## 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 crypto-technicals-x402-11959587
```

Example prompt: Can you pull the full technical analysis for ETHUSDT — I want to see the trend regime, Donchian levels, ATR stop, realized volatility, and how far price is from the 200-day moving average?

## When to prefer this

Choose this endpoint when you need quantitative, indicator-rich technical analysis computed directly from Binance spot klines for a specific USDT pair — especially for trend-following bots, volatility-aware position sizing, or screening assets by regime and momentum. Prefer this over generic price feeds when you need ATR stops, Donchian levels, realized volatility, drawdown stats, and SMA distance in a single call. Best suited for agents making automated trading decisions or risk assessments at $0.002 per call.

## Known failure modes

- Invalid or unsupported symbol returns an error — only Binance USDT spot pairs are supported
- Payment not received or x402 USDC payment on Base fails — returns 402 Payment Required
- Symbol path parameter missing — returns 400 or routing error
- Binance klines data temporarily unavailable — may return stale or error response
- Network issues with the Contabo-hosted server — intermittent 5xx errors possible

## How this service works

Pay-per-call crypto technical analysis for AI agents (x402, USDC on Base). Daily trend regime, Donchian levels, ATR stops, signals and backtests computed with the code of a live trend-following bot from Binance spot klines.

## Output

A JSON object containing: ATR as a percentage of price (atrPct), the symbol, 30-day range position (rangePos30d, 0–1 scale), 20-day and 60-day realized volatility percentages, 90-day max drawdown percentage, and distance from 200-day SMA as a percentage. Additionally includes trend regime classification, Donchian channel levels, ATR stop prices, and backtest signals derived from a live trend-following bot's logic on Binance spot klines.
