Example prompt: Search Manifold Markets for prediction questions about the 2024 US presidential election and show me the top 5 results with their crowd probabilities and number of traders.

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates from Manifold Markets on any topic — especially for questions about future events, political outcomes, tech milestones, or news events. It is the right choice when the user wants prediction market data with trader activity metrics rather than a news summary or a single expert opinion. Prefer this over general web search when you specifically want quantified crowd probability with volume signals.

## Known failure modes

- Missing required 'q' query parameter returns an error
- Limit value outside 1-20 range may be ignored or cause an error
- No matching markets found returns an empty markets array
- Manifold Markets API unavailability causes upstream failure
- Very broad queries may return low-relevance results within the limit

## How this service works

Search Manifold Markets forecasting questions - crowd probability, volume, 24 hour volume, number of traders, close date, resolution state and link

## Output

A JSON object containing the interpreted query string, data source attribution, result count, and an array of market objects each with: question text, crowd probability as a percentage, total trading volume, 24-hour volume, number of traders, market type, creator username, creation time, close time (UTC), resolution status (boolean), and canonical market URL. An optional note field may provide context or caveats about the results.
