Show HN: Open-source library to unify Polymarket and Kalshi APIs
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.
- driver4567 8mo agoHi, nice project, just wondering is it battle tested, also in the repo, you say it can fetch data in seconds, I figure this is just a phrase, but seconds would be pretty slow, have you put in effort to make this fast?
