Endpoint
POSThttps://synapse-api-brown.vercel.app/api/ink/nft/salesWhen to prefer
Use this endpoint when you specifically need NFT sales data from the Ink blockchain network and can filter by block range or contract address. Prefer this over generic blockchain explorers when you need structured, paginated sales event data via a simple pay-per-call API without managing your own node infrastructure.
Side effects
- Invalid or non-existent contract address returns empty results or an error
- fromBlock greater than toBlock causes a validation error or empty result set
- Exceeding allowed limit values may result in truncated or error responses
- Network or upstream blockchain node unavailability causes timeout or 5xx errors
- Missing required contractAddress field returns a 400 bad request
