API registry / Manatal
Manatal
developers.manatal.com is a ReadMe site that lists OpenAPI definitions (manatal-open-api.json, manatal-career-page-api.json, manahook.json), but their registry entries return 404 and the site rate-limited direct file paths, so no verified URL is listed. The Open API base is https://open.manatal.com/open/v3.
Apideck doesn't connect Manatal yet, so its tools aren't available to your agent here. It's listed for its spec.
Manatal publishes no machine-readable API spec.
