Example use cases
NFT collection sales history
“Get me the most recent 100 NFT sales for the contract 0xd5ac45B9A7e2a8e5E0a1234 on Gnosis, sorted descending by block, covering blocks 29000000 to 30000000.”
On-chain market activity audit

Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/gnosis/nft/salesWhen to prefer
Use this endpoint when you need on-chain NFT sale data specifically from the Gnosis (xDai) network and want to filter by contract address or block range. Prefer this over general blockchain explorers when you need programmatic, pay-per-call access to paginated sale events without managing your own Gnosis RPC node.
Side effects
- Invalid contract address format returns validation error
- Block range too large may cause timeout or truncated results
- fromBlock greater than toBlock returns empty or error response
- Network or RPC node unavailability causes 5xx errors
- Payment failure (x402) blocks the request before processing
