Endpoint
POSThttps://synapse-api-brown.vercel.app/api/mantle/nft/by-ownerWhen to prefer
Use this endpoint when you specifically need to enumerate NFTs owned by a wallet address on the Mantle blockchain. Prefer this over generic NFT APIs if your use case targets Mantle specifically. It is ideal for portfolio display, NFT-gating, ownership verification, and paginated browsing of large NFT collections on Mantle.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Wallet with no NFTs on Mantle returns an empty list
- Invalid pageKey causes pagination failure or unexpected results
- Rate limiting or payment failure (x402) blocks the request
- Mantle network RPC unavailability causes timeout or error
