## 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 x402-multi-tool-api-crypto-markets-70f9d83f -d '<json body>'
```

Example prompt: Pull the top 10 cryptocurrency prices right now quoted in USD, including their 24-hour price change and market cap rank.

## When to prefer this

Choose this endpoint when you need a ranked list of multiple cryptocurrency prices and 24h changes in a single call, especially when operating in a pay-per-request agent context with no API key setup. Prefer over full exchange APIs when you want lightweight market overview data without authentication overhead.

## Known failure modes

- Invalid or unsupported quote currency (vs) returns empty or error response
- Payment not included or insufficient USDC causes 402 Payment Required response
- Limit value too high may return partial results or timeout
- Upstream price feed unavailable causes stale or missing data
