Example prompt: What are the current prediction market odds on Trump winning the 2024 election — pull from all platforms and show me the Yes probability, 24h volume, and liquidity for each active market in the politics category.

## When to prefer this

Use this endpoint when you need current crowd-sourced probability estimates on future events, especially when you want cross-platform aggregation rather than a single exchange's odds. Ideal for elections, macro events, crypto price targets, and sports outcomes where prediction market consensus is more informative than polls or pundit opinion.

## Known failure modes

- No active markets found for the given topic or search query — returns empty results
- Invalid category filter value returns a validation error
- Platform filter specifies an unsupported or unavailable platform
- Market data temporarily unavailable due to upstream platform outage
- Payment failure (insufficient USDC balance) blocks the request

## How this service works

Live prediction market probabilities aggregated across multiple platforms. Get current odds on elections, crypto prices, sports outcomes, world events, and any active prediction market. Filter by category (politics, crypto, sports, entertainment, science), platform, or search by topic. Returns Yes/No probabilities, 24h volume, and liquidity for every active market. Powered by PROWL cross-platform data collection. Use this to answer 'what are the odds of X happening?' or 'what do prediction markets say about Y?'
