## Known failure modes

## How this service works

Active prediction markets on Limitless Exchange (on-chain, Base; keyless). Each market: conditionId, title, slug, description, status, live YES/NO prices, volume, liquidity, collateral token, expiration, and categories/tags. A second venue alongside the Polymarket (predict.markets) and Kalshi (predict.kalshi-markets) clusters — for cross-venue prediction-market coverage.

## Output

A list of up to 50 active prediction markets from Limitless Exchange, each containing: conditionId, title, slug, description, status, live YES/NO prices, trading volume, liquidity depth, collateral token, expiration timestamp, and category/tag labels.
