# Carbon Cashmere Crypto Market Regime Classifier

> Carbon Cashmere Crypto Market Regime Classifier is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.02/call, status down (last checked 2026-09-14).

Classifies the current crypto market into one of five regimes (accumulation, markup, distribution, markdown, high_volatility) using a Hidden Markov Model, with confidence, stability, duration, and 24-hour transition probabilities.

## Facts

- Price: $0.02/call
- Payment: x402
- Status: down

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-d70808f5
```

Example prompt: What market regime is crypto in right now — is it accumulation, markup, distribution, markdown, or high volatility — and how confident is the Hidden Markov Model, and what are the chances it shifts to a different phase in the next 24 hours?

## When to prefer this

Use this endpoint when you need a principled, probabilistic classification of the macro crypto market cycle — especially when making regime-conditional trading decisions, selecting strategy modes, or identifying macro trend shifts. Prefer this over raw technical indicators when you need a single authoritative regime label with uncertainty quantification and forward-looking transition probabilities. Complements sibling endpoints for technical indicators, trend analytics, and composite multi-factor analytics on this same platform.

## Known failure modes

- Service unavailable or internal model error returning 5xx
- Insufficient market data causing low-confidence or null regime output
- Stale or lagged HMM state if underlying price feeds are delayed
- Rate limiting or payment failure returning 402 or 429 status

## How this service works

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

## Output

Returns the current market regime label (one of: accumulation, markup, distribution, markdown, high_volatility), a confidence score for the classification, a stability metric, the duration of the current regime, and a 24-hour transition probability matrix showing likelihoods of moving to each of the five regimes.
