Revnu Auth API is one of 2 APIs that [Revnu](https://apis.io/providers/revnu/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Authentication and Software-as-a-Service. The published artifact set on APIs.io includes authentication docs and API documentation.

The authentication API behind the @revnu/auth SDK, serving a Revnu store's buyers. Purchase-first — buying a product creates the account and sends a password setup link, so there is no separate sign-up flow. Identified by a publishable store key in the X-Revnu-Key header, and issuing RS256 JWTs whose claims embed the buyer's product entitlements, so access checks need no webhook and no callback.
