How to get Jev
Jev's official access is waitlisted — but there are already several ways to start using it today. Here's every route, from fastest to most official.
Try it now — free playground
Run real Jev calls in your browser, no key and no signup. Best way to see what choice / score / noul return before you build.
Open the playground ▶Get a hosted API key (no waitlist)
Call Jev through our metered API: sign in, create a jv_live_ key, prepay a small balance, and hit /api/v1/decide. You skip the TypeSafe waitlist; we proxy to the real model and bill per input token.
Get an API key →Through a gateway / provider
Jev is listed on Vercel AI Gateway (typesafe-ai/jev), OpenRouter (typesafe/jev via its decisions endpoint) and Cloudflare AI Gateway — route to it with your existing gateway key.
See gateways →Official TypeSafe access
For production keys, quotas and billing straight from the source, join the waitlist and use the console + the /v1/systemone endpoint. This is the official route and the source of truth for pricing.
console.typesafe.ai ↗In your agent — MCP, Claude Code & LangChain
Give an agent Jev tools with jev-mcp (one npx line for Claude Code, Codex or Cursor), or call it from LangChain via langchain-typesafe / TypeSafeClassifier for routing, guardrails and context compaction.
Ecosystem & tools →jevtypesafeai.com is an independent site — not TypeSafe AI. The hosted key is our own metered proxy over the official API; for official access, quotas and the source-of-truth pricing, go to typesafe.ai.
