## 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-c65bc94f -d '<json body>'
```

Example prompt: What are the current RSI, MACD, and Bollinger Band readings for BTC, and is the rule-based signal showing buy, hold, or sell right now?

## When to prefer this

Use this endpoint when an AI agent needs rule-based, transparent technical analysis signals (RSI, MACD, Bollinger, funding rates) for BTC, ETH, or SOL — especially when the agent must explain its reasoning and cannot use black-box ML predictions. Ideal for automated trading decision support, portfolio monitoring workflows, or any scenario requiring live momentum data with explicit buy/hold/sell verdicts.

## Known failure modes

- Unsupported symbol returns an error — only BTC, ETH, SOL are supported
- Upstream exchange data unavailable causes stale or error response
- Payment not received or invalid x402 auth results in 402 Payment Required
- Network timeout if real-time price feed is delayed

## How this service works

## Output

Returns real-time technical indicator values (RSI-14, MACD 12/26/9, Bollinger Bands 20/2) alongside live perpetual funding rates and a transparent rule-based buy/hold/sell signal for the requested crypto asset (BTC, ETH, or SOL).
