When to use this

Use it to turn a TikTok into text: repurpose a script, search what creators say, or feed it to an LLM. transcript is WEBVTT with timestamps (the same format other TikTok APIs return); text is the same words as plain text.

Transcripts come from TikTok's own captions: auto-generated speech captions (source: asr), the creator's own captions, or TikTok's translations. Most spoken videos have them. A video without captions (music only, or captions off) returns transcript: null with languages: [].

No captions? Pass use_ai_as_fallback=true and we transcribe the audio ourselves (source: ai) for videos up to 2 minutes. That costs 5 credits in total, and only when it runs; with captions it's still 1. If it hears no speech (music only), you get 404 transcript_unavailable for 1 credit, and that answer is cached.

By default you get the original language. Pass language (e.g. es) to pick one of languages.

Deleted, private and region-locked videos return 404 not_found.

Caching and freshness

Responses are cached for up to 30 days, so a repeat call within that window can return the same data. It still costs 1 credit.

Errors

Errors return { success: false, error, code, docs } with the HTTP status below. Validation errors, 401/402/429 rejections and 5xx failures are free; not_found is charged (how charging works). All error codes.

StatusCodeMeaning
401missing_api_keyNo API key. Send it in the x-api-key header.
401invalid_api_keyThe key is unknown or was revoked.
402insufficient_creditsNot enough credits for this call. Buy a pack or wait for tomorrow's top-up.
404not_foundThe endpoint, or the thing you asked for (ad, post, subreddit), doesn't exist. Charged when the platform was checked.
404transcript_unavailableThe video has no captions and speech-to-text heard no speech in it. Charged the base credit, never the speech-to-text extra; the answer is cached.
405method_not_allowedEndpoints take GET with query params.
429rate_limitedToo many calls at once. Wait for the retry-after seconds, then retry.
500internal_errorSomething broke on our side. Retry; 5xx errors are free.
502upstream_errorThe platform didn't give a usable answer. Retry; 5xx errors are free.
503upstream_busyAll our connections to the platform are busy. Retry in a few seconds; 5xx errors are free.

Use it in Claude

Once LurkAPI is connected to Claude, this endpoint is the tiktok_transcript tool. Ask in plain English, for example:

Ask Claude
Use LurkAPI's tiktok_transcript with url "https://www.tiktok.com/@hubspot/video/7671325437229845774" and summarize what you find.

Claude calls tiktok_transcript with arguments like these, and each call costs 1 credit; 5 if speech-to-text runs:
