Frequently asked questions

What does the LinkedIn Post Transcript API do?

The LinkedIn Post Transcript API lets you extract the full, timestamped transcript from a public LinkedIn video using one GET request to /v1/linkedin/post-transcript. It returns clean JSON — no OAuth or scraping setup required.

How many credits does the LinkedIn Post Transcript API cost?

Each successful call costs 7 credits. Responses are cached for 24 hours, and cached results cost 0 credits. Failed or empty results are never charged.

Do I need a LinkedIn 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, and Rumble. We handle proxies, rate limits, retries, and authentication for you.

What if the LinkedIn video has no captions?

When no captions are available, Captapi transcribes the audio with AI (Whisper) automatically, so you still get a usable transcript.

Is the LinkedIn Post Transcript API suitable for production use?

Yes. It is a stable REST endpoint with predictable JSON, automatic retries, and a shared 24-hour cache. Use it for RAG pipelines, analytics, monitoring, and content automation.
