# Carbon Cashmere Factor Analytics

> Carbon Cashmere Factor Analytics is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Computes a 4-factor decomposition (Momentum, Carry, Crowding, Volatility) for a given cryptocurrency and returns a composite 0–1 score with a directional bias label.

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-ca383248
```

Example prompt: Run the factor analytics on SOL — I want to see the momentum, carry, crowding regime, and volatility percentile breakdown, plus the composite bias label.

## When to prefer this

Use this endpoint when you need a structured, multi-factor quantitative view of a crypto asset's current market regime — especially when you want momentum, carry, crowding, and volatility synthesized into a single directional label. Prefer this over raw price endpoints when the goal is factor-based market characterization or regime detection rather than raw price lookup.

## Known failure modes

- Unsupported coin ticker returns 400 or 422 — only the 34 enumerated coins are valid
- Payment not fulfilled triggers 402 Payment Required
- Network or node outage returns 503
- Invalid path parameter format returns 400
- Stale data if underlying market feeds are delayed

## How this service works

Factor decomposition across 4 dimensions: Momentum (30d return normalized by 90d vol), Carry (annualized funding rate), Crowding (OI-delta vs. price-delta divergence with crowded_long/crowded_short/unwinding/neutral regime), and Volatility (realized 30d vol percentile over full lookback). Returns composite 0-1 score with label (bullish_bias_low_vol / bullish_bias / neutral / bearish_bias / bearish_bias_high_vol). Informational research data — not investment advice.

## Output

Returns a JSON object containing the coin symbol, a factors object with sub-scores for Momentum (30d return normalized by 90d vol), Carry (annualized funding rate), Crowding (OI-delta vs price-delta divergence, one of crowded_long/crowded_short/unwinding/neutral), and Volatility (realized 30d vol percentile); plus a composite_score (0–1) and composite_label (one of bullish_bias_low_vol, bullish_bias, neutral, bearish_bias, bearish_bias_high_vol). Accompanied by metadata (_meta).
