Frequently asked questions
What does the Facebook Ad Transcript API do?
The Facebook Ad Transcript API lets you extract the full, timestamped transcript from a public Ad Library ad using one GET request to /v1/ad-library/facebook/ad-transcript. It returns clean JSON — no OAuth or infrastructure setup required.
How many credits does the Facebook Ad Transcript API cost?
Each successful call costs 17 credits. 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 Ad Library 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 Ad Library ad 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 Facebook Ad 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.
