What is Decisions API?
Decisions API is an independent playground and API for working with decision models from multiple providers. Choose from Jev 1.13, Liquid d1, Solar Decide, Tev1 4B Experimental, Kev 4B, Span-01, and Span-01 Lite. Submit text or JSON state with structured Choice, Score, or Noul questions, and get typed answers with probability or confidence information. The playground includes examples for support and agent routing, citation verification, content moderation, lead scoring, and LLM guardrails. Integrate from a server using a Bearer API key and POST requests to the SystemOne endpoint; documentation provides cURL, JavaScript, and Python examples. New accounts receive 100 credits. One-time credit packs start at $10, credits do not expire, and $1 buys 10,000 credits. Billing is based on model input usage, output tokens are not charged, and successful requests have a one-credit minimum.

Nail your distribution story before you finalize your feature set; judges and customers alike care more about reach than optimization.
When you raise prices it really helps. It's a much stronger signal to get people who really want to use your product.
Raising prices is a filter — it attracts customers who actually want the product
Cheap tiers attract tire-kickers and create margin pressure. Raising prices acts as a filter that selects for customers who genuinely value the product — usually fewer signups, but better ones with longer retention.
There's a play for whatever you're stuck on.
