Endpoint
POSThttps://synapse-api-brown.vercel.app/api/linea/nft/salesWhen to prefer
Use this endpoint when you need on-chain NFT sales data specifically from the Linea blockchain, with pay-per-call pricing via x402 (no subscription required). Prefer this over general NFT data aggregators when you need raw, filtered, block-level sales events for a specific contract or time window on Linea.
Side effects
- Invalid contract address format returns a validation error
- fromBlock greater than toBlock returns an empty result or error
- Requesting too large a block range may time out or return partial data
- Unavailable or non-existent contract address returns empty results
- Network or RPC errors on Linea may cause intermittent failures
