Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/linea/nft/by-ownerWhen to prefer
Use this endpoint when you specifically need NFT ownership data on the Linea blockchain. It supports pagination for wallets with large collections and is priced per-call via x402 micropayments, making it suitable for on-demand lookups rather than bulk batch processing. Prefer this over generic blockchain explorers when you need structured, programmatic NFT data for Linea specifically.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Non-existent address returns an empty NFT list
- Invalid pageKey causes pagination failure or error
- Network or upstream Linea RPC issues cause timeouts
- Missing required 'owner' field results in a validation error
- Rate limiting or payment failure (x402) blocks the call
