Color

Color Health is an oncologist-led virtual cancer care company that provides screening, early detection, diagnosis, treatment guidance, and survivorship support to employers, health plans, unions, consultants, and public-sector organizations. Originally founded as a genomics testing company (Color Genomics), Color now operates a virtual clinical platform combining at-home testing kits, preventive health programs, and AI-assisted cancer care. For integration partners Color publishes an External API V1 at api.color.com/api/v1/external — 13 operations across eligibility entries, population reporting (participants, samples, results, self-reported results) and a lab/LIMS sample lifecycle — documented at docs.color.com/reference, alongside SAML-based SSO and SFTP/PGP file transfer for eligibility, claims, and member-event data.

Color publishes 3 APIs on the APIs.io network: Eligibility API, Populations API, and Samples API. Tagged areas include Company, Health, Healthcare, Genomics, and Oncology.

Color’s developer surface includes documentation, API reference, getting-started guide, changelog, engineering blog, signup flow, support, and 28 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/color: open an issue to ask a question, or submit a pull request to add artifacts.

  note: Found and captured Color's real published OpenAPI (13 operations) via the ReadMe API registry the docs reference renders;
    the previous round carried a 1-operation spec hand-reconstructed from prose. Removed a WellKnown pointer that was backed
    by an all-404 probe, and did not emit SDKs, RateLimits, Pricing, Roadmap or StatusPage pointers because none of those
    surfaces exist.
