How this service works
Call when an agent needs ERC-20 name, symbol, decimals, and totalSupply for one Ethereum mainnet token. Send token (example Circle USDC). Read-only eth_call on eip155:1. Not a contract, or no ERC-20 methods, errors. No spend. Send JSON {"token":"0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"}. Exact $0.002 USDC on Base. Try unpaid POST /v1/sandbox/eth-erc20-meta first.
Output
Returns a JSON object containing the ERC-20 token's name (string), symbol (string), decimals (integer), and totalSupply (large integer) as reported by the contract on Ethereum mainnet (eip155:1). If the address is not a valid ERC-20 contract or lacks these standard methods, an error is returned.
Example use cases
Verify token decimals before transfer
“Before I send this token amount, can you check how many decimals the ERC-20 contract at 0xdAC17F958D2ee523a2206206994597C13D831ec7 uses on Ethereum mainnet?”
Display token info in portfolio dashboard
“I want to show the full token name and symbol for 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 in my portfolio — can you pull the ERC-20 metadata for it?”
Audit total supply of a new token
“Can you fetch the total supply and decimals for the ERC-20 contract at 0x6B175474E89094C44Da98b954EedeAC495271d0F so I can verify the token economics?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/eth-erc20-meta?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need standard ERC-20 metadata (name, symbol, decimals, totalSupply) for a single Ethereum mainnet token contract and want a simple, pay-per-call interface without managing your own RPC node or Ethereum provider credentials. Prefer this over general blockchain APIs when you only need these four fields and want minimal setup.
Side effects
- Address is not a deployed contract — returns error indicating no contract found
- Contract exists but does not implement ERC-20 methods (name/symbol/decimals/totalSupply) — returns method-not-found or call revert error
- Invalid Ethereum address format — returns validation error
- Network or RPC failure — returns upstream error
- Non-mainnet address provided — only eip155:1 is supported, other chains will error
