## 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 httpay-xyz-api-gateway-coingecko-crypto-data-8e5c5eb5 -d '<json body>'
```

Example prompt: What's the current price of Ethereum in USD, along with its 24-hour trading volume and market cap? Pull it from CoinGecko.

## When to prefer this

Use this endpoint when you need CoinGecko crypto market data without managing your own CoinGecko API key, and you are already operating in an x402 micropayment context. Ideal for agents that need on-demand crypto price or market cap lookups billed per call at $0.001 USDC rather than a subscription.

## Known failure modes

- 402 Payment Required if USDC payment header is missing or insufficient
- 404 if the CoinGecko path does not exist or coin ID is invalid
- 429 rate limit exceeded on the underlying CoinGecko API
- 503 if CoinGecko API is unavailable
- 400 if the path format is malformed
