TikTok Audience Demographics API

Audience country + language mix for a TikTok creator — engagement sample, not a follower census.

Give a profile URL, @handle, or username and get a ranked audience-country breakdown as clean JSON. TikTok does not publish follower geography — we sample people engaging with recent videos. The two signals come from two populations, disclosed in the response: audienceLanguages[] are tallied from top-level commenters (basis.language="commenters"), while audienceLocations[] come from repliers under the most-replied parent comments (basis.region="repliers") — the only public surface that reliably exposes user.region. Each country row carries country name, countryCode, count, and numeric percentage (+ percentageText). Response includes sampleSize, totalCountries, regionSampleParents + regionSampleVideos (how many distinct parent threads / videos the region sample is spread over), and a clustering-aware confidence: the size-based label (low <400, medium 400–999, high ≥1000) is CAPPED when the region sample is concentrated in few threads (<8 parents or <4 videos → low; <20 parents or <8 videos → at most medium), because 400 repliers from 6 threads are not 400 independent observations. Optional other{} only when countriesLimit truncates. timings{path,postsVia,postsMs,postsDeadlineMs,commentsMs,commentsVia,totalMs,videoConcurrency,commentsAttempts,commentsErrors,commentsAttemptsPerVideo} — postsVia names the leg that served the video list (native), commentsVia the comments surface (web+replies), commentsErrors counts blocked comment requests absorbed before clean pages, and commentsAttemptsPerVideo is the per-video attempts distribution (sorted desc). If the posts leg hits its deadline on a real profile you get a degraded 200 (degraded:true, degradedReason:"posts-timeout", 0 credits) — 404 NOT_FOUND is reserved for profiles positively confirmed absent, never for a slow fetch. Choose videos=12|30|60 (credits 3/5/8) for sample depth. Percentages across audienceLocations (+ other) sum to ~100%. This reflects who engages, not a full follower census.
