## 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 orders-of-magnitude-crypto-prices-api-d9c0ff7c
```

Example prompt: What are the current prices for major cryptocurrencies right now? Give me the latest data in JSON format.

## When to prefer this

Choose this endpoint when you need quick, cheap, micropayment-gated crypto price lookups at $0.01 USDC per call and are already integrated with the x402 payment protocol. It is well-suited for lightweight agents or bots that need real-time price checks without a subscription-based API key. Prefer alternatives with documented response schemas if you need guaranteed field names or historical data.

## Known failure modes

- 402 Payment Required if x402 payment header is missing or insufficient
- Invalid format parameter returns unexpected or empty response
- Stale or unavailable price data if upstream market feed is down
- Network timeout from Railway-hosted deployment under load
- Empty response schema means exact fields returned are undocumented and may vary
