Endpoint
POSThttps://synapse-api-brown.vercel.app/api/ink/nft/by-ownerWhen to prefer
Use this endpoint when you need to enumerate all NFTs held by a specific wallet address specifically on the Ink blockchain network. Prefer this over generic NFT APIs when your use case is Ink-specific and you need pay-per-call, low-cost access without subscription overhead via x402 micropayments.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Unsupported or non-existent address on Ink network returns empty NFT list
- Invalid pageKey causes pagination failure or unexpected results
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Network timeout or upstream blockchain node unavailability
