Verdicts

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.

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

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

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
