/nft/sales?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need indexed NFT sales data specifically on the Optimism L2 network and want to filter by block range or contract address. It is preferable over general blockchain RPC calls because it abstracts raw event log parsing, and preferable over Ethereum mainnet endpoints when your NFT collection is deployed on Optimism. Useful for analytics, auditing, and monitoring workflows where pay-per-call pricing is more economical than a subscription.
Side effects
- Invalid or non-existent contract address returns empty results or an error
- fromBlock greater than toBlock causes a bad request error
- Limit value of 0 or negative integer may result in validation error
- Block range too large may cause timeout or truncated results
- Payment failure via x402 protocol returns 402 Payment Required before data is served
