Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/apechain/nft/by-ownerWhen to prefer
Use this endpoint when you need to enumerate all NFTs held by a specific wallet address specifically on the ApeChain (APE ecosystem) network. Prefer this over generic multi-chain NFT APIs when you need ApeChain-specific data or are building APE-ecosystem tooling. It supports pagination for large wallets and is priced cheaply at $0.01 per call via x402 micropayments.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Non-existent ApeChain address returns an empty NFT list
- Invalid pageKey causes pagination failure or restarted result set
- Limit value out of acceptable range may cause validation error
- Network or upstream ApeChain node outage returns 5xx error
- Wallet with thousands of NFTs may time out without appropriate pagination
