## How to call it through Zero

```sh
zero fetch --capability crypto-technicals-x402-09d8a399
```

Example prompt: Can you pull the daily trend regime, Donchian channel levels, and ATR stop for SOLUSDT and tell me if there's a current buy or sell signal?

## When to prefer this

Choose this endpoint when you need computed trend-following technical indicators (Donchian channels, ATR stops, trend regime, signals) for a Binance USDT spot pair, especially when you want backtest-validated outputs from a live bot's logic rather than raw price data. Prefer this over raw price endpoints when you need actionable trading signals, not just quotes.

## Known failure modes

- Invalid or unsupported symbol returns an error or empty result
- Binance kline data unavailable causes computation failure
- Payment not processed via x402/USDC results in 402 Payment Required response
- Network issues with Contabo server may cause timeouts
- Symbol not listed on Binance spot returns no data

## How this service works
