## 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 aizamon-mid-loop-venue-match-0a33d086
```

Example prompt: Which prediction market platform — Polymarket or Kalshi — has the best venue for 'US recession 2025', and what's the price gap between them?

## When to prefer this

Choose this endpoint when you need a quick, mid-loop lookup to identify the optimal venue (Polymarket vs Kalshi) for a specific prediction market topic and want a bucketed gap summary — rather than a full arbitrage pack or raw spread. It is the right choice when cost efficiency matters ($0.05 vs $0.89 for the full pack) and you only need the top match for one query at a time, not the top-5 fee-adjusted spread cards.

## Known failure modes

- No matching market found on either platform for the given query — returns empty or null venue
- Query too vague or ambiguous to resolve to a specific market
- Payment of $0.05 USDC not settled — request rejected before processing
- Rate limit or spend cap exceeded under default $0.10 spend cap
- Stale or unavailable market data if either exchange API is temporarily down

## How this service works

Mid-loop venue match — $0.05. Pass ?q= market topic; get best Polymarket↔Kalshi venue + bucketed gap for that query. Under default $0.10 spend caps.

## Output

Returns the best-matching Polymarket or Kalshi market for the given topic query, along with a bucketed representation of the yes-price spread (gap) between the two venues at the time of the call.
