Healthcare and life sciences is one of the deepest verticals on the network. The Healthcare & Life Sciences industry tracks 376 providers publishing 1,296 APIs, spanning EHR integration, payor systems, telehealth, clinical-trial infrastructure, medical-device data, regulatory feeds, and the pharma and biotech research stack. It is a useful map precisely because “healthcare API” means a dozen different things depending on which corner you stand in.
Functional bands
| Band | Real providers on the network |
|---|---|
| FHIR platforms / EHR | Medplum, Canvas Medical, HL7 FHIR |
| Interoperability & data | Particle Health, Stedi |
| Devices & wearables | Dexcom |
| Billing & revenue cycle | Candid Health |
| Document & data intelligence | Affinda |
Those are not the whole list — they are entry points. Medplum is an Apache 2.0, FHIR-native developer platform. Canvas Medical is a developer-first EHR with a FHIR R4 API. Particle Health aggregates records across the nationwide health information exchanges. Stedi runs an API-first healthcare clearinghouse. Dexcom streams continuous glucose data off a medical device. Each one is a different integration problem wearing the same word.
What’s shifted recently
Three named patterns show up when you read across the providers.
FHIR went from checkbox to foundation. Platforms like Medplum and Canvas Medical are not bolting FHIR onto a legacy core — they are FHIR-native from the datastore up, exposing REST and GraphQL over R4 resources with SMART on FHIR auth.
The CMS interoperability mandate created a payor API wave. Insurers now publish FHIR R4 Patient Access and Provider Directory APIs to comply with the CMS-9115-F rule. That is why plans that never had a developer program are suddenly in the catalog with FHIR endpoints.
Ambient clinical AI became its own segment. A cluster of providers — Heidi Health, Suki AI, Corti, Amigo — build documentation and clinical reasoning from audio and text, a category that barely existed a few product cycles ago and now sits alongside the EHRs it plugs into.
Where to start
If you are building here, do not start from a vendor shortlist. Start from the Healthcare & Life Sciences industry page, filter by the band that matches your problem — interoperability, devices, billing, or clinical AI — and read the rated providers in that band before you commit. The industry view exists so you can see the shape of the space before you pick a name.
Takeaway
Healthcare on APIs.io rewards knowing which sub-problem you actually have. FHIR-native platforms, mandate-driven payor APIs, and ambient clinical AI are three different worlds sharing one industry label, and 1,296 APIs across 376 providers is a lot of surface to walk blind. Use the industry page as the map, then go deep on the two or three providers that match your integration, not the twenty that merely match the keyword.
