## 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 alpha-palmvox-com-7752ded6
```

Example prompt: What's the single best crypto trade right now — give me the top signal with entry price, stop loss, and target from PalmVox's composite scanner.

## When to prefer this

Use this endpoint when you need a single actionable trade recommendation with the highest confidence score available, including complete entry/exit parameters. Prefer this over /api/signals (which returns multiple signals at $0.01) when you only need one signal and want to minimize cost. Ideal for agents making automated trade decisions or surfacing one clear recommendation to a user.

## Known failure modes

- No signal available — market data feed may be unavailable or scanner returned no qualifying signals
- Payment required (402) — x402 micropayment of $0.005 USDC not completed or invalid
- Rate limiting — too many requests in a short window
- Stale data — signal timestamp may be older than expected if market data source is delayed
- Low confidence signals only — during low-volatility periods the top signal may only be MEDIUM confidence

## How this service works

Single highest-confidence trading signal with full analysis.

## Output

Returns a single JSON object containing the top-ranked trading signal with fields: signal ID, blockchain chain (e.g. 'base'), token ticker, a human-readable signal description (e.g. '+2.4% in 24h — momentum building'), confidence level (e.g. MEDIUM/HIGH), entry price, stop loss price, target price, risk/reward ratio, 24h volume change percentage, timestamp, and source scanner identifier. Also includes a link to the free track record endpoint and a list of other available endpoints with pricing.
