Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 api-carbon-cashmere-de-2b43e24a
```

Example prompt: Pull the ML anomaly log for BTC from carbon-cashmere and show me everything with severity 'high' or 'critical', including the RSI, volume ratio, and funding z-score features so I can understand what patterns triggered each alert.

## When to prefer this

Use this endpoint when you need historical ML-detected anomaly records with rich feature metadata for crypto markets — especially when you need to trace ML feature provenance, mine anomaly patterns, build alerting logic, or analyze what quantitative signals (RSI, volume ratio, funding z-score) drove a given anomaly classification. Prefer over generic price APIs when anomaly-centric, feature-rich data is the goal.

## Known failure modes

- Invalid symbol returns empty results or 404
- Unknown severity filter value returns 400 bad request
- No anomalies match the filter criteria — returns empty array
- Rate limiting or payment failure returns 402 or 429
- Service unavailable during data pipeline refresh — 503
