# QuantOracle Regime Classifier

> QuantOracle Regime Classifier is a paid API for AI agents from api.quantoracle.dev, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-14).

Classifies market regime (trend, volatility, risk) from a price series and returns RSI, SMA, trend direction, and a suggested strategy.

## 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-quantoracle-dev-ed5c67bd -d '<json body>'
```

Example prompt: Classify the market regime for this 50-bar close series: [100.5, 101.2, 100.8, ..., 124.4] — use RSI period 14, SMA period 20, and volatility window 10, and tell me whether it's risk-on or risk-off and what strategy is suggested.

## When to prefer this

Use this endpoint when you need a fast, multi-dimensional market regime snapshot from raw close prices, combining momentum (RSI), trend (SMA slope), and volatility into a single composite label and actionable strategy suggestion. Prefer it over raw indicator libraries when you want a pre-integrated, opinionated regime classification with a suggested strategy rather than computing individual indicators separately.

## Known failure modes

- Insufficient price data — fewer closes than the required window periods returns an error
- Invalid period parameters — non-integer or zero/negative values for rsi_period, sma_period, or vol_window
- Malformed closes array — non-numeric values or empty array
- Payment failure — x402 payment not processed, returns 402
- Rate limit exceeded — too many requests in a short window

## How this service works

QuantOracle: /v1/indicators/regime-classify

## Output

Returns RSI value, SMA, trend label (e.g. UPTREND), composite regime (e.g. RISK_ON), direction (UP/DOWN), volatility ratio, volatility regime (NORMAL/HIGH/LOW), realized close-to-close volatility, 5-day and 20-day slope percentages, price vs SMA percentage, and a suggested strategy string (e.g. TAKE_PROFITS).
