## 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 outlier-money-crypto-unusual-activity-signal-09dbd0d2 -d '<json body>'
```

Example prompt: Show me which of the top 250 crypto coins by market cap are currently displaying unusual volume or price activity compared to their own historical baseline — I want the ranked list of outliers right now.

## When to prefer this

Choose this endpoint when you need a real-time, pre-ranked snapshot of which top-250 cryptocurrencies are behaving abnormally relative to their own historical baselines — rather than absolute price/volume data. Ideal for agents that need to quickly surface early-stage anomalies without manually computing baselines across hundreds of coins. No input parameters are required, making it fast and frictionless for polling or event-driven monitoring loops.

## Known failure modes

- Upstream data feed outage returns empty or stale unusual-activity list
- Payment of $0.01 USDC not processed — returns 402 Payment Required
- POST body must be valid JSON even if empty body; malformed request returns 400
- During low-volatility market periods, the unusual list may return few or zero flagged coins
- Rate limiting or server overload may return 429 or 503

## How this service works

Real-time crypto unusual-activity signal: coins with abnormal volume/price vs their own baseline, ranked, early-flagged, across the top 250 by market cap.

## Output

A ranked array of cryptocurrency entries flagged for unusual activity, each containing coin identifiers and anomaly metrics (volume/price vs baseline), plus a summary of how many coins were scanned and an overall signal label.
