Frequently asked questions

What does the Linkbio Page API do?

The Linkbio Page API lets you fetch profile or page details and audience stats from a public Linkbio profile or page using one GET request to /v1/linkbio/page. It returns clean JSON — no OAuth or infrastructure setup required.

How many credits does the Linkbio Page API cost?

Each successful call costs 1 credit. 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.

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 Linkbio Page API suitable for production use?
