## 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 meterly-ai-coinranking-proxy-pay-per-call-cryptocurrency-rankings-857950ad -d '<json body>'
```

Example prompt: Search Coinranking for the top 20 cryptocurrencies by market cap and give me their current prices and rankings.

## When to prefer this

Use this endpoint when you need pay-per-call access to Coinranking cryptocurrency rankings and market data without managing a Coinranking API key, and when you are operating in a USDC/x402 payment environment on Base Mainnet. Prefer this over direct Coinranking access when your agent infrastructure is already set up for x402 micropayments.

## Known failure modes

- Payment not received — 402 error if USDC payment via x402 protocol is not completed
- Invalid or missing query field — 400 error if required 'query' field is absent
- Coinranking upstream unavailable — 502/503 if underlying Coinranking API is down
- Malformed request body — 422 if JSON schema is invalid
- Limit parameter out of range — unexpected truncation or error if limit is too large
