  description: >-
    Government-data APIs for Colombia, Peru, Mexico, United States, Brazil, El
    Salvador, Bolivia, and Japan, 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-*`):
    https://docs.usecroma.com/rate-limits.

      description: >-
        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.

        both policies, e.g. `"webSearch";q=100;w=3600, "default";q=100;w=86400`.
