Penn Medicine Rate Limits

Machine-readable rate-limit scaffold for the Penn Medicine FHIR R4 API. UPHS does not publish formal per-key rate-limit numbers; the values below capture the Epic platform's typical patient-app and backend-services governance behavior plus the underlying HL7 Bulk Data Access IG semantics. Real limits are confirmed during app registration / data-sharing agreements.

Penn Medicine Rate Limits is the machine-readable rate-limit profile for Penn Medicine on the APIs.io network, in the API Commons Rate Limits shape.

It captures 3 rate-limit definitions, across the patient-access, provider-directory, and bulk-data tiers, measuring requests_per_minute and concurrent_jobs.

Limit state is signalled in the retryAfter response header, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled and serviceUnavailable.

Tagged areas include Healthcare, Hospital, FHIR, Rate Limiting, and Throttling.

Policies

Backoff Strategy
Clients should implement exponential backoff with jitter, honoring the Retry-After header when present.
Bulk Export Polling
Per the HL7 Bulk Data Access IG, clients poll the Content-Location URL using Retry-After hints; aggressive polling will be throttled.
Patient Consent
All patient-context reads require an active OAuth access token; revoked tokens immediately stop returning data regardless of rate limits.
Fair Use
Sustained traffic that materially impacts UPHS clinical operations may be throttled or revoked outside the documented limits.
