## What an agent should know first

There is nothing here to call. As of 2026-09-06 Celanese exposes **no REST API, no GraphQL
endpoint, no MCP server, no A2A agent card, no webhook or event surface, and no published
OpenAPI, AsyncAPI, WSDL or Protobuf contract**. Do not attempt to construct a base URL from
the corporate domain: `api.celanese.com` does not present a matching certificate, and
`developer.celanese.com` and `developers.celanese.com` do not resolve.

## Human-facing surfaces

- [Celanese corporate site](https://www.celanese.com): Company, products, applications and
  investor information. Sitecore-backed React application behind an Akamai edge.
- [Chemille digital materials assistant](https://materials.celanese.com): Natural-language
  material-selection assistant that helps engineers find a plastic or polymer by property,
  application and certification. A browser application for people — it publishes no API,
  no OpenAPI and no MCP endpoint.
- [Celanese on LinkedIn](https://www.linkedin.com/company/celanese): Company updates.

## What API Evangelist measured

- `well-known/celanese-well-known.yml` — no security.txt, OpenID/OAuth metadata, api-catalog,
  ai-plugin or agent card on any Celanese host. Two paths reached the origin and returned a
  genuine 404; the remainder were answered by an Akamai catch-all 403 that a control probe
  showed is also returned for paths that simply do not exist.
- `packages/celanese-packages.yml` — zero first-party client libraries across npm, PyPI,
  RubyGems, crates.io, NuGet, Maven Central and Packagist. The GitHub organization
  `Celanese` exists but publishes zero public repositories.
- `plans/celanese-plans-pricing.yml` — zero published API plans.
- `rate-limits/celanese-rate-limits.yml` — zero published rate limits.
- `security/celanese-domain-security.yml` — celanese.com serves TLS 1.3, publishes SPF and a
  DMARC record at `p=none`, and has no HSTS header, no DNSSEC and no CAA record.

## Optional

- [Radix and Celanese industrial-data partnership](https://www.radixeng.com/post/radix-and-celanese-partnership-leverages-ai-to-harness-the-power-of-industrial-data):
  Context on Celanese's manufacturing-data work.
- [Cognite Data Fusion case study](https://www.cognite.com/en/customers/celanese): Celanese's
  internal manufacturing data platform. Internal to Celanese; not a surface a third party can call.
- [USEReady on Chemille](https://www.useready.com/press-release/useready-powers-chemille-an-ai-driven-digital-assistant-for-intelligent-materials-discovery-at-celanese):
  How the Chemille assistant was built.
