How this service works
Look up the name, symbol, decimals and total supply of an ERC-20 token contract on Optimism, live from the contract. Use to identify an unknown token address or to format raw amounts; for a holder's balance use op_token_balance. Input is a ticker (USDC, WETH…) or the token's 0x contract address; an address that is not an ERC-20 contract returns 422, uncharged.
Output
A JSON object with the token's human-readable name, ticker symbol, chain name, chain ID, contract address, number of decimals, formatted total supply (e.g. '1000000000.0'), and raw total supply integer string.
Example use cases
Resolve unknown token contract metadata
“I found this contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 in a transaction — can you tell me what token it is, what chain it's on, and how many decimals it uses?”
Verify token supply before DeFi integration
“Before I integrate this ERC-20 at 0x6B175474E89094C44Da98b954EedeAC495271d0F into my app, can you pull its full token info — name, symbol, total supply, and decimals?”
Enrich portfolio data with token metadata
“I have a list of ERC-20 contract addresses from my wallet transactions and I need the human-readable name and symbol for each one — start with 0x4200000000000000000000000000000000000042.”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/op/token-info?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need canonical metadata (name, symbol, decimals, total supply) for a known ERC-20 contract address and do not need real-time price data. It is ideal for enriching transaction data, validating token contracts, or building UI labels for on-chain assets. Prefer this over price endpoints when metadata rather than market data is the goal.
Side effects
- Invalid or non-ERC-20 contract address returns an error
- Contract address exists but is not a standard ERC-20 (e.g. ERC-721 NFT) may return incomplete data
- Unsupported chain for the given contract address
- Network timeout or RPC error from the underlying chain provider
- Missing required 'token' query parameter returns validation error
