-H "Authorization: Bearer capt_live_..."What is the Linkbio API?
Extract public Linkbio page links and profile metadata. Every endpoint is a single authenticated GET request that responds with predictable JSON, so the data drops straight into dashboards, AI pipelines, RAG systems, and no-code automations.

Frequently asked questions
What is the Linkbio API?+
The Linkbio API is a REST API from Captapi that returns public Linkbio data as clean, structured JSON. It covers 1 endpoint — Page — behind one Bearer API key, with no OAuth flow and no scrapers to build or maintain.
What data can I get from the Linkbio API?+
Extract public Linkbio page links and profile metadata. Each endpoint is a single GET request that responds with predictable JSON fields, so the data is ready for dashboards, AI pipelines, and automations.
Do I need a Linkbio developer account or OAuth?+
No. You only need a Captapi key (capt_live_...), sent as an Authorization: Bearer header. The same key works across all 29 platforms Captapi supports. We handle proxies, rate limits, retries, and parsing for you.
How much does the Linkbio API cost?+
Linkbio endpoints cost between 4 and 4 credits per call, depending on the endpoint. New accounts start with 100 free credits (no credit card), and repeat calls are served from a 24-hour cache for 0 credits.
Can AI agents use the Linkbio API?+
Yes. Every Linkbio endpoint is exposed as a tool in the official MCP server (@captapi/mcp) for Claude, Cursor, and VS Code, and is also available through the @captapi/cli CLI, an n8n community node, a Make.com app, and an Apify Actor.
Is the Linkbio API suitable for production use?+
Yes. It is a stable REST API with predictable JSON, automatic retries, upstream fallbacks, and a shared 24-hour cache. Only successful responses consume credits — failed or empty results are never charged.
