How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
Returns the NFT token standard (ERC-721 or ERC-1155), the current owner's Ethereum address, and the token URI as an on-chain string. Note: the token URI is returned as untrusted text and is never fetched by the service.
Example use cases
Verify NFT ownership before granting access
“Can you check who currently owns token ID 7 on the Base ERC-721 contract at 0x2953399124F0cBB46d2CbACD364f48AB8B977B3? I need to verify ownership before granting a holder benefit.”
Retrieve NFT metadata URI for display
“Get me the token URI for ERC-1155 token ID 100000000000000000000000000000001 on Ethereum contract 0x76BE3b62873462d2142405439777e971754E8E4 so I can fetch the artwork metadata.”
Audit NFT token provenance on Base
“Look up the current owner of token 0 on the Base chain NFT contract 0xd4416b13d2b3a9abae7acd5d6c2bbdbe25686401 and return the standard type and token URI for my provenance report.”
Technical details
Endpoint
POSThttps://tanod.dev/v1/chain/nft?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, read-only on-chain lookup of NFT ownership or token URI on Ethereum or Base without running your own RPC node. It is well-suited for ownership verification, metadata URI resolution, and NFT provenance checks. Prefer this over general Web3 RPC calls when you want a simple pay-per-call HTTP API without managing wallet keys or node infrastructure.
Side effects
- Invalid contract address format returns a validation error
- Token ID does not exist on the contract (reverts on-chain) returns an error
- Contract is not an ERC-721 or ERC-1155 contract — call may fail or return unexpected data
- Unsupported chain value returns an enum validation error
- Network or RPC timeout causes a transient failure
- Token URI may be empty or return a malformed string if the contract sets it that way
