layahost is a hosted API for typed decisions. You send a piece of text and a question with a fixed set of answers - a choice, a yes/no or a score - and get back the answer with a probability for every option, as JSON your code can branch on. Use it for comment moderation and spam, support intent and routing, sentiment, priority and language detection, without prompting an LLM and parsing its output. It runs Laya, the open-source (Apache-2.0) decision model, and implements the wire format of the Jev System One API (POST /v1/systemone), so the official Jev Python and JavaScript SDKs work after you change the base URL and the key. Pricing is flat: $5 per million decisions regardless of text length, prepaid, hosted in the EU.
