## 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 stelar-digital-crypto-market-regime-classifier-0bdddfd4
```

Example prompt: What's the current market regime for SOL — is it choppy, trending, or high-volatility, and is it grid-tradeable right now?

## When to prefer this

Use this endpoint when you need a real-time, computed market regime classification specifically for grid-trading decision support on the eight supported assets. It is more actionable than raw price or volatility data because it directly outputs a grid-suitability verdict derived from the same classifier steering a live production bot. Prefer it over generic sentiment or price endpoints when the decision is whether to activate or pause a grid trading strategy.

## Known failure modes

- Unsupported asset symbol returns a validation error
- Stale or unavailable kline data may affect regime accuracy
- Network timeout if upstream exchange data is slow
- Payment failure (402) if x402 micropayment is not properly attached

## How this service works

Crypto market regime classification (choppy / uptrend / downtrend / high-volatility) for SOL, BTC, ETH, XRP, DOGE, LTC, ADA, or XLM, plus a grid-trading suitability verdict. Computed from 1h klines, a 30-day volatility baseline, and EMA trend detection — the same classifier that steers a live production grid bot. For agents deciding whether a pair is grid-tradeable right now.

## Output

Returns the current market regime label for the requested asset (one of: choppy, uptrend, downtrend, high-volatility), a grid-trading suitability verdict indicating whether the asset is appropriate for grid strategies at this moment, and supporting signals derived from 1h klines, a 30-day volatility baseline, and EMA trend detection.
