JEV API / HE JEV

JEV API connects your ideas with workflows.

JEV API is the integration direction for JEV decision and automation workflows. Explore how an application can frame a task, request a proposed action, and keep approval in human hands.

01 / JEV API / HE JEV

JEV API gives integration planning a shape.

Give your application a clear decision point. Define the context, review the proposed direction, and connect the result with the next step in your workflow.

JEV API planning starts with a task.

A JEV API integration starts with your application’s objective, relevant context, and permitted actions. Define those inputs before choosing an execution tool. Keep credentials outside the task brief.

JEV API planning defines a review point.

A proposed JEV API result should expose the next step and any missing information. Your application needs a validation contract so that an incomplete proposal cannot silently become an action.

Your application controls execution.

JEV API integration planning should separate a proposed action from permission to execute it. Your application records the outcome, handles errors, and asks for approval before a consequential change.

02 / FROM INTENT TO ACTION

JEV API planning separates proposals from actions.

JEV API integration planning starts before an endpoint is called. Use these conceptual examples to define inputs, expected results, and approval boundaries; they are not executable API documentation.

AN ILLUSTRATIVE WORKFLOW

Define the input contract.

THE CONTEXT

Your application supplies the objective, options, constraints, and a result format.

THE NEXT STEP

A proposed JEV API integration returns a reviewable proposal; your application validates it.

Define the browser approval boundary.

THE CONTEXT

Your application lists permitted pages and separates reading from changes.

THE NEXT STEP

A proposed JEV API integration requests an action; your application checks permission.

Define the publishing checkpoint.

THE CONTEXT

Your application supplies a campaign brief and keeps publishing credentials separate.

THE NEXT STEP

A proposed JEV API integration prepares a result; your team approves publication.

You review the direction.

INTEGRATION / FIELD TEST

JEV API examples show how to wire a decision layer.

These external integration notes concern TypeSafe's Jev API. They illustrate typed results and real application trade-offs; this page does not publish an HE Jev endpoint.

PLATFORM INTEGRATION · VERCEL

Call TypeSafe's Jev through AI Gateway

Vercel documents availability through its AI Gateway. Consult the provider's current model and pricing details before implementing; the surrounding application owns validation and side effects.

THIRD-PARTY FIELD TEST · RETRIEVER AI

Browser tasks got faster, but not cheaper

In two one-run comparisons, rtrvr reported 31% and 43% less elapsed time with Jev, but 38% and 51% higher total cost against its inexpensive cached baseline. These are observations, not a controlled benchmark.

OFFICIAL API QUICK START · TYPESAFE AI

Send support questions in one typed request

TypeSafe's quick start shows one state with Choice for department, Score for frustration, and Noul for urgency, plus the corresponding structured response and Python SDK call.

COMMUNITY RUNNABLE EXAMPLES · GITHUB

Try ticket triage and candidate re-ranking

A community repository includes tests and executable examples through OpenRouter. Its author verified that route, while the direct TypeSafe API path was written from documentation but not live-tested.

Inspect the example repository

An API decision is not permission to act. Applications must validate options, verify outcomes, and handle ambiguous or consequential cases before execution.
