Prediction market aggregator API
A prediction market aggregator API puts markets from several venues behind one schema, so you can compare prices and history without writing a client per venue.
What to check
- Which venues are covered, and how markets are matched across them.
- Timestamp source and delay on each tier.
- Historical depth and whether order books or only last prices are stored.
- Rate limits and redistribution rights.
