## How to call it through Zero

```sh
zero fetch --capability jackal-move-risk-signal-85e37e73
```

Example prompt: What's the move-risk signal for NVDA right now — is it in a high or low volatility tier for the next 4 hours, and what does the historical percentile look like?

## When to prefer this

Use this endpoint when you need a fast, single-call magnitude-only volatility signal for a US-listed stock with historical context (10-year percentile) and a human-readable risk tier. Prefer it over raw IV or realized vol endpoints when you want an actionable LOW/MED/HIGH classification and plain-language recommendation without building your own percentile ranking logic. Best suited for pre-trade risk checks, intraday position monitoring, or automated alerts where directional prediction is not needed.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Non-US or delisted tickers may not be supported
- Payment failure (x402) if USDC balance is insufficient
- Cloudflare tunnel downtime causing 502/503 errors
- Missing required 'sym' query parameter causes request rejection

## How this service works

Jackal Move-Risk Signal: expected |move| over next 240 min with 10-year percentile, LOW/MED/HIGH tier, and plain-language ACTION. Magnitude (validated), not direction.

## Output

Returns the expected absolute price move magnitude for the requested US stock over the next 240 minutes, a percentile ranking against 10 years of historical data, a categorical risk tier (LOW, MED, or HIGH), and a plain-language action recommendation. Does not predict direction — only magnitude of potential move.
