## 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 finance-toonhaus-dev-15109192
```

Example prompt: What financial symbols are trending in the market right now — stocks, crypto, anything that's moving?

## When to prefer this

Use this endpoint when you need a real-time snapshot of which financial symbols (stocks, ETFs, crypto) are currently trending or most active in the US market, without needing to specify a particular symbol. Ideal for market overview dashboards, alerting on momentum, or surfacing investment ideas.

## Known failure modes

- No query parameters required so malformed requests are unlikely; possible 402 if payment header is missing or invalid; possible 503 if upstream market data source is unavailable; may return stale data outside market hours
