From the developer

Matthias Pfefferle's own description of NodeInfo, lightly tidied.

NodeInfo is an effort to create a standardized way of exposing metadata about a server running one of the distributed social networks. The two key goals are being able to get better insights into the user base of distributed social networking and the ability to build tools that allow users to choose the best fitting software and server for their needs.

This plugin provides a barebone JSON file with basic “node”-informations. The file can be extended by other WordPress plugins, like OStatus, Diaspora or ActivityPub.

What information does this plugin share?

The plugin exposes the following public information about your site:

  • Software: WordPress version (major version only for privacy)
  • Usage statistics: Number of users, posts, and comments
  • Site info: Your site name and description
  • Protocols: Which federation protocols your site supports (e.g., ActivityPub)
  • Services: Which external services your site can connect to (e.g., RSS feeds)

This information helps other servers in the Fediverse discover and interact with your site.

Supported NodeInfo versions

This plugin supports all major NodeInfo specification versions:

  • NodeInfo 1.0 and 1.1 – Original specifications
  • NodeInfo 2.0, 2.1, and 2.2 – Current specifications with extended metadata
  • NodeInfo2 – Alternative single-endpoint format

Endpoints

After activation, the following endpoints become available:

  • /.well-known/nodeinfo – Discovery document (start here)
  • /wp-json/nodeinfo/2.2 – NodeInfo 2.2 (recommended)
  • /wp-json/nodeinfo/2.1 – NodeInfo 2.1
  • /wp-json/nodeinfo/2.0 – NodeInfo 2.0
  • /wp-json/nodeinfo/1.1 – NodeInfo 1.1
