Jev AI Pricing & API Cost

Pay for input only — output is free. Start with $5–$20 to wire /api/v1/decide; move to Production ($100) when you leave staging. Tokens never expire while your account is active. Prepaid balance powers the hosted API and tools on jevtypesafe.org.

Hosted price is higher than raw upstream model rates ($0.042/M COGS) because you pay for instant access, prepaid metering, playground/tools/batch/editor, and keys that never expose upstream credentials. Larger packs show lower $/M.

Input tokens: $0.20–$0.42/M
Output tokens: Free
Per decision (avg): ≈$0.0004

How far each pack goes

At ~952 tokens per typical triage decision (≈$0.0004 at $0.42/M), here is the decide-call budget. Start small to wire the API — upgrade when traffic is real.

$5 Starter ≈ 12,500 typical /decide calls (wire + smoke test)
$100 Production and above unlock higher RPM + daily burn caps
Shorter state → more calls per dollar; multi-question calls share one round-trip

Decide-call comparison

Start with $5–$20; buy one step larger when you leave staging — unit price drops and limits rise.

Call the hosted decide API

After you prepay and create a jv_live_ key on Account, POST to /api/v1/decide. Same balance powers the ready-made tools.

curl

curl https://jevtypesafe.org/api/v1/decide \
  -H "Authorization: Bearer jv_live_YOUR_KEY_HERE" \
  -H "Content-Type: application/json" \
  -d '{"state":"Customer: my card was charged twice",
       "questions":{"topic":{"type":"choice",
         "instructions":"Route this message",
         "criteria":{"billing":"money","bug":"broken","account":"login"}}}}'

Python

import os, requests

r = requests.post(
    "https://jevtypesafe.org/api/v1/decide",
    headers={"Authorization": f"Bearer {os.environ['JEV_API_KEY']}"},  # jv_live_...
    json={
        "state": "Customer: my card was charged twice",
        "questions": {
            "topic": {
                "type": "choice",
                "instructions": "Route this message",
                "criteria": {"billing": "money", "bug": "broken", "account": "login"},
            }
        },
    },
)
print(r.json())

TypeScript

const r = await fetch("https://jevtypesafe.org/api/v1/decide", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.JEV_API_KEY}`, // jv_live_...
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    state: "Customer: my card was charged twice",
    questions: {
      topic: {
        type: "choice",
        instructions: "Route this message",
        criteria: { billing: "money", bug: "broken", account: "login" },
      },
    },
  }),
});
console.log(await r.json());

What that actually means

At $0.42 per million input tokens, a typical triage-style decision is about $0.0004 on published benchmarks. Output is free, so asking several questions in one call stays cheap.

1,000 decisions ≈ $0.40
1 million decisions ≈ $400
Anonymous visitors get 5 free real-API tool runs (no signup) — try before you buy
Registered accounts get ~10k free input tokens/month (smoke test, not production)
Create a jv_live_ API key on Account and call /api/v1/decide, batch, gate, or ready-made /api/v1/* — same prepaid balance as tools

What you are buying (and what you are not)

You buy prepaid capacity on this unofficial community host: instant jv_live_ keys, hosted decide/batch/gate, and ready-made templates — no official waitlist. You are not buying a TypeSafe SLA or raw upstream keys (those stay on our servers). We are not affiliated with TypeSafe AI.
