## 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 sna4an-coinranking-crypto-data-api-34576db9 -d '<json body>'
```

Example prompt: Can you fetch the top 10 cryptocurrencies by market cap right now using the CoinRanking coins endpoint, filtered to USD?

## When to prefer this

Use this endpoint when you need ranked cryptocurrency market data — prices, market caps, volumes — especially via the CoinRanking dataset. Prefer this over generic crypto APIs when your agent workflow already uses x402 micropayment infrastructure and needs a cost-effective per-call pricing model for market data lookups.

## Known failure modes

- Invalid RapidAPI sub-endpoint path returns 404 or empty response
- Missing or malformed query parameters may return incomplete data
- Payment of 0.12 USDC required per call; insufficient funds results in 402 error
- Rate limiting from underlying RapidAPI gateway may throttle responses
- Unsupported coin identifiers may return null or error fields
