Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/apechain/nft/salesWhen to prefer
Use this endpoint when you need on-chain NFT sales data specifically from the ApeChain network, especially when filtering by contract address or block range is needed. Prefer this over general NFT APIs when ApeChain-specific data is required and you want pay-per-call pricing without a subscription.
Side effects
- Invalid contract address format returns an error or empty results
- fromBlock greater than toBlock causes query failure or empty response
- limit value out of acceptable range may return an error
- Non-existent contract address returns empty sales list
- Network or RPC issues may cause timeout or 5xx errors
- Payment failure via x402 prevents endpoint access
