# ReTHUS Health Professional

> Check whether a person is registered in Colombia's national register of health professionals (ReTHUS) by document number: their titles and professions, the administrative act authorizing each, the reporting entity, and any social service or sanctions on record. `document_type` defaults to `CC`. Returns `found: false` when the document is not in the register.

  description: >-
    Government-data APIs for Colombia, Peru, Mexico, United States, Brazil, El
    Salvador, Bolivia, Japan, and Chile, plus global web search. Croma
    normalizes public-sector data into structured JSON for product teams and AI
    agents.


    Every operation is a POST with a JSON body and an organization API key as a
    bearer token; every operation is an idempotent lookup and accepts an
    optional `Idempotency-Key` header. Paths carry their major version (`/v1`);
    the versioning and deprecation policy, including the `Deprecation` and
    `Sunset` headers a retiring endpoint sends, is at
    https://docs.usecroma.com/versioning. Rate limits are per organization and
    reported on every response (`RateLimit-Policy`, `X-RateLimit-*`):

        Optional client-chosen key for this request (any string up to 255
        characters, e.g. a UUID). Every Croma operation is an idempotent lookup:
        repeating a request with the same body returns the same result and
        creates nothing, so retrying after a timeout or network failure is
        always safe. The key is echoed back in the `Idempotency-Key` response
        header so you can correlate a retry with its first attempt. Each attempt
        that reaches the API counts against the rate limit.
