Hi Product Hunt, I built Resvary because prepaid AI credits get complicated as soon as requests retry, overlap, fail, or report usage after the work finishes. A balance column cannot tell you which funds are available, which are reserved, or whether a retry should charge again. Resvary wraps each operation in a reserve, commit or release flow. It records immutable price versions and usage receipts, supports SQLite and PostgreSQL, and includes a worker and Operator Console for tracing balances and recovering failed operations. Keep Stripe or another payment rail for checkout and invoices. Resvary handles the credit authorization around each model or tool call. I publish Resvary under Apache-2.0. You can install the packages from npm and run the deterministic demo without an AI key. The agent demo also shows Testnet funding through Circle Gateway and Arc. I’d love feedback from teams already using prepaid credits or usage billing. Which failure cases have caused the most pain in your stack?
