## 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 hedgehog-edge-crypto-indicator-signals-dfc256cd
```

Example prompt: Pull up the technical indicator signals for BTC/USD on Hedgehog Edge — I want to know if there's a golden cross, MACD bullish cross, or strong ADX trend as of yesterday.

## When to prefer this

Choose this endpoint when you need a quick boolean snapshot of multiple technical indicators for a specific crypto pair without computing them yourself. It's ideal for trading bots, signal-based automation, or screening workflows where you want to check several classic indicators (MACD, RSI, SMA200, Ichimoku, ADX, Bollinger Bands) in a single low-cost call. Prefer it over raw price data endpoints when your logic branches on indicator conditions rather than raw prices.

## Known failure modes

- Invalid symbol format — must be BASE/QUOTE (e.g. BTC/USD) and URL-encoded as BTC%2FUSD; returns 400 or error if malformed
- Unknown or unsupported trading pair — may return null values or error if the symbol is not tracked
- Date out of range — requesting a future date or one with no market data may return nulls or error
- Payment failure — x402 micropayment not completed results in 402 response and no data returned
- Missing required symbol path parameter returns 404 or bad request

## How this service works

## Output

A JSON object with boolean (or null) fields for each technical indicator signal: tk_cross, bb_squeeze, golden_cross, kumo_breakout, adx_strong_trend, rsi14_overbought, macd_cross_bullish, and price_above_sma200. Each field is true if the condition is active, false if not, or null if data is unavailable.
