## 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 nexus-aggregate-financial-signal-cf997d04
```

Example prompt: What's the current NEXUS aggregate consensus for BTC right now — is it bullish or bearish, and how confident is the signal?

## When to prefer this

Use this endpoint when you need a single consolidated market sentiment signal for a cryptocurrency that combines technical indicators (z-score, Bollinger bands), AI model output, and prediction market data (Kalshi) into one confidence-weighted consensus — rather than querying each data source individually.

## Known failure modes

- Unknown or unsupported ticker symbol returns error or empty sources
- Network timeout from underlying data providers results in partial or failed response
- Payment not settled via x402/USDC triggers 402 Payment Required before data is returned
- Missing required 'symbol' query parameter returns validation error

## How this service works

Pay-per-call financial data. Streamable HTTP MCP. x402 USDC on Base. Not financial advice.

## Output

A JSON object containing the ticker symbol, current price in USD, a consensus label (e.g. BULLISH or BEARISH), a confidence score between 0 and 1, and sub-signals from multiple sources including z-score, Bollinger bands, Kalshi prediction markets, and a NEXUS AI model.
