## When to prefer this

Use this endpoint when you have a canonical Predexon outcome ID and need to resolve it to its underlying market context or discover which prediction market venues (e.g. Polymarket, others) list it. Ideal for cross-venue aggregation, arbitrage discovery, or when navigating from a canonical ID to tradeable listings.

## Known failure modes
