## 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 orchard-data-catalyst-radar-d2d3287e
```

Example prompt: Pull the latest catalyst radar scan — I want to see which symbols are moving right now and the reason behind each move, and let me know how fresh the data is.

## When to prefer this

Choose this endpoint when you need a quick, AI-annotated snapshot of notable market movers with explanations — especially useful for agents that need to act on catalyst-driven price action rather than raw price feeds. Prefer it over generic price APIs when you want human-readable reasons alongside the symbols, and when per-call micropayment via x402/USDC on Base fits your cost model.

## Known failure modes

- Payment not attached or insufficient USDC: 402 Payment Required response
- Invalid or malformed properties filter: may return empty or unexpected results
- Data staleness: fresh=false when cache is old, age_minutes will be elevated
- Cloudflare Worker downtime: 503 or timeout
- No movers detected: scan.movers array may be empty during low-volatility periods
