Frequently asked questions

What does the Reddit Post Transcript API do?

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

How many credits does the Reddit Post Transcript API cost?

Each successful call costs 2 credits. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Hits include cached + cachedAt. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Failed or empty results are never charged.

Do I need a Reddit 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 Reddit Post Transcript API suitable for production use?
