Penn Medicine
Penn Medicine is the University of Pennsylvania Health System (UPHS) plus the Perelman School of Medicine. It is an $11.9 billion enterprise powered by nearly 49,000 faculty and staff, operating six hospitals (Hospital of the University of Pennsylvania, Penn Presbyterian Medical Center, Chester County Hospital, Lancaster General Health, Princeton Health, and Pennsylvania Hospital — the first hospital in the United States, chartered in 1751) plus Penn Medicine at Home, Good Shepherd Penn Partners Rehabilitation, Lancaster Behavioral Health Hospital, and Princeton House Behavioral Health. The Perelman School of Medicine was awarded $580 million in NIH funding in fiscal year 2023. From an API perspective, Penn Medicine runs a production Epic-backed HL7 FHIR R4 endpoint at `https://ssproxy.pennhealth.com/PRD-FHIR/api/FHIR/R4` (Epic Organization ID 346, implementation description "University of Pennsylvania Health Systems FHIR Server"). The CapabilityStatement instantiates `us-core-server|6.1.0` and the HL7 Bulk Data Access IG, exposes 59 FHIR resource types covering Patient Access (clinical + claims) and Provider Directory per CMS-9115-F, and protects them with OAuth 2.0 / SMART-on-FHIR. Penn Medicine also operates the MyPennMedicine MyChart patient portal and the PhysicianLink referring-provider portal, and publishes open-source informatics work through several Perelman School of Medicine GitHub orgs (Penn-Medicine-CHCI, pennsignals, PMACS, pennbiobank).
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Penn Medicine the way a machine reads it — 50 machine-readable artifacts across 7 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Penn Medicine scores 59.5/100 (developing), with a separate agent-readiness read of 48/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Penn Medicine
Each block below is one kind of artifact we hold for Penn Medicine. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 7
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Open Collections 1
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

OPEN COLLECTIONPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Semantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.
Example request and response payloads for these APIs.
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
OAuth scopes governing access to this provider's APIs.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
