## Which one, for what

### Health Gorilla (C)

Good for: US providers, labs and digital health companies that need network record retrieval and lab ordering through one FHIR API with a QHIN behind it.

Ahead on:
- Reliability, 58 against 45
- Schema & documentation, 80 against 65
- Security & auth, 66 against 41
- Transparency & trust, 61 against 56

Watch for: No public prices. Fees are set case by case and the sandbox is requested by form

### Metriport Medical API (D)

Good for: US care providers and digital health companies that need a patient's network records as FHIR with webhooks.

Ahead on:
- Maintenance & community, 74 against 63

Also in its favour:
- Open source

Watch for: Every API key has full access, including destructive operations, with no scopes

## 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
