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 list of NFTs owned by the specified wallet address on the Optimism chain, including token metadata (contract address, token ID, name, image, description), along with a pagination key for fetching subsequent pages when the owner holds more NFTs than the requested limit.
Example use cases
NFT portfolio audit for OP wallet
“What NFTs does the wallet 0x742d35Cc6634C0532925a3b8D4C9B3B8e1a2F3D4 own on Optimism? Grab up to 100 results.”
NFT gating for Optimism holders
“Check whether wallet 0xDeadBeef00000000000000000000000000000001 holds any NFTs on Optimism — I need to verify ownership before granting access.”
Paginated NFT inventory fetch
“I need to page through all NFTs owned by 0xUser...5678 on Optimism — start from where I left off using page key 'abc123' and give me the next 25 items.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/optimism/nft/by-owner?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to enumerate NFT holdings for a wallet address on the Optimism L2 network and want pay-per-call pricing without a subscription. Prefer this over general Ethereum mainnet NFT APIs when the user is interested in Optimism-native or bridged NFTs on OP chain.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Network/RPC unavailability on Optimism causes timeout or 5xx
- Missing required 'owner' field returns a validation error
- Invalid pageKey causes a pagination failure or restarted result set
- Rate limiting or payment failure (x402) blocks the request
