## 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 owlchart-radar-live-market-movers-signals-3d36c8dd
```

Example prompt: Pull up the OwlChart radar right now and tell me which crypto and stock symbols are moving the most — I want to see the top gainers and losers with their percentage changes.

## When to prefer this

Choose this endpoint when you need a real-time, broad-market radar view of the biggest movers across crypto and stocks in a single call. It is particularly useful for momentum trading workflows, breakout detection, and pre-session scanning. Prefer it over exchange-specific APIs when you want aggregated cross-market signal in one request, and over news APIs when you want price-action data rather than sentiment.

## Known failure modes

- Payment not received — 402 returned if USDC payment header is missing or insufficient
- Rate limiting — repeated rapid calls may be throttled
- Empty movers list — may occur during off-hours or low-volatility periods
- Stale data — read_at timestamp may lag if upstream exchange feeds are delayed
- Invalid parameters — malformed query fields return error response
