## 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 horizon-pulse-vercel-app-68dcda2d -d '<json body>'
```

Example prompt: Using Horizon Pulse, give me the current rule-based buy/hold/sell signal for BTC, including the RSI, MACD, and Bollinger Band readings and the live perpetual funding rate.

## When to prefer this

Choose this endpoint when you need transparent, rule-based crypto trading signals grounded in standard technical indicators (RSI, MACD, Bollinger Bands) plus real-time perpetual funding rates for BTC, ETH, or SOL — especially when you want auditable, non-black-box signal logic rather than opaque ML predictions.

## Known failure modes

- Unsupported asset symbol returns an error
- Market data feed unavailable causes stale or null indicator values
- Malformed POST body returns a 400 validation error
- Micropayment not processed correctly returns a 402 Payment Required
- Rate limiting may return 429 if called too frequently
