Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/ronin/nft/sales?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need NFT sales data from the Ronin blockchain (used by Axie Infinity, Sky Mavis games). Prefer it over generic NFT APIs when Ronin-native data is required and you need block-level filtering with ascending/descending sort control.
Side effects
- Invalid contract address format returns an error
- fromBlock greater than toBlock returns empty or error
- Exceeding limit bounds may return truncated results or an error
- Block range too wide may time out or return partial data
- Payment failure (x402) blocks the request before execution
