Endpoints at a glance

POST /v1/shout

Uppercase a string. The essential endpoint.

POST /v1/scream

Uppercase with configurable exclamation intensity (1 to 10).

POST /v1/whisper

The quiet cousin. Returns lowercase.

POST /v1/emphasize

Experimental. A model picks which words to bold.

GET /v1/health

Service health. No auth required.

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 ACAAS servers. 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 For the demo, any non-empty key works — except acaas_banned_demo_key, whose bullhorn has been revoked.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. ACAAS rejects larger payloads with a polite, lowercase error.

FAQ

Why not just use .toUpperCase()?

You could. But does .toUpperCase() come with a dashboard, rate limits, and a 99.99% uptime SLA? Didn’t think so.

Is this a joke?

The product is a joke. The docs are not.

What's the experimental emphasis model?

A model trained to identify which words in a sentence most deserve emphasis. Non-deterministic and may change between versions. See /v1/emphasize.
