I noticed prediction markets are becoming fragmented (Polymarket on-chain, Kalshi regulated/off-chain), making it painful to write cross-exchange bots. Crypto has ccxt to standardize exchange APIs, but nothing existed for prediction markets.

I built pmxt to solve this. It normalizes the data across platforms so you can treat them as a single liquidity source.

It’s open source and I'm looking for feedback on the API structure before I start adding execution/trading endpoints.
