Hey everyone! I built Telonex because I needed clean prediction market data for my own research and couldn't find it anywhere. Polymarket has become one of the most interesting financial markets in the world, but getting historical data meant scraping APIs, managing WebSocket connections, and dealing with messy blockchain data. I figured if I was spending weeks just cleaning data instead of actually analyzing it, others were too. So I built the infrastructure to collect, normalize, and serve tick-level trades, order books, quotes, and onchain fills - all in clean Parquet files ready for analysis. Would love to hear what you'd build with this data!
