## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-data-tools-erc-20-token-info-lookup-0033d717
```

Example prompt: What's the name, symbol, decimals, and total supply for the ERC-20 token at contract address 0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85 on Optimism?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
