How to get a Jev API key

Getting a Jev API key takes two minutes. You can join the official TypeSafe waitlist, or skip the line entirely with our hosted Jev API key that works the moment you sign in.

Two ways to get a Jev API key

There are two routes to a working Jev API key. The official route runs through TypeSafe AI, the team that built Jev. The independent route runs through this site, which offers a hosted, metered Jev API key with no waitlist. Both give you the same typed decisions; they differ only in how fast you can start and how you are billed.

The official TypeSafe route

To get the official Jev API key, join the waitlist at typesafe.ai. Once you are approved, you can create your Jev API key in console.typesafe.ai and call the model directly.

• Join the waitlist at typesafe.ai and wait for approval.
• Generate your key in console.typesafe.ai.
• Send requests to POST https://api.typesafe.ai/v1/systemone.
• Authenticate with the header Authorization: Bearer <key>.
• Official SDKs read the key from the TYPESAFE_API_KEY environment variable.

The hosted route with no waitlist

If you do not want to wait, this site issues a hosted Jev API key instantly. Sign in, add a small prepaid balance on the pricing page, and you receive a jv_live_ key you can use right away. Your hosted Jev API key routes through our metered proxy, so you get the same choice, score, and noul decisions without any approval step.

How to authenticate and store your key

Whichever Jev API key you use, keep it secret. Never commit a key to git or paste it publicly. Store your Jev API key in an environment variable and read it at runtime.

With the hosted key, send requests to POST https://jevtypesafeai.com/api/v1/decide and set the header Authorization: Bearer jv_live_ followed by your key.

What a Jev API key costs

Jev is priced per input token, and output is free. The official rate is $0.042 per million input tokens, which works out to roughly $0.0004 per decision. On the hosted route you prepay a small balance and are billed the same way, per input token with output free, so a single Jev API key can cover thousands of calibrated decisions for a few cents.
