Show HN: Layer – One API for Polymarket and Kalshi

Hi HN, I'm David. I built Layer, an API + SDK or building trading bots/ai agents across prediction markets. The idea came from something i kept running into while playing with trading bots. Once your bot needs access to more than 1 venue, you suddenly have to deal with different market schemas, contract definitions, prices, fees and APIs before you can reason about where to trade. That gets messy
