## 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 token-metadata-lookup-5a3a1d65
```

Example prompt: Can you look up the token metadata for the contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — I need its name, symbol, and any other info available?

## When to prefer this

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.

## Known failure modes

- 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

## 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"}.
