Every trade of the token pays a creator fee into an on-chain treasury. The treasury pays for the inference, so every call you make is free. No credits, no card, and you never need to hold the token.
No meter runs against your account. Trading volume on the token pays for the model, and the money moves on chain where anyone can check it.
Every buy and every sell pays a small creator fee.
One public wallet. The balance and every payment out are on chain.
Fees cover the model calls, so nobody has to buy credits.
Get a key, send your state, read a number. That's the whole deal.
Read straight from the running API and from chain. If a number here is wrong, the service is wrong.
Send one block of state and as many questions as you like. Answers come back as a named option, a position on a scale, or a probability. Never prose you have to parse.
{ "state": "You charged my card twice for invoice 402. I need the second charge refunded today.", "questions": { "team": { "type": "choice", "instructions": "Which team handles this?", "criteria": { "billing": "Charges, invoices, refunds", "shipping": "Deliveries and returns", "other": "Anything else" } } } }
Two to 255 named options. You get the pick, a probability for every option, and how concentrated that spread is. Concentrated is not the same as correct.
An ordered scale of two to ten levels. The answer is the probability-weighted mean, so it can land between two levels instead of pretending the scale is a list.
One probability that the answer is yes. Near 1 is yes, near 0 is no, and near 0.5 is real uncertainty. A confident no sits at 0, not in the middle.
Trading volume. Every trade of the token pays a creator fee into the treasury, and the treasury pays for the inference. You pay nothing.
No. Get a key and call. Holding or trading is never required to use the API.
Capacity follows volume. More trading buys more calls, and the board above shows what the treasury holds right now.
60 requests a minute per key, up to 64 questions per request, and three keys per address per day. The playground gives guests 20 calls an hour without a key.
Only a hash of each key is stored, so a key can't be shown again after it's issued. Keep it on your server, not in a browser.
Yes. Confidence tells you how concentrated the answer is, not whether it's right. Pick thresholds that fit what's at stake before you branch on it.
No. Jev is TypeSafe's model. usejev is an independent service that speaks the same request shape, and it isn't affiliated with TypeSafe or OpenJEV.
Run the live call above: the latency shown is measured from your browser to the API and back.
No sign-up, no card, no waitlist. Trading volume covers the bill.
