Product documentation

Audiobook Narration API

Produce consistent narration for text the customer owns or licenses. This focused audio engine template defines one documented request contract, an enforceable package, and locked technical settings. It remains unavailable for purchase until UrTheProduct verifies an exact provider mapping, rights, reliability, cost ceiling, and final price.

This page is the public integration contract. Purchase is enabled only when the exact provider, cost ceiling, final price, and Whop plan are approved; internal prompts and provider details are never part of the public request.
