Optio

Optio is a developer API that returns decisions you can build on. Send a question and a set of options and get back a choice, a score, or a yes/no answer together with calibrated probabilities, so your application knows not just what the model picked but how confident it is. The API is a drop-in /v1/systemone endpoint that you can call from any language with a simple HTTP request. A free playground on the website lets you try the decision model in the browser before writing any code. There is no waitlist: sign up, get credits and start calling the API right away, then pay as you go with credits when you scale. Optio is built for developers, startups and product teams who want to add decision-making, ranking, triage or approval logic to their apps without training and hosting their own models.

What problem it solves

Developers who need reliable yes/no, choice and scoring decisions with probabilities they can trust, without building their own model.
