Tekst hvilken som helst video
med tre API-kall

const API = 'https://autostud.ai/api/v1'
const KEY = process.env.AUTOSTUD_API_KEY

const call = async (path, body) => {
  const response = await fetch(API + path, {
    method: body ? 'POST' : 'GET',
    headers: {
      Authorization: `Bearer ${KEY}`,
      'Content-Type': 'application/json',
    },
    body: body ? JSON.stringify(body) : undefined,
  })

  const payload = await response.json()
  if (!response.ok) throw new Error(payload.error?.message || response.statusText)
  return payload
}

// 1. A video project to hang the timeline on.
const created = await call('/actions/videos.create', {
  video_name: 'Interview clip',
  video_type_id: 'timeline',
  video_format: 'portrait',
  video_lang: 'en',
})
const video_id = created.data.video_id

// 2. Transcribe, emphasise, style — one call.
const subtitled = await call('/actions/subtitles.generate', {
  video_id,
  media_url: 'https://cdn.example.com/interview.mp4',
  style_preset: 'beast',
  words_per_group: 3,
})
console.log(subtitled.data.word_count, 'words', subtitled.data.duration_seconds, 's')

// 3. Render it.
await call('/actions/renders.create', {
  video_id,
  video_type_id: 'timeline',
  video_format: 'portrait',
})

// 4. Wait for the worker. A webhook is better; this is the short version.
let render
do {
  await new Promise((resolve) => setTimeout(resolve, 15000))
  const list = await call(`/renders?video_id=${video_id}&limit=1`)
  render = list.data[0]
} while (render && ['not_started', 'processing'].includes(render.render_status))

if (render.render_status !== 'done') throw new Error('Render failed')
console.log(render.render_url)

Basis-URL: https://autostud.ai/api/v1 — autentiser med `Authorization: Bearer sk_live_…`. En `sk_test_`-nøkkel går nøyaktig samme vei og stopper før noe brukes.

1. 1

   Lag en API-nøkkel

   Dashbord, Innstillinger, API-nøkler. Ta forhåndsvalget "Automation" hvis du ikke vil velge scopes for hånd: det dekker videoer, rendringer og filer. Hemmeligheten vises én gang. `sk_live_` bruker, `sk_test_` validerer hele kallet og stopper før skrivingen.

2. 2

   Legg videoen bak en URL

   Det finnes ingen opplastings-endepunkt: API-et leser en URL. Din bucket, din CDN, en signert lenke — alt serverne våre kan hente. Å registrere den i arbeidsområdets bibliotek er valgfritt og endrer ingenting.

   # The API takes a URL, never a file upload. Anything publicly
   # reachable works: your bucket, your CDN, a signed URL.
   export MEDIA_URL="https://cdn.example.com/interview.mp4"
   
   # Optional: keep a record of it in the workspace library.
   curl -X POST https://autostud.ai/api/v1/assets \
     -H "Authorization: Bearer $AUTOSTUD_API_KEY" \
     -H "Content-Type: application/json" \
     -d '{
       "provider_file_url": "'"$MEDIA_URL"'",
       "provider_file_name": "interview.mp4",
       "file_mime_type": "video/mp4",
       "provider_file_id": "interview-2026-08-18",
       "sync_method": "api"
     }'

3. 3

   Opprett videoprosjektet

   `videos.create` returnerer `video_id`-en alt annet henger på. Send en `Idempotency-Key`, så gir et gjentatt kall det første svaret i stedet for å lage et prosjekt til.

     }'

4. 4

   Tekst den

   `subtitles.generate` gjør hele jobben på serveren: Whisper transkriberer med ordnøyaktig timing, en KI-gjennomgang markerer ordene som skal fremheves, og en av 116 stiler legges på. Svaret inneholder antall ord, nøyaktig lengde og oppdaget språk.

     }'

5. 5

   Køa rendringen

   `renders.create` legger jobben på workerflåten og svarer umiddelbart med `render_id`. En rendring koster 20 credits, uansett lengde.

     }'

6. 6

   Hent mp4-en

   Abonner på `render.completed`, så sendes den ferdige URL-en signert til deg. Vil du heller hente selv: list videoens rendringer og les `render_status` til den sier `done`.
