## 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 snowsignals-phase-updates-8c47bb98
```

Example prompt: Pull the latest market phase updates from SnowSignals so I can see if there's been a phase transition recently.

## When to prefer this

Choose this endpoint when you need real-time or near-real-time market phase update signals specifically from SnowSignals' phase-detection model, particularly for triggering alerts or decisions on market cycle transitions. Prefer it over the sibling 'phase boundary' endpoint when you need continuous phase update readings rather than discrete boundary detection events.

## Known failure modes

- Payment not included or insufficient — 402 Payment Required response
- Service unavailable or worker error — 5xx response
- No new phase update data available — empty result set
- Rate limiting or quota exceeded
