Technical details
Endpoint
POSThttps://public.zapper.xyz/x402/nft-balancesWhen to prefer
Use this endpoint when you need on-chain NFT holdings data for one or more wallet addresses and want Zapper's aggregated, multi-chain indexed view. Prefer this over raw RPC calls when you need normalized, multi-collection NFT data without running your own indexer.
Side effects
- Invalid wallet address format returns an error
- Unsupported network or chain returns empty or error response
- Rate limiting or quota exceeded returns 429 or payment required
- Address with no NFTs returns empty balances array
- Payment not accepted or x402 protocol failure blocks request
