## How to call it through Zero

```sh
zero fetch --capability api-carbon-cashmere-de-fe6b0aae
```

Example prompt: Show me the high-severity market anomalies for BTC right now — specifically funding rate extremes and liquidation density signals.

## When to prefer this

Choose this endpoint when you need real-time, multi-category anomaly detection across crypto markets with structured severity and type filtering — especially for quantitative research pipelines, AI agent-based market surveillance, or when you need to identify confluence of multiple anomaly types simultaneously. Prefer over generic OHLCV or indicator endpoints when the specific goal is anomaly/outlier detection rather than trend following.

## Known failure modes

- Invalid or unsupported symbol returns empty results or 404
- Unknown anomaly type filter returns error or empty array
- Severity filter value outside allowed enum returns validation error
- Payment not processed (x402 payment required) returns 402 status
- Rate limit exceeded returns 429 status
- No anomalies currently detected returns empty array with 200 status

## How this service works

Professional crypto market intelligence. Real-time prices, signals, and market scoring.

## Output

A list of real-time anomaly signal objects across up to 16 quantitative categories, each with a type label (e.g. funding_rate_extreme, liquidation_density, volume_irregularity, price_spike, open_interest_divergence, correlation_breakdown, confluence), severity rating, symbol, and metric values. Results are filterable by anomaly type, severity, and coin symbol.
