title: Captapi Linkme API
version: 0.1.0
summary: Structured public data from social platforms through one REST API.
description: 'Captapi returns public data (profiles, posts, comments, transcripts, search, ads, commerce) from social platforms as JSON.
Auth: send your key as `Authorization: Bearer capt_live_...` or `X-API-Key: capt_live_...`. Keys are created by a human at https://captapi.com/dashboard/api-keys.
Billing: each operation states its cost in `x-credit-cost`. The `X-Captapi-Credits` response header shows what was charged. Failed requests (4xx/5xx) are not billed. `cache=true` serves from the 24h cache, free on a hit where `billedOnCacheHit` is false. Where the price depends on which path served the call, `x-credit-cost.note` gives the full rule and the range we have observed.
Empty results: on many list and search endpoints a call that ran but found nothing is charged 0 credits (for example an ad-library or profile search with no matches). Where an empty result is still billed, the endpoint description says so; Google Maps business search, for instance, bills its one page because the lookup ran. The `X-Captapi-Credits` header always shows the actual charge.
Errors: every non-2xx response uses the same envelope, `{ success: false, error: { code, message, retryable } }`. Retry only when `retryable` is true, honouring `Retry-After`.
Timing: every response carries `Server-Timing: total;dur=`, the total time the request took. Deprecated: the `timings` object some endpoints still return in `data` will be removed from response bodies on 2026-12-17; use the header instead. It is not part of the response schemas below.
Response schemas are inferred from real captured responses and list the fields seen there plus documented top-level fields. Fields can be null when a platform does not expose them.

summary: Linkme Profile API
description: 'Linkme profile → bio, profileVisitCount, featured links, webLinks, email/infoLinks, stripeStatus.
Paste a Linkme URL (link.me/danucd) and get the public profile from Linkme''s dehydrated SSR payload (TanStack $tsr) — not HTML meta tags or the site footer. Identity: id, username, displayName, firstName/lastName when distinct, bio, avatar + isDefaultProfilePicture. Audience: profileVisitCount (e.g. 15.9k) and totalLinks (Linkme''s SSR counter — not links[].length). Flags: verifiedAccount, isAmbassador, isPrivate. Timestamps: createdAt/updatedAt. links[] are featured CTA rows; webLinks[] are social icon groups; infoLinks[] carry email/contact — three separate buckets, not a union. stripeStatus{tipsEnabled,stripeEnabled} signals monetization; socials{} + other[] cover mapped/unmapped networks. Flat 1 credit. Pass cache=true or cacheMaxAge (1d/3d/7d/14d/30d) for the shared response cache.
