Example use cases
NFT collection sales analytics

Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/polygon/nft/salesWhen to prefer
Choose this endpoint when you need on-chain NFT sales data specifically from the Polygon network and want block-level precision over the query range. It is ideal for agents that need historical trade data for a specific contract without relying on third-party NFT marketplace APIs. Prefer it over general blockchain explorers when pay-per-call cost efficiency matters and you need programmatic, structured sales records.
Side effects
- Invalid or non-checksum contract address returns an error or empty result
- fromBlock greater than toBlock yields no results or a validation error
- Block range too large may cause timeout or truncated results
- Payment failure (x402) blocks the request if USDC balance is insufficient
- Network unavailability on Phantom API infrastructure returns a 5xx error
