Frequently asked questions

What does the Video File Transcript API do?

The Video File Transcript API lets you extract the full, timestamped transcript from a public Utilities uploaded video or audio file using one POST request to /v1/video/transcript. It returns clean JSON — no OAuth or infrastructure setup required.

How many credits does the Video File Transcript API cost?

Billing is 1 credit per minute of audio (rounded up, minimum 1). Failed or empty results are never charged.

Do I need a Utilities API key or OAuth?

No. A single Captapi key works across every platform Captapi supports — YouTube, TikTok, Instagram, Facebook, Twitter/X, Reddit, Threads, Bluesky, Pinterest, LinkedIn, Rumble, Spotify, Kwai, and more. We handle proxies, rate limits, retries, and authentication for you.

Is the Video File Transcript API suitable for production use?

Yes. It is a stable REST endpoint with predictable JSON. Upload via multipart form field file (POST) — see the cURL sample. Use durationSeconds / creditsCharged to verify per-minute billing.
