01 · Overview

What it is

apisloth watches OpenAPI specifications and API documentation, records structured changes, and follows the repositories that depend on them. Breaking changes, repository context, automation runs, and open pull requests become queryable from Claude Code or Codex. The action tools let your agent add a source, connect a repository, or stop a watcher from the same conversation.
