## 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 clinkagent-prediction-market-odds-comparison-1e71b1a2
```

Example prompt: What do Polymarket and Kalshi currently say about the probability that the Fed cuts rates in September? Include the 24h and 7d moves and flag any gap between the two platforms.

## When to prefer this

Choose this endpoint when you need a structured, agent-ready summary comparing Polymarket and Kalshi odds side-by-side for any question — it does the matching, probability extraction, cross-platform gap calculation, and summarization in one call. Use /pm/search instead if you only need a raw list of matching markets without the analysis layer. Prefer this over manually scraping either platform or calling them separately.

## Known failure modes

- No matching market found on either platform — returns empty or low-confidence results
- Ambiguous question maps to unrelated markets — caller should rephrase or narrow the query
- Market data may be slightly delayed relative to real-time trading activity
- Kalshi or Polymarket API outage causes partial results for one platform
- Very niche or obscure questions may return no meaningful matches

## How this service works

What do the prediction markets say? Pass a question, get a finished read an agent can use directly: the best-matching market on Polymarket and on Kalshi with implied probability and 24h/7d moves, the cross-platform gap in points, a 7-day price history, a one-sentence summary, plus the top matching markets. Forecasting, research grounding, news context, event risk. ?q=<question>. Raw list only: /pm/search $0.01.

## Output

Returns the best-matching Polymarket market and Kalshi market for the query, each with implied probability, 24-hour and 7-day price moves, a cross-platform probability gap in percentage points, a 7-day price history array, a one-sentence human-readable summary, and a list of the top matching markets across both platforms.
