generated: '2026-09-06' method: probed source: live probe of the named /.well-known path list plus /apis.json and /apis.yml note: env0 rebranded to "env zero"; the web and docs properties moved to envzero.com. Every host the record knows was probed. The only real document served anywhere on this provider's /.well-known/ surface is the A2A agent card on docs.envzero.com. No security.txt, no OAuth/OIDC discovery, no api-catalog, no apis.json. app.env0.com is a single-page-app catch-all that answers 200 with the same HTML shell for every path including a random control, so nothing there is recorded as a document. hosts: -
