Example use cases

“Can you list all the NFT instances for the Bored Ape Yacht Club contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum and show me their thumbnails and metadata?”
Check NFTs held by a wallet in a contract
“Which NFTs from the contract 0x495f947276749Ce646f68AC8c248420045cb7b5e on Ethereum does the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 own?”

Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/tokens/%7Baddress_hash_param%7D/instancesWhen to prefer
Use this endpoint when you need to enumerate all NFT instances (ERC-721 or ERC-1155) minted under a specific contract on a supported blockchain, especially when you need rich metadata including images, animations, and ownership. Prefer this over generic blockchain explorers when you need Blockscout's cross-chain support and structured NFT-specific response format with thumbnails. Best for agents building NFT galleries, portfolio trackers, or collection analytics.
Side effects
- Invalid or non-existent chain_id returns 404 or empty response
- Invalid address_hash_param format returns 422 validation error
- Contract address is not an NFT contract — returns empty items array
- Pagination cursor mismatch leads to duplicate or missing items
- Rate limiting or payment failure returns 402 Payment Required
- Non-NFT (fungible) token address returns empty or malformed response
