DecisionsApi · Many models. One decision workflow.

DecisionsApiText in. Decisions out.

Explore decision models in one place. Compare Jev, Laya, Kev, Solar, and Span in the playground, then use one API to classify, score, and route text.

01 / Workbench

Decision workbench

Choose a task, edit the input, define typed questions, and preview the request before you connect the same workflow to your backend.

Unlimited free use in the online playground.

Workbench

What do you want to decide?

Choose a scenario to load editable input and rules. Loading an example uses no credits.

Examples load into the current draft only; no configurations or run history are saved.

State

Give the selected model the context shared by every question.

Text

All questions share this context and are answered independently.

Questions

Define up to eight typed questions for the same state.

3 / 8

3. Run decision

Run the decision request.

Result preview

Subject: Charged twice again!! Hi — this is the SECOND month in a row I've been billed twice for the Pro plan. I already emailed last month and nobody replied. I run my whole business on this. If it's not refunded today I'm cancelling and disputing the charge with my bank.

↓One input → multiple structured decisions

Click “Generate decisions” to see typed output with probabilities.

Results are returned in a structured format so you can connect them to your application logic.

02 / How it works

A decision is a useful interface for software.

Turn context and a bounded question into a result your code can inspect and use. The model provides the signal; your product controls the action.

01

Supply context

Provide a message, policy, record, or the application state the decision actually needs.

state = ticket.text
02

Define the question

Name the decision and its allowed answers, scale, or yes-and-no criteria.

questions = { intent, urgent }
03

Inspect the result

Read the typed answer, probability signals, model, usage, and request details together.

answer = result.answers.route
04

Choose the next step

Route, score, block, or request human review using the rules your application owns.

if result.urgent: escalate()

03 / Start from a real task

What you can build with Decisions API

Start with a decision your product already needs to make, then test clear and ambiguous examples before you automate the next step.

01

Route customer requests

Distinguish billing, technical, account, and other issues, then pass the selected label to your support system.

02

Choose an agent's next step

Classify whether a request needs a record lookup, a language model, a tool, or human review before anything executes.

03

Check claims against evidence

Place a claim beside a source passage and ask whether the supplied evidence supports, contradicts, or fails to establish it.

04 / Understand the output

How Decisions API turns context into an answer

Use a bounded question when your application needs a structured signal rather than another paragraph of generated text.

Choice

Select one label from a set you define. Use it for routing, categorization, filtering, and the next step in an agent workflow.

Score

Measure urgency, relevance, or completeness on an ordered scale whose boundaries are explicit and testable.

Noul / yes–no

Ask a focused yes-or-no question and use the returned probability with your own thresholds, rules, and review path.

Designed for developers

One Decisions API integration. Multiple models.

Move from the playground to your backend with the same state and question structure. Choose a supported model, send a server-side Bearer token, and receive structured answers with usage details.

05 / Understand the service

Start building with Decisions API

Testing credits included

New users receive credits for testing, so you can create an account, load an example, review the budget, and run your first questions.

One wallet for every live call

Use the same credit balance across the playground, API, and evaluation workflows. Credits from purchased packs do not expire.

Usage you can inspect

Review request history and credit activity, and use request identifiers to connect API calls with their usage records.

Pricing

Decisions API turns unstructured state into typed decisions with probabilities for classification, routing, scoring, and safety checks. Choose monthly, yearly, or one-time access for your usage.

One-time plans do not auto-renew or require a long-term subscription; the $10, $100, and $1,000 tiers include credits that remain available after purchase.

Important: Decisions API is currently in limited testing

Decisions API is not fully open yet and is currently available only for a small-scale test. Access will be enabled in payment order, and we’ll notify you by email. In the meantime, you can use Jev AI and other Decision APIs.
