Companies reaching this through an API (28)

These companies publish an API, specification or operation carrying “OpenAI-Compatible” but do not classify their business under it. Listed unranked and kept out of the count above, because one tagged operation is not a statement about what a company does.

Cohort brief

The 38 providers in the APIs.io catalog tagged OpenAI-Compatible, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.

A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.

mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.
