Smarthealthit Rate Limits

SMART Health IT does not publish numeric rate limits for its public sandboxes. The open FHIR servers (r2/r3/r4.smarthealthit.org), the SMART App Launcher, and the reference Bulk Data server are free shared test infrastructure operated for the developer community; capacity is governed by fair use rather than documented per-key quotas, and there are no accounts or API keys to meter against. The Bulk Data server exposes its own pacing controls - the async $export pattern returns 202 with a status URL and clients are expected to honor Retry-After when polling - and its simulated database size, file pagination, and error rates are configurable per test server instance.

Smarthealthit Rate Limits is the machine-readable rate-limit profile for SMART Health IT on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring requests, launches, and patients.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include SMART on FHIR, FHIR, Health IT, Sandbox, and Rate Limiting.

Limits

Open FHIR Sandbox Requests anonymous
requests
not published
No documented numeric limit; shared fair-use test infrastructure with no API keys.
SMART App Launcher Sessions anonymous
launches
not published
Launch simulations and OAuth flows are unmetered; no client registration exists to meter against.
Bulk Data Export Polling client
requests
honor Retry-After
The $export status endpoint follows the FHIR async pattern; clients must poll politely and honor Retry-After headers.
Bulk Data Simulated Database server-instance
patients
configurable up to 1,000,000
Each generated Bulk Data test server is configured with a simulated patient population size, resources per file, and optional error simulation.

Policies

Fair Use
The sandboxes are shared community test servers with synthetic data; keep traffic modest and never send real PHI or production load.
Async Polling Etiquette
Bulk Data $export clients should poll the Content-Location status URL with exponential backoff and honor Retry-After on 202 and 429 responses.
Data Resets
Sandbox data is synthetic and may be reset or reloaded at any time; do not depend on writes persisting.
