## 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-hub-coinbase-realtime-data-58a813ab -d '<json body>'
```

Example prompt: Can you pull the latest real-time Coinbase data for BTC-USD right now — I need live price and trading info?

## When to prefer this

Choose this endpoint when you need real-time Coinbase market or trading data and are operating in an x402 micropayment-enabled environment on Base. It is ideal for agents that already have USDC on Base and want pay-per-query access without managing Coinbase API keys directly. Prefer this over direct Coinbase API calls when you want a keyless, wallet-native access pattern.

## Known failure modes

- Payment not accepted – x402 micropayment of ~$0.14 USDC not fulfilled, returns 402
- Invalid or malformed query parameter – upstream Coinbase API rejects the query
- Upstream Coinbase API unavailable – proxy returns error from the upstream
- Rate limiting or quota exceeded on the underlying Coinbase API
- Network timeout if real-time data feed is slow or congested
