“Fetch all NFT sales for the Mantle contract 0xdeadbeef between block 1000000 and 1050000 so I can audit trading activity during that period.”

Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/mantle/nft/sales?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need paginated, filterable NFT sales data specifically from the Mantle blockchain. It is ideal when you need to scope queries to a specific smart contract address and/or a block range, and when you want control over result ordering and volume. Prefer this over generic blockchain explorers when you need programmatic, pay-per-call access without rate-limit subscriptions.
Side effects
- Invalid contract address format returns a validation error
- fromBlock greater than toBlock returns an empty result or error
- Limit value too large may result in timeout or truncated response
- Non-existent contract address returns empty sales array
- Network congestion or Mantle RPC issues may cause delayed or failed responses
