API for Any Site
An open-source Chrome extension lets AI agents operate websites through browser-based APIs, including sites that never provided one.
Field notes
The extension turns website interactions into site-specific tool calls that an agent can invoke through the user’s own browser session. The homepage shows LinkedIn and Reddit kits, plus a workflow for generating a Hacker News kit from a manifest and JavaScript files. It also describes per-site fences, isolated execution for user-written kits, action switches, logged calls, and configurable daily limits. The project presents the extension, runtime, and catalog kits as open source.
