## 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 swaphunt-chop-vs-trend-detector-adx-based-4492b72a
```

Example prompt: Check if BTC/USDT is currently trending or just chopping on the 4h chart — I want to know whether it's safe to run a trend-following strategy right now.

## When to prefer this

Use this endpoint when you need to programmatically determine the current market regime for a crypto asset before deploying a trend-following or mean-reversion strategy. It is specifically useful as a pre-filter to avoid applying trend strategies during choppy, low-ADX markets or range strategies during strongly trending markets. Prefer this over raw price data when you want a single, pre-computed regime signal rather than computing ADX yourself.

## Known failure modes

- Unsupported asset symbol returns an error or empty result
- Invalid timeframe value (e.g. '5m') returns a validation error
- Quote currency not supported returns an error
- Payment of 0.003 USDC not provided results in 402 Payment Required
- Downstream data source unavailable causes 503 or timeout

## How this service works

ADX-based chop-vs-trend detector for an asset/timeframe: is price trending or stuck in a range? Returns a boolean + chop score. Use to avoid trend strategies in chop (and range strategies in trends).

## Output

Returns a boolean indicating whether the market is choppy (true) or trending (false), plus a numeric chop score (likely 0–100) derived from ADX analysis, allowing the agent to decide whether to engage trend-following or range-bound strategies.
