Accounts and sandboxes are provisioned by Zus on request, with no public prices, no named security certification and no SDK.\n\n## Before you call either\n\n### Health Gorilla\n\n1. Send a fresh UUID in `HG-Idempotency-Key` on every POST and reuse it only when retrying the same payload\n2. Poll async operations no sooner than the `Retry-After` value and treat 454 as an expired result\n3. Follow `link.relation=next` in Bundles rather than building offsets yourself\n4. Expect mocked Patient360 data in sandbox unless network connectivity is enabled for the tenant\n5. Log `X-HG-Request-Id` from each response for support cases\n\n### Zus Health\n\n1. Cache the access token for its hour. More than 200 token requests an hour per App Client returns 429\n2. Request Patient History at most once per patient per 24 hours, and poll the job status endpoint\n3. Use conditional create by identifier so a retried write doesn't duplicate a resource\n4. Send `Zus-If-Match` with the resource's ETag on PUT and PATCH\n5. Set `_count` up to 500 on searches, since the default page is 10\n\n## Questions\n\n### Which is better for AI agents, Health Gorilla or Zus Health?\n\nHealth Gorilla scores 59.3 (C) on agent readiness against Zus Health's 56.6 (C), and leads in 4 of 7 scored categories.
