## How to call it through Zero

```sh
zero fetch --capability signalpulse-prediction-market-scanner-ec325161
```

Example prompt: Scan all active prediction markets across Polymarket, Kalshi, Manifold, and PredictIt right now and tell me which ones are most mispriced — I want to see the cross-venue divergence, any whale flow signals, and your calibrated probability edge for each.

## When to prefer this

Choose this endpoint when you need a cross-venue, superforecaster-calibrated read of prediction markets with explicit edge quantification and whale-flow signals. It is preferable over raw market data APIs because it synthesizes Polymarket, Kalshi, Manifold, and PredictIt into a single actionable analysis with base-rate priors and sportsbook de-vigging for sports markets. Best when looking for arbitrage or mispricing across venues.

## Known failure modes

- No active markets found matching the query — returns empty result set
- Payment failure via x402 — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
- Venue data unavailable — partial results with caveat noting missing venue
- Invalid query parameters — returns 400 Bad Request

## How this service works

Calibrated superforecaster read of prediction markets across Polymarket, Manifold and PredictIt: cross-venue divergence, order-book/whale flow, base-rate priors, and for sports the de-vigged sportsbook consensus plus proprietary team-strength and weather engines. Full analysis, probabilities, edge and commentary on every mispriced market — props included.

## Output

A full analysis report covering active prediction markets across multiple venues, including calibrated probability estimates, identified mispriced markets, cross-venue divergence signals, order-book and whale flow insights, base-rate priors, de-vigged sportsbook consensus where applicable, and commentary on each notable edge opportunity — with props included.
