## 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 x402-endpoints-cross-exchange-trading-signal-fusion-4d8b1d7a
```

Example prompt: What's the fused trading signal for ETH on the 1h timeframe right now — is the market crowded long or short, what's the funding bias, and should I go long or short based on the cross-exchange data from Binance, Bybit, OKX, and Hyperliquid?

## When to prefer this

Use this endpoint when you need a multi-factor, cross-exchange directional signal that fuses funding rate sentiment, crowding analysis, trend regime detection, and BTC lead-lag correlation into a single machine-readable verdict. Prefer this over raw exchange APIs when you want pre-computed, weighted signal fusion without building your own quant pipeline. Best for agents making pre-trade directional decisions on liquid crypto perpetuals (BTC, ETH, SOL, etc.) across Binance, Bybit, OKX, and Hyperliquid simultaneously.

## Known failure modes

- Symbol not supported on target exchanges — returns error or missing component data
- Timeframe enum value invalid — returns validation error
- Exchange API outage causes partial component availability — returns signal with reduced components
- No market data available for illiquid asset — returns null components
- Payment not processed (x402) — returns 402 Payment Required before any data

## How this service works

Crypto trading signal (long/short) and market-regime signal in ONE call: LONG/SHORT/NEUTRAL with confidence, fusing the cross-exchange funding rate, crowding (long/short) bias, trend/chop market regime and BTC→altcoin lead-lag from Binance/Bybit/OKX/Hyperliquid — with declared data freshness. Should I go long or short on this coin? A fused directional trading signal where competitors sell the funding rate, regime and the four numbers separately. Derivatives trading signal for any altcoin.

## Output

A JSON object containing: a directional verdict (LONG/SHORT/NEUTRAL), a fused score from -1 to 1, a confidence value (0-1), individual component votes and interpretations (regime/funding/crowding/lead-lag), the exchanges queried, timestamped data freshness metadata, and a list of weighted reason codes explaining the signal. Includes a disclaimer that this is not financial advice.
