## How to call it through Zero

```sh
zero fetch --capability pak-labs-catalyst-events-api-85c3ca4d
```

Example prompt: Pull the latest scored catalyst events from Pak Labs — I want to see the direction, 8-factor score, and provenance for each event so I can identify the strongest signals.

## When to prefer this

Choose this endpoint when you need pre-scored, multi-factor catalyst events with directional signals and source provenance — particularly useful for event-driven trading strategies, systematic screening, or research workflows where raw news or unscored event feeds are insufficient. Prefer this over generic news APIs when you specifically need quantified catalyst signals with directional classification.

## Known failure modes

- Invalid or unsupported query parameters return a 400 error
- Payment not completed results in a 402 Payment Required response
- No matching catalyst events for the given filters returns an empty result set
- Rate limiting or quota exceeded returns a 429 error
- Service downtime returns a 503 error
