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 post using one GET request to /v1/linkedin/post-transcript. It returns clean JSON — no OAuth or infrastructure setup required.

How many credits does the LinkedIn Post Transcript API cost?

Each successful call costs 1 credit. Pass cache=true to serve from the 24h shared cache (0 credits on hit); default is always fresh. 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, Rumble, Spotify, Kwai, and more. We handle proxies, rate limits, retries, and authentication for you.

What if the LinkedIn post 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 and automatic retries. Pass cache=true to serve from the 24h shared cache (0 credits on hit); default is always fresh. Use it for analytics, monitoring, and content automation.
