## 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 signalbrew-live-ticker-1399e1d3
```

Example prompt: What's the current live price of BTC/USDT on Binance — including the bid, ask, 24h change, and volume?

## When to prefer this

Choose this endpoint when you need a lightweight, real-time price snapshot (bid/ask/last/volume/change) for a specific crypto pair on a named exchange, without requiring an API key or subscription — ideal for agents that call on-demand and pay per use in USDC. Prefer this over subscription-based market data APIs when query volume is low or unpredictable and you want zero setup friction.

## Known failure modes

- Invalid exchange name returns an error or empty response
- Unsupported trading symbol/pair returns an error
- Payment failure via x402 protocol blocks the response
- Network timeout if exchange data feed is temporarily unavailable
- Malformed request path (wrong exchange or symbol format) returns 4xx error
