How this service works
Web page to clean Markdown for AI agents. Pay per call with x402 (USDC on Base).
Output
Returns a JSON object with the token's name, symbol, decimals, contract address, chain, whether the address is a contract, and total supply string.
Example use cases
Identify unknown token contract
“I found this contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — can you tell me what token it is, its symbol, and how many decimals it uses?”
Validate token decimals before swap
“Before I execute this trade, can you confirm the decimals for the token at 0x4200000000000000000000000000000000000042 on Optimism so I don't mess up the amount?”
Check total supply of DeFi token
“Look up the total supply and full metadata for the token at 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum.”
Technical details
Endpoint
GEThttps://138-197-15-135.sslip.io/v1/base/token-info?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, standardized ERC-20 token metadata (name, symbol, decimals, total supply) for a contract address on Base, Ethereum, Arbitrum, or Optimism, especially in agent pipelines where payment via x402/USDC is acceptable and you want a simple REST lookup without setting up your own RPC node.
Side effects
- Invalid or non-contract address returns isContract:false or error
- Unsupported chain name returns an error
- Token contract exists but does not implement standard ERC-20 metadata methods — partial data returned
- Network timeout or RPC failure results in 5xx error
- Missing required 'address' query parameter returns 4xx validation error
