Packages

Substack — newsletter and subscription platform with an unofficial/limited API for post creation and subscriber management, primarily designed for human writers rather than programmatic agent publishing workflows.

PlayStation Network internal/unofficial REST API providing access to PSN player profiles, trophy data (bronze/silver/gold/platinum), game library, friend lists, and presence. Sony does not offer a public developer API; access is achieved through reverse-engineered endpoints used by the PSN mobile app and website, or via community libraries like the psn-api npm package.

Excalidraw is an open-source collaborative whiteboard tool with no public REST API. Integration is via embeddable React component or Excalidraw+ subscription. Agent automation is not supported via REST.
