## 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-backtest-e47014bb -d '<json body>'
```

Example prompt: Run a 2-year backtest of the donchian_daily strategy on BTCUSDT and tell me the CAGR, win rate, max drawdown, and profit factor.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call backtest of a trend-following crypto strategy using real Binance kline data, especially if you want Donchian channel or ATR-stop signals without running your own infrastructure. Best when cost-efficiency per call ($0.02 USDC) and on-chain micropayment settlement via x402 on Base are acceptable.

## Known failure modes

- Invalid symbol not listed on Binance returns an error
- Strategy name not found — must match a value from GET /v1/strategies
- Years parameter outside 0.5–4 range rejected
- Payment failure via x402/USDC on Base blocks the request
- Insufficient historical data for very new tokens
- Network timeout on Contabo VPS under load

## 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.
