  description: >-
    **ALL CAPS AS A SERVICE** - the premier API for making text LOUDER.


    Send meek, lowercase text and receive it back with full volume. Includes
    SHOUT, SCREAM, and WHISPER endpoints, plus an experimental /v1/emphasize
    model that decides which words to emphasize for you.


    Authentication is via the `X-API-Key` header. For the demo, any non-empty
    key works except `acaas_banned_demo_key`, which has a revoked bullhorn.
