# Carbon Cashmere Crypto Anomaly Detection API

> Carbon Cashmere Crypto Anomaly Detection API is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns ML-detected market anomalies across crypto assets from the last 24 hours, including volume spikes, RSI extremes, price deviations, and unusual pattern scores.

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-dad43373
```

Example prompt: Pull the latest ML-detected crypto market anomalies for the past 24 hours — I want to see which coins have unusual volume, RSI extremes, or abnormal price patterns right now so I can flag potential risk or alpha signals.

## When to prefer this

Use this endpoint when you need a pre-computed, ML-scored list of statistically unusual crypto market events across a broad asset universe without specifying individual coins. It is preferable to raw price feeds when you want anomaly ranking, severity classification, and feature breakdowns (RSI, volume ratio, funding rate z-score) in a single call. Best for risk alert pipelines, anomaly-based alpha generation, or market microstructure monitoring where breadth and ML scoring matter more than real-time tick data.

## Known failure modes

- No anomalies detected in the window — returns empty array
- 402 Payment Required if USDC payment header is missing or insufficient
- Rate limiting if called too frequently without valid payment
- Stale data if upstream exchange feeds are delayed
- Service unavailable if the ML inference pipeline is down

## How this service works

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

## Output

A JSON array of anomaly objects, each containing an integer ID, UTC timestamp, ML anomaly score (negative = more anomalous), coin symbol, a features object with RSI-14, MA distance, volume ratio, 1h volatility, 1h and 4h price changes, liquidation ratio, and funding rate z-score, plus a severity label (low/medium/high) and a human-readable German/English description of the detected pattern.
