How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns a paginated list of NFTs owned by the specified wallet on the Worldchain network, including token IDs, contract addresses, NFT metadata, and a pageKey cursor for fetching subsequent pages.
Example use cases
NFT portfolio audit for a wallet
“Can you pull all the NFTs held by wallet 0x4f8a...b3c2 on Worldchain? Give me up to 100 results so I can audit their collection.”
Gating access by NFT ownership
“Check if wallet 0xDead...Beef owns any NFTs on Worldchain — I need to verify they hold at least one to grant them access to this feature.”
Paginated NFT inventory sync
“Fetch the next page of NFTs for wallet 0x1234...5678 on Worldchain using page key 'abc-cursor-xyz', limit 25 results, so I can sync the rest of their holdings.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/worldchain/nft/by-ownerWhen to prefer
Use this endpoint when you specifically need NFT ownership data on the Worldchain network and want pay-per-call pricing without a subscription. Prefer this over general blockchain explorers when building agents that need programmatic, structured NFT portfolio data for Worldchain addresses.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Non-existent address returns empty NFT list
- Rate limits or payment failure (x402) blocks the response
- Invalid pageKey cursor causes pagination error
- Network issues with Worldchain RPC result in timeout
