# CMF Rulings Search

> Search the rulings (dictámenes) Chile's Comisión para el Mercado Financiero has issued since 2011 in answer to consultations. Free text in Spanish matches the CMF's summary of the question and the answer. Filter by `effects` (`particulares` or `generales`), `letter_number`, `year` and the issue date (`from_date`/`to_date`). Each result carries the letter itself. Served by Croma (`as_of` says how current the data is).

**Dataset endpoint**: answers from the whole source in milliseconds and carries `as_of`.

  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.
