Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/monad/nft/by-owner?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain NFT ownership data specifically for the Monad network. Prefer it over generic NFT APIs when you need pay-per-call pricing via x402 and fast response times for Monad-native assets without subscribing to a larger Web3 data plan.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Missing required 'owner' field causes a 400 bad request
- Invalid pageKey leads to a pagination error or empty page
- Rate limiting or payment failure (x402) blocks the request
- Monad network data unavailability causes timeout or empty response
