## 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 rotary-agency-coinbase-free-data-api-151bee60
```

Example prompt: Can you fetch the current Coinbase market data for Bitcoin — I need the latest spot price and any available exchange info?

## When to prefer this

Choose this endpoint when you need low-cost access to Coinbase public data without setting up a direct Coinbase API integration, and when paying $0.002 per call via x402 micropayment is acceptable. It is best for lightweight or infrequent queries where the overhead of a full Coinbase API key setup is not warranted.

## Known failure modes

- Payment of $0.002 USDC not received — returns 402 Payment Required
- Coinbase upstream API unavailable — returns 502 or 503
- Rate limit exceeded on the upstream Coinbase API — returns 429
- Malformed request parameters — returns 400 Bad Request
- No data available for requested asset or pair — returns empty or null fields in JSON
