H1

H1 (h1.co) is a New York City-based healthcare data and technology company, founded in 2017, that combines deep healthcare provider data with agentic AI to power drug development, medical and commercial engagement, care navigation, and provider and network intelligence for life sciences, pharma, health plans, and digital health organizations across the United States. Its developer-facing API is the Ribbon Health API (H1 acquired Ribbon Health), a proprietary REST API served over HTTPS at https://api.ribbonhealth.com that provides accurate, comprehensive data on healthcare providers, locations, insurances, procedures, price transparency, cost estimates, and insurance eligibility. Two OpenAPI 3.1 contracts are published - the 75-operation v1 API under /v1, and a newer 7-operation location-first Price Transparency v2 surface under /v2 that H1 tells new integrations to prefer over the legacy provider-first /v1/pricing endpoints. The API is not FHIR-based and does not expose a SMART-on-FHIR or Da Vinci PDEX Plan-Net surface; it authenticates with a bearer API key, has no OAuth scopes, and gates product families on per-account entitlement flags. It is segmented into provider, location, custom-filter, focus-area, price-transparency (v1 and v2), cost-estimate/eligibility, organization, reference-data, and network-analysis product families. Access is gated behind a request-demo / API-key sign-up rather than fully self-serve, and no pricing, plans, SDKs, sandbox, changelog or webhook surface is published.

H1 publishes 12 APIs on the APIs.io network, including Cost Estimates API, Filters API, Focus Area Endpoints API, and 9 more. Tagged areas include Healthcare, United States, Life Sciences, Provider Data, and Healthcare API.

H1’s developer surface includes authentication, documentation, API reference, getting-started guide, signup flow, engineering blog, support, and 39 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/h1: open an issue to ask a question, or submit a pull request to add artifacts.
