## 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-x402-24012b5c
```

Example prompt: What's the current trend regime and ATR stop level for BTCUSDT — is the trend-following model signaling long or short right now?

## When to prefer this

Choose this endpoint when you need daily-timeframe trend-following technical analysis — specifically Donchian channel levels, ATR stops, trend regime classification, and trade signals — computed from live Binance spot klines. It is particularly suited to AI agents that need a structured, pay-per-call (no subscription) technical brief to inform trading decisions or monitor market conditions. Prefer it over generic market data APIs when you want backtest-validated signals from a live trend-following system rather than raw OHLCV data.

## Known failure modes

- Unknown or unsupported symbol returns an error or empty facts object
- Binance kline data unavailable (exchange downtime) may result in stale or missing indicators
- Payment failure via x402/USDC on Base results in 402 response before any data is returned
- Malformed symbol string (e.g. missing quote currency) may cause a processing error
- Rate limits or server overload on the Contabo-hosted instance may cause timeouts

## 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: a 'brief' field with a human-readable narrative summary (e.g. 'BTCUSDT closed at 77225 …'), a 'facts' object with structured technical indicators (trend regime, Donchian high/low channel levels, ATR stop distances, trade signals, and backtest metrics), and a 'symbol' field echoing the requested trading pair.
