## 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-toolbox-coin-market-data-021218c9
```

Example prompt: Can you pull the current market data for Bitcoin — price, market cap, and volume — using the x402 coin market data tool?

## When to prefer this

Choose this endpoint when you need cryptocurrency market data without signing up for an API key or managing credentials — payment via USDC on Base serves as authentication. Ideal for AI agents that need sporadic, pay-as-you-go coin price lookups at $0.003 per call without rate-limit tiers or account management overhead.

## Known failure modes

- Payment not completed or insufficient USDC balance — returns 402 Payment Required
- Invalid or unrecognized coin schema/identifier — may return empty or error response
- Network timeout on Cloudflare Worker — returns 5xx error
- Coin not supported in the dataset — returns ok:true but empty data fields

## How this service works
