## How to call it through Zero

```

Example prompt: Scan Polymarket and Kalshi right now for any arb opportunities on US election contracts — show me the both-leg strategy, gross cost, Kalshi taker fee, net edge, and whether each match is an ARB_CANDIDATE, CONVERGENCE_GAP, or ALIGNED.

## When to prefer this

Use this endpoint when you need to identify cross-venue prediction market arbitrage between Polymarket and Kalshi specifically, with deterministic fee-adjusted net edge calculations and structured verdicts. Prefer this over general financial arbitrage endpoints when your focus is prediction market event contracts rather than crypto, ETFs, or sports books.

## Known failure modes

- No contracts found matching the query topic — returns empty results
- Stale or unavailable order book data from Polymarket or Kalshi — may return partial results
- Invalid query parameter format — returns 400 error
- Payment not processed — returns 402 Payment Required
- Rate limiting or service unavailability — returns 5xx error

## How this service works

Prediction market cross-venue arbitrage — matches live Polymarket contracts to Kalshi contracts for the same events: both leg strategies, gross cost, Kalshi taker fee, net edge per contract, ARB_CANDIDATE / CONVERGENCE_GAP / ALIGNED verdicts. Optional ?query= topic filter. Deterministic order-book math, no LLM.

## Output

A list of matched Polymarket/Kalshi contract pairs for the same event, each with the both-leg trade strategy, gross cost, Kalshi taker fee, net edge per contract, and a verdict of ARB_CANDIDATE, CONVERGENCE_GAP, or ALIGNED. Computed using deterministic order-book math with no LLM involvement.
