## When to prefer this

Use this endpoint when you need historical resolved market data — to verify whether a predicted event occurred, evaluate prediction market accuracy, or backtest trading strategies. For live/current odds use the live markets endpoint instead. Best when the user asks 'did X happen?' or wants to review past outcomes rather than current probabilities.

## Known failure modes

- No markets found matching filters — returns empty result set
- Invalid date range or filter parameters — returns 400 validation error
- Platform or category filter not recognized — returns 400 error
- Service unavailable or data feed lag — returns 503
- Payment not processed — returns 402 payment required

## How this service works

Useful for backtesting strategies, verifying claims about past events, or tracking platform accuracy. Powered by PROWL. Use this to answer 'did X happen?' or 'what prediction markets resolved recently?'

## Output

A list of recently resolved prediction markets including market title, the correct outcome (Yes/No or specific result), the final probability/odds just before resolution, resolution timestamp, trading platform, 24h volume near resolution, and whether the market resolved as expected.
