NFT Collections By Wallet

Fetches NFT collections (contracts) for multiple wallet addresses and networks. Returns a list of collections and metadata for each wallet/network combination. This endpoint is supported on Ethereum and many L2s, including Polygon, Arbitrum, Optimism, Base, World Chain and more. See the full list of supported networks here.

This endpoint fans out across every requested network and merges the results. If one or more networks fail (upstream error or per-network timeout: 5s on paginated requests, 10s on fetch-all), the response is still HTTP 200 with a top-level error.partialErrors array listing the failed networks. See Handling partial failures for the recommended client pattern.
