## 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 synapse-api-linea-token-metadata-lookup-343a92ca -d '<json body>'
```

Example prompt: Can you look up the token metadata — name, symbol, and decimals — for the contract address 0x1234...abcd on the Linea blockchain?

## When to prefer this

Use this endpoint when you need fast, on-demand token metadata specifically for the Linea blockchain network. Prefer it over generic multi-chain explorers when you know the target chain is Linea and want a simple pay-per-call lookup without API key management.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address does not exist on Linea — returns null or not found
- Contract is not a standard ERC20/token contract — metadata fields may be absent
- Payment failure via x402 protocol prevents the call from completing
- Network timeout or RPC node unavailability on Linea

## Output

Returns token metadata for the specified Linea contract address, typically including the token name, symbol, number of decimals, and possibly total supply or other ERC20-standard fields.
