Firefly Health

Firefly Health is a virtual-first primary care practice and clinically integrated health plan founded in 2016 and headquartered in Watertown, Massachusetts. Members get a dedicated care team - a primary care physician, nurse practitioner, health guide and behavioral health specialist - reachable by chat and video through the Firefly Health app, backed by the Firefly Nearby network for in-person, at-home and specialty care. Firefly sells an employer-sponsored alternative health plan alongside its virtual primary care service, and in 2025 became the first national primary care practice to earn NCQA Virtual Care Accreditation. Firefly publishes no public developer program, portal, documentation or specification: the member web and mobile apps are served by a private first-party API at api-prod.firefly.health under an /api/v2/ base path. Included Health signed an agreement to acquire Firefly Health in July 2026.

Firefly Health publishes 1 API on the APIs.io network. Tagged areas include Company, Healthcare, Health Plans, Virtual Care, and Primary Care.

Firefly Health’s developer surface includes signup flow, support, FAQ, engineering blog, YouTube channel, and 18 more developer resources.

scored 2026-09-14 · rubric v0.22.0
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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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/firefly-health: open an issue to ask a question, or submit a pull request to add artifacts.
