## 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 nonvisceral-eloisa-mousily-ngrok-free-dev-16b3a7a2
```

Example prompt: What's the current gold XAU trading signal — is it bullish, bearish, or neutral right now, and what does the RSI-14 and 4-hour fib retracement say about where it's headed?

## When to prefer this

Use this endpoint when you need a ready-made, decision-grade gold trading signal with RSI and Fibonacci context in a single call — especially for automated trading agents that need no-KYC access to on-chain gold perpetual signals from Hyperliquid. Prefer over raw price feeds when you need pre-computed directional bias rather than raw OHLCV data.

## Known failure modes

- Upstream Hyperliquid data unavailable — stale or missing price data
- Payment not processed (402 error) — x402 USDC payment required before response
- Rate limit or ngrok tunnel downtime causing 5xx errors
- Signal computed from insufficient data window — RSI or fib context may be null

## How this service works

Gold XAU trading signal API: real-time gold price with directional signal (bullish, bearish, neutral), RSI(14) indicator, and 4h fib retracement context. Commodity and precious-metals market data for trading agents and automated strategies. Derived from Hyperliquid HIP-3 gold perpetuals — one of the few API sources for on-chain gold perp signals with no-KYC agent access.

## Output

Returns a JSON object with the current gold spot price, a directional signal string (bullish/bearish/neutral), RSI(14) value, 4-hour Fibonacci retracement context, a boolean indicating whether a trade is currently active, and a timestamp of last update.
