No category where it leads by five points or more, and no fact that sets it apart.
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through a representative, the free sign-up link was dead on 14 October 2026, and rate limits, SLA and changelog are unpublished.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
- Send a fresh UUID in
HG-Idempotency-Keyon every POST and reuse it only when retrying the same payload - Poll async operations no sooner than the
Retry-Aftervalue and treat 454 as an expired result - Follow
link.relation=nextin Bundles rather than building offsets yourself - Expect mocked Patient360 data in sandbox unless network connectivity is enabled for the tenant
- Log
X-HG-Request-Idfrom each response for support cases
Particle Health
- Pass
projects/<project_id>as the scope when requesting a token, and request a new one every 60 minutes - Poll Get Query Status, or wait for the query-complete webhook, before reading FHIR or flat data
- Back off on 429, since limits change with system load
- Pass continuation tokens back verbatim when paging
- Use the published synthetic patients in sandbox, and stay under 500 queries a day
