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
A list of NFTs owned by the specified wallet address on Unichain, including token identifiers and associated metadata, plus a pagination key to retrieve subsequent pages if more results exist.
Example use cases
NFT portfolio audit for a wallet
“Can you pull all the NFTs held by wallet 0xDead...Beef on Unichain? I want to see what tokens they own — show up to 50 at a time.”
NFT gallery display for a dApp
“Fetch the first 10 NFTs owned by 0x1234...5678 on Unichain so I can display them in the user's gallery — use pagination if there are more.”
Ownership verification for token gating
“Check whether wallet 0xAbCd...EfGh owns any NFTs on Unichain — I need to verify they hold at least one to grant them access.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/unichain/nft/by-owner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-per-call NFT ownership lookups specifically on the Unichain network without committing to a subscription. Ideal for agents that occasionally need to audit wallet NFT holdings, power token-gating checks, or build NFT galleries with paginated on-chain data. Prefer this over generic RPC calls when you want a structured, indexed NFT ownership response rather than raw blockchain data.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Unichain network outages may cause timeouts or 5xx errors
- Payment failure via x402 if USDC balance is insufficient
- Pagination key mismatch or expiry may return incorrect pages
- Empty array returned for wallets with no NFTs on Unichain (not an error)
