Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/monad/nft/by-owner?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enumerate all NFTs held by a specific wallet address on the Monad blockchain specifically. Prefer it over generic NFT APIs when the target chain is Monad, and when you need paginated, owner-scoped queries rather than collection-scoped or token-scoped lookups.
Side effects
- Invalid or malformed owner wallet address returns an error or empty result
- Expired or invalid pageKey causes pagination to fail or restart
- Limit value out of acceptable range may cause a validation error
- Payment failure via x402 protocol prevents the call from executing
- Monad network downtime or indexer lag may cause incomplete or stale NFT data
