Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/soneium/nft/sales?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need NFT sales data from the Soneium blockchain and want to filter by block range or contract address. Prefer this over generic NFT APIs when Soneium-specific data is required, or when you need pay-per-call pricing without a subscription.
Side effects
- Invalid or malformed contract address returns an error or empty result
- fromBlock greater than toBlock causes an invalid range error
- Requesting a block range with no sales returns an empty array
- Network or RPC issues with Soneium may cause timeouts
- Unsupported order enum value returns a validation error
- Payment failure via x402 protocol blocks the request
