## 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:
- Schema & documentation, 80 against 74
- Agent ergonomics, 72 against 49
- Security & auth, 66 against 32
- Transparency & trust, 61 against 55

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

### ROOK (C)

Good for: A wellness, insurance, corporate wellness or remote monitoring product that wants normalised wearable data pushed to its backend, with plan prices it can see up front.

Ahead on:
- Reliability, 75 against 58
- Payments & pricing, 25 against 5
- Maintenance & community, 73 against 63

Watch for: Credentials are one client UUID and secret per environment, sent by Basic auth, with no scopes or rotation documented

## 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.

**ROOK.** Graded on the REST API. A public OpenAPI file, a free Sandbox from the self-serve portal, published plan prices and a dated changelog. Credentials are one client UUID and secret per environment with no scopes, 429 handling isn't documented, the API is meant for occasional queries rather than bulk reads, and no SOC 2 report or security contact was found.

## 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

### ROOK

1. Send HTTP Basic auth with client_uuid as the username and the secret key as the password, plus a User-Agent header, or the WAF returns 403
2. Use https://api.rook-connect.review for Sandbox and https://api.rook-connect.com for production. Each has its own credentials
3. Read health data from the data webhook. Use the API only for occasional queries, and stay under 60 requests a minute
4. Deduplicate summaries on document_version and datetime. ROOK resends a summary with a higher document_version when it changes
5. Call POST /api/v1/user_id/{user_id}/data_sources/revoke_auth to end a connection. Some providers take hours to stop sending data
