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 5 API contracts indexed on the APIs.io network, including Agent discovery API, Newsletter API, Onboarding API, and 2 more. Tagged areas include Healthcare, United States, e-Prescribing, Pharmacy, and Prescription Routing.

The Photon catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Photon’s developer surface includes documentation, API reference, getting-started guide, authentication, signup flow, engineering blog, sandbox, and 36 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Protected Resource Metadata +5 pts — a served /.well-known/oauth-protected-resource carrying `resource` (documented), and naming its authorization_servers (verified)
Agentic Commerce Well-Known Document +5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service, OR (0.27) a live x402 payment challenge from _data/x402-adoption.json — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's

2 more unmet checks in the Agent Readiness table above.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Life Sciences (Biotech and Pharma R&D)	undeclared	-	-	-
E-Prescribing (pharmacy, e-prescribing, medication data)	undeclared	-	-	-
US NPI Health Provider Registry (CMS NPPES)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
