## How to call it through Zero

```sh
zero fetch --capability tokenaru-vercel-app-81231744
```

Example prompt: What is the contract address for USDC on Base? I need the chain ID and CoinGecko metadata too.

## When to prefer this

Use this endpoint when you need to resolve a human-readable token or coin name into its on-chain contract address and chain metadata, especially when the user has provided a natural language description like 'USDC on Base' rather than a raw address. Prefer this over manual lookups when CoinGecko-sourced metadata and multi-chain support are needed.

## Known failure modes

- Token or coin not found in CoinGecko database — returns ok: false with an error message
- Ambiguous query matching multiple tokens — may return unexpected token
- Network or CoinGecko API unavailability causing lookup failure
- Token exists but has no contract address on the queried chain

## How this service works

Resolve a token contract address with CoinGecko-backed metadata.

## Output

Returns a JSON object with ok status, token name, symbol, contract address, chain ID, chain name, CoinGecko platform ID, and a source field indicating whether the data came from cache or live CoinGecko API.
