Photon

Photon Health is a United States prescription-infrastructure and e-prescribing (eRx) platform that lets digital-health companies embed prescribing, pharmacy selection, prescription routing, and fulfillment tracking into their clinical applications. Rather than an HL7 FHIR interface, Photon exposes a native GraphQL Clinical API - a single POST /graphql endpoint covering patients, prescriptions, orders, pharmacies, the medication/treatment catalog, drug-drug and drug-allergy screening, webhooks, and organization/user administration - plus a Patient Benefits API for pharmacy benefit checks and coverage. It also ships Photon Elements, prebuilt WebComponent UI for prescribing. The API is secured with OAuth2 client-credentials (Auth0) using machine-to-machine and user access tokens and prescription/order scopes; a sandbox runs on neutron.health. Photon serves prescribers and pharmacy-innovation partners including Amazon Pharmacy, Sesame, WeightWatchers, and Found.

Photon publishes 1 API on the APIs.io network: Website API. Tagged areas include Healthcare, United States, e-Prescribing, Pharmacy, and Prescription Routing.

The Photon catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Photon’s developer surface includes documentation, API reference, getting-started guide, authentication, signup flow, engineering blog, sandbox, and 35 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.
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/. This rating is computed from github.com/api-evangelist/photon: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
