Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/base/nft/sales?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical NFT sales data specifically on the Base network with block-level precision. It is ideal for auditing sales activity, analyzing volume trends, or monitoring a specific NFT smart contract over a defined block range. Prefer this over generic blockchain explorers when you need pay-per-call programmatic access without managing an RPC node.
Side effects
- Invalid or malformed contractAddress returns an error or empty result
- fromBlock greater than toBlock returns empty or error
- Exceeding rate limits or payment failure returns 402 Payment Required
- Non-existent contract address returns empty sales array
- Very large block ranges may time out or return partial results
