Verdicts

Health Gorilla

A TEFCA QHIN with a FHIR R4 API, OpenAPI fragments on every reference page, idempotency keys on POST and dated weekly release notes. Access is sales-led, with case-by-case fees, a sandbox by request and no published rate limit numbers, and the API terms allow access to be cut at any time.

Metriport Medical API

One network query pulls a patient's records from HIEs, pharmacies and labs and returns deduplicated FHIR, with per-operation rate limits, RFC 7807 errors and AGPLv3 source. Each API key has full access with no scopes, there are no public prices, and the sandbox opens only after Metriport approves the account.

Before you call either

Health Gorilla

  1. Send a fresh UUID in HG-Idempotency-Key on every POST and reuse it only when retrying the same payload
  2. Poll async operations no sooner than the Retry-After value and treat 454 as an expired result
  3. Follow link.relation=next in Bundles rather than building offsets yourself
  4. Expect mocked Patient360 data in sandbox unless network connectivity is enabled for the tenant
  5. Log X-HG-Request-Id from each response for support cases

Metriport Medical API

  1. Check the errors array after Start Network Query. It returns 2XX even when some sources fail
  2. Wait for network-query.* webhooks or poll Get Network Query Status before reading consolidated data, which is cached from the last query
  3. Send the resource's eTag in If-Match on updates to avoid overwriting newer data
  4. Keep patient creates under 15 a minute and network queries under 20 a minute per source
  5. In sandbox, create patients whose first name matches a pre-defined persona to get example records
