Getting started
API v1RESTWebSocket

Overview

QuickVoice is two endpoints: one that turns text into speech, one that turns speech into text. Both stream, both take the same bearer key, and both bill per character to four decimal places.

Preview The request and response shapes are confirmed; some fields and limits may change before general availability.

Base URL

Every request goes to a single host. There are no regional subdomains to pick between.

base url 
https://api.quickdial.ai

Authentication

Authenticate with a bearer token in the Authorization header. The same key works for text-to-speech, speech-to-text and both WebSocket stream endpoints. You do not need separate credentials per service.

header 
Authorization: Bearer qtts_live_xxxxxxxxxxxxxxxxxxxx

Create and rotate keys from the dashboard. Keys are secret, so treat them like a password and keep them server-side. A browser that calls the API directly will leak the key to anyone who opens devtools; proxy through your own backend instead.

Your first request

This returns an Opus audio stream and writes it to a file:

curl 
curl https://api.quickdial.ai/v1/tts \
  -H "Authorization: Bearer $QUICKVOICE_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text":"I found three options that match your request.","voice":"azelma"}' \
  --output speech.opus

How billing works

  • Text-to-speech: $0.0028 per 1,000 characters of input text (Opus). WAV output is $0.0045 per 1,000 characters, reflecting the larger lossless payload.
  • Speech-to-text: $0.0018 per 1,000 characters of transcribed output.
  • Usage is metered to four decimal places and shown per request in the dashboard, so an invoice reconciles to the cent.
  • New accounts get 100,000 characters free, roughly 100 minutes of speech. No card required, and no monthly minimum after that.

Concurrency and uptime

Workers are stateless and designed to scale horizontally. Request rate is governed per key and reported in response headers, so separate workloads can be isolated cleanly. See Errors & limits for the headers that report the current request budget.
