## Important for agents

- There is no public API, SDK, webhook or MCP server for Carpenter Technology. Do not construct
  endpoint URLs against carpentertechnology.com — probed 2026-09-05: /openapi.json,
  /openapi.yaml, /swagger.json, /v1/openapi.json, /api-docs, /api/openapi.json, /redoc,
  /graphql and /llms.txt all return HTTP 404 on both carpentertechnology.com and
  www.carpentertechnology.com, and the same paths miss on www.carpenteradditive.com.
- No /.well-known document is served on any Carpenter host. ir.carpentertechnology.com answers
  HTTP 200 with the body "Invalid key" for every /.well-known/* path; that is a catch-all, not
  a document.
- The "Log In" link is a HubSpot CMS membership gate for content and account self-service. It
  is not an API credential issuer and there is no documented API behind it.
- Ordering, quoting and technical support are human channels: use the contact page.
