Narakeet Video API

openapi: 3.0.3
info:
  title: Narakeet Account Video API
  description: The Narakeet API turns text and Markdown scripts into narrated audio and video programmatically. It exposes a text-to-speech endpoint (returning MP3, M4A, or WAV) in two modes - a short-content streaming mode that returns audio bytes directly, and a long-content JSON polling mode that returns a status URL to poll while a longer build runs asynchronously - plus a Markdown-to-video build workflow (upload a zip of the script and assets, trigger a build, then poll for the finished MP4), a voice listing endpoint, and an account credits endpoint. All build requests authenticate with an `x-api-key` header. API access requires a top-up or metered commercial Narakeet account; free and unmetered accounts cannot use the API. The default quota is 86,400 requests per day (1 per second). Pre-signed status and result URLs returned by the polling and video workflows do not require the API key.

      summary: Poll a build status URL
      description: Represents polling the pre-signed `statusUrl` returned by the polling audio build and the video build. The actual URL is time-limited and pre-signed, so no API key is required. Poll until `finished` is true, then read the `result` download URL. This path is illustrative; always use the exact statusUrl returned in the build response.
