Linkbio Page API

What is the Linkbio Page API?

Paste an lnk.bio URL and get the public page as clean JSON. Identity: id (lnk.bio numeric string, e.g. "-1344625"), handle/username, url, avatar. displayName/name are emitted only when lnk.bio publishes a real display name — @handle OG titles are not synthesised (null/omitted). socials{} is derived from data-network icon rows and username CTAs (facebook/twitter/instagram/tiktok/youtube/snapchat/triller/website/whatsapp/…) other[] holds typed social networks we could not map to a known key so nothing disappears. Top-level website / email / whatsapp when published. links[] includes content buttons (pb-linkbox) plus primary social icons with titles from icon labels (Facebook, Instagram, Triller, …) — not null. lnk.bio does not expose follower counts or a verified badge. Flat 1 credit. Pass cache=true or cacheMaxAge (1d/3d/7d/14d/30d).

What you get

• lnk.bio id + avatar + handle (no fabricated displayName)
• socials{} filled from icon rows
• links[] with titles on social rows + content buttons
• website / email / whatsapp + other[] for unmapped networks

Fill in the parameters below and copy a ready-to-run request, or open the live Playground to run it against your account (no API key paste).

  -H "Authorization: Bearer capt_live_..."
