# H1 **Canonical:** https://apis.io/providers/h1/ **Website:** https://h1.co/ **APIs profiled:** 21 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. ## Kin Score — 54.3 / 100 (strong) Scored 2026-08-20 under rubric 0.12.0.
