How this service works
Which token is behind this contract? Returns the name, symbol, decimals and total supply of an ERC-20 token on Base ($0.003 per call).
Output
A JSON object containing the token's human-readable name (nom), contract address (token), and ticker symbol (symbole), e.g. {"nom": "Token", "token": "0x...", "symbole": "TKN"}.
Example use cases
Identify unknown token in wallet
“I see a token with address 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 in my wallet — can you fetch its name and symbol so I know what it is?”
Verify token symbol before trade
“Before I swap, can you confirm what the name and symbol are for the token at address 0x6B175474E89094C44Da98b954EedeAC495271d0F?”
Enrich token list with metadata
“I have a list of contract addresses and I need the name and ticker symbol for each one — start with 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2.”
Technical details
Endpoint
GEThttps://api.api-agent-ia.ch/info-token?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, lightweight token metadata (name and symbol) for a given contract address on-chain, especially when operating in a Web3 or DeFi agent workflow. It pairs well with the sibling endpoints on this provider for balance checks, security scoring, and smart contract analysis — making it useful as a first step to identify an unknown token before performing further analysis.
Side effects
- Invalid or malformed token address returns an error or empty result
- Token address not found in the provider's database returns no metadata
- Missing required 'token' query parameter causes a validation error
- Network or upstream blockchain data source unavailability causes a 500-level error
