No AK Steel host resolves; the successor site www.clevelandcliffs.com serves no developer documentation and therefore no published limits or rate-limit response headers. reconciled: true tags: - Steel - Manufacturing - Metals - Rate Limiting description: >- AK Steel Holding operates no public API and has not since the 2020-03-13 acquisition by Cleveland-Cliffs Inc., so there is no rate-limit policy, no documented quota, and no runtime rate-limit header to record. An honest zero. limit_count: 0 limits: [] headers: [] notes: >- CORRECTION 2026-08-30 — this file previously carried a synthetic "Not applicable" limits row written by the 2026-05-04 bulk sweep, and a responseCodes block asserting 429/503 behaviour for an API that does not exist. Both have been removed: nothing can be observed about the throttling behaviour of an endpoint that was never published. policies: - name: Successor entity description: >- Any integration request for former AK Steel product lines goes to Cleveland-Cliffs Inc., the successor entity, through its sales organisation.
