## 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 coingecko-coin-price-market-cap-24h-change-90b2f70c
```

Example prompt: What's the current price, market cap, and 24-hour change for Ethereum right now? Use the CoinGecko ID 'ethereum'.

## When to prefer this

Use this endpoint when you need real-time price, market cap, and 24h change for a single coin identified by its CoinGecko ID. Prefer this over the full market table endpoint when you only need data for one specific coin. Choose this over the token-by-contract-address endpoint when you already know the CoinGecko ID rather than the on-chain contract address.

## Known failure modes

- Invalid or unknown CoinGecko ID returns an error or empty result
- Rate limiting or payment failure may result in a 402 or 429 response
- Network timeout from upstream CoinGecko API
- Coin data temporarily unavailable due to CoinGecko downtime
