​
send whisper.
RECEIVE THUNDER.

A REST API for making text LOUDER. Send meek, lowercase strings and receive them back with full volume. Six endpoints. One mission. Zero chill.

​
Try it

curl https://api.acaas.example.com/v1/shout \
  -H "X-API-Key: demo" \
  -H "Content-Type: application/json" \
  -d '{"text": "hello world"}'
Response
{
  "original": "hello world",
  "result": "HELLO WORLD",
  "characters_amplified": 11
}

​
Endpoints at a glance

Shout

POST /v1/shout — uppercase a string. The essential endpoint.

Scream

POST /v1/scream — uppercase with configurable exclamation intensity (1–10).

Whisper

POST /v1/whisper — the quiet cousin. Returns lowercase.

Emphasize

POST /v1/emphasize — experimental. A model picks which words to bold.

Health

GET /v1/health — service health. No auth required.

Rate limits

GET /v1/rate-limits — check your quota without spending a request.

​
Why ACAAS

Fast. P99 latency under 12ms, because capital letters are cheap.
Loud. Configurable intensity — from polite emphasis to sustained yelling.
Secure. Your lowercase text never leaves our servers. We promise.

​
Quickstart

1

Get an API key

For the demo, any non-empty string works. In production, generate one from the dashboard.
2

Make your first request

POST to /v1/shout with your lowercase text in the body.
3

Handle the response

You get back original, result, and characters_amplified.

​
Authentication

Every request requires an X-API-Key header. For the demo, any non-empty key works — except acaas_banned_demo_key, whose bullhorn has been revoked.
Request size is capped at 10,000 characters. Larger payloads will be rejected with a polite, lowercase error.

​
FAQ

You could. But does .toUpperCase() come with a dashboard, rate limits, and a 99.99% uptime SLA? Didn’t think so.
The product is a joke. The docs are not.
A model trained to identify which words in a sentence most deserve emphasis. Non-deterministic and may change between versions. See /v1/emphasize.
