**APIs profiled:** 3

Unreal Speech is a low-cost, high-scale text-to-speech (TTS) API for turning text into natural-sounding speech. It exposes a small REST surface - a low-latency HTTP streaming endpoint, a synchronous speech endpoint that returns an MP3 plus per-word or per-sentence timestamps, and an asynchronous synthesis tasks endpoint for long-form audio up to 500,000 characters. Requests are authenticated with a Bearer API key issued from the dashboard, and pricing is metered per character with a free monthly allowance.
