## 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 69
- Agent ergonomics, 72 against 53
- Security & auth, 66 against 57
- Maintenance & community, 63 against 27
- Transparency & trust, 61 against 48

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

### Particle Health (D)

Good for: US providers, payers and digital health companies that need a patient's network records as FHIR or flat data, and care-event alerts.

Watch for: Credentials come from a Particle representative, and the 'play for free' sign-up domain did not resolve

## 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.

**Particle Health.** Particle queries Carequality, CommonWell, eHealth Exchange and state HIEs for a patient and returns FHIR R4B, flat data or C-CDA, with project-scoped 60-minute tokens and OpenAPI fragments per endpoint. Credentials come through a representative, the free sign-up link was dead on 14 October 2026, and rate limits, SLA and changelog are unpublished.

## 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

### Particle Health

1. Pass `projects/<project_id>` as the scope when requesting a token, and request a new one every 60 minutes
2. Poll Get Query Status, or wait for the query-complete webhook, before reading FHIR or flat data
3. Back off on 429, since limits change with system load
4. Pass continuation tokens back verbatim when paging
5. Use the published synthetic patients in sandbox, and stay under 500 queries a day
