Rewrite API for Hidden-Character Cleanup

Base URL: https://aitextwatermarkchecker.com/api/v1. Authenticate with Authorization: Bearer <key> after you create a key in your account.

What the API is

POST /scan runs the same character rules as the browser tool and returns findings plus cleaned text. It does not call a model. POST /rewrite would change wording when Rewrite is enabled and billed; in v1 it returns that Rewrite is not available yet and does not call a model.

How billing would work

Scan costs 0. Rewrite would charge by output words (1 credit = 100 words) against Pro balance when payments and rewrite are enabled. See API Docs and Pricing.
