API

ایک HTTP API جو صرف ہیش لیتی ہے۔ لاگ اِن کی ضرورت نہیں؛ ہر IP کے لیے 10 فی گھنٹہ اور 50 فی دن کی حد ہے۔

API کا حوالہ انگریزی میں ہے۔

WordPress plugin

Records a post's date every time you publish or update it. The plugin computes the SHA-256 of the post text on your own server and sends only the hash; the text and images never leave your site. Each update adds a new record, so the first publication is never overwritten. Version 0.1.1, GPLv2 or later, needs WordPress 5.8+ and PHP 8.2+.
