Layer vs. NiubiGEO

One API for prediction markets. Find markets, stream normalized data, place orders, and track positions across Kalshi and Polymarket. 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 real fast, especially with prediction markets. The same real-world event can exist on Kalshi & Polymarket, but the contracts can be represented differently.Here's my broader thesis:...

NiubiGEO says it organises more than 150,000 people across communities, creator circles, launch sites and developer networks to test products, create content and spread the word, and it keeps checking whether a product is found in search and in AI assistants. It also publishes open-source AI brand-visibility and competitor reports. Paid services: testing by real people and GEO optimisation.
