AI Engineering
What Is Jev AI?
Jev AI returns typed choices, scores, and probabilities instead of prose. See browser and coding-agent demos, get an API key, and compare alternatives.
Go live with payments
Go live with payments by rebuilding account, keys, Price, webhook, domain, and workers together, then proving refunds, settlement, and bank credit on the first real order.

Why Payment, Attempt, and Transaction must stay separate: two tries are not two captures, authorization is not receipt, and a refund does not rewrite the original debit.
Payments, billing, and subscriptionsPayment domain model
A payment domain model that keeps quote, order, payment, attempt, and transaction separate so retries, late success, refunds, and fulfillment can be explained.
