## 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-aa81c3e9 -d '<json body>'
```

Example prompt: Run the trend-following technical analysis on BTCUSDT — I want to know today's trend regime, the Donchian channel levels, ATR stop, and any current trading signals.

## When to prefer this

Choose this endpoint when you need pay-per-call, on-demand crypto technical analysis grounded in a live trend-following bot's logic — specifically Donchian channel breakouts, ATR-based stops, and daily regime classification from Binance spot klines. Prefer it over generic price feeds when you need structured trading signals and backtested strategy context rather than raw price data, and when you want micropayment-based access via x402 USDC on Base without API key subscriptions.

## Known failure modes

- Invalid or unsupported trading symbol returns an error or empty result
- Payment failure via x402/USDC on Base results in 402 response blocking the call
- Binance API unavailability causes stale or missing kline data
- Malformed input schema (missing text or labels fields) returns a validation error
- Low confidence score may indicate ambiguous or ranging market conditions with no clear signal

## 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

Returns a JSON object with a classified label (e.g. trend regime or signal category), a rationale explaining the classification, and a confidence score between 0 and 1, derived from live Binance kline data and computed using a live trend-following bot's logic including Donchian channels, ATR stops, and backtests.
