Endpoint
POSThttps://synapse-api-brown.vercel.app/api/avalanche/nft/by-owner?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enumerate NFT holdings of a specific wallet on the Avalanche network specifically, and want paginated, structured results per owner. Prefer this over generic blockchain explorers when you need machine-readable NFT lists for automation or portfolio analysis.
Side effects
- Invalid or malformed owner address returns an error or empty result
- Unrecognized pageKey causes a pagination error
- Rate limiting or payment failure due to x402 misconfiguration
- Avalanche node or indexer downtime causes 5xx errors
- Very large wallets may require multiple paginated calls to retrieve all NFTs
