To query any open data just append
_public=true parameter to any FHIR endpoint. Like any other request against our platform, you must have a valid access_token to query our public data. Here's an example of how you could find a list of all the public doctors (FHIR provider) on 1upHealth.
curl -XGET 'https://api.1up.health/fhir/dstu2/Practitioner?_public=true' \ -H 'Authorization: Bearer access_token'
Medications, Practitioners, and Organization resources are pre-populated using open data. These all have public permissions and will be returned when using any valid auth token.
In addition to fully populated FHIR resources, when data is imported into 1upHealth we appropriately link it to codes like LOINC, ICD, and DRGs.
