Companies reaching this through an API (4)
These companies publish an API, specification or operation carrying “HCM” 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.

Facet averages, against the whole catalog

|---|---|---|---|---|
| Contract Quality | 34.7 | 17.6 | +17.1 | 30 |
| Operational Transparency | 26.7 | 13.7 | +13 | 30 |

| Discoverability | 65.7 | 58.1 | +7.6 | 30 |
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.
