WordPress plugin for content provenance

Auto-sign every article on publish and embed a verification badge readers can check. We're finalizing the WordPress.org submission — join the waitlist to be notified when it's available.

How it works

Author publishes article

The WordPress publish hook triggers the AxIA Protocol plugin automatically.

Compute SHA-256 hash

The plugin hashes the article content (HTML body + featured image) locally.

Sign via Axia API

The hash is sent to POST /sign with the site's API key. Ed25519 signature and Merkle proof are returned.

Store proof as post meta

The signature, hash, and proof URL are stored as WordPress post metadata.

Embed verification badge

The <axia-verify> widget is automatically injected into the article footer.
