Ingest public TikTok videos to capture transcripts, captions, and rich context (author, hashtags, audio, etc.). Horizon handles downloading and transcription without any extra infrastructure.

​
Request body

  • sourceUrl — TikTok share link or canonical URL. Required if file is not provided.
  • file — Optional uploaded video file (multipart/form-data).
  • sourceName — Optional label saved with the transcript.
  • options — Optional object. Supported keys:
    • transcriptionModel — Preferred transcription backend (whisper-large-v3, etc.).
    • segmentLength — Target characters per chunk (default 600).
    • includeCaptions — Boolean; merge official captions when present (default true).
  • webhookUrl — Optional HTTPS URL Horizon should call when the extraction finishes.

​
Sample request

curl https://api.horizon.new/v1/extract/tiktok \
  -H "Content-Type: application/json" \
  -d '{
    "sourceUrl": "https://www.tiktok.com/@horizon/video/739201234567890",
    "sourceName": "Horizon Walkthrough",
    "options": {
      "transcriptionModel": "whisper-large-v3",
      "segmentLength": 550,
      "includeCaptions": true
    }
  }'

# or upload the TikTok video directly

curl https://api.horizon.new/v1/extract/tiktok \
  -H "Content-Type: application/json" \
  -d '{
    "file": "data:video/mp4;base64,AAAAHGZ0eXBpc29... ",
    "sourceName": "Horizon Walkthrough",
    "options": {
      "transcriptionModel": "whisper-large-v3",
      "segmentLength": 550,
      "includeCaptions": true
    }
  }'

​
Response

Returns 202 Accepted with jobId, status, statusUrl, and optional etaSeconds. Completed jobs include transcript chunks, TikTok details (author handle, publish time, hashtags), and audio track info.

​
Notes

  • Only public videos are supported; private or subscribers-only content cannot be fetched.
  • If TikTok throttles access, the job automatically retries with backoff before failing.
  • Provide campaign labels in your datastore to keep downstream analytics organized.
  • Poll GET /jobs/{jobId} (equivalent to statusUrl) to check progress or retrieve the final transcript and accompanying details later.
  • To upload a downloaded TikTok video, send multipart/form-data with a file field instead of sourceUrl.

x402 flow

TikTok extraction is priced via Coinbase’s x402 protocol. When a payment proof is missing, Horizon sends: 
HTTP/1.1 402 Payment Required
Content-Type: application/json

{
  "x402Version": 1,
  "accepts": [
    {
      "scheme": "exact",
      "network": "base-sepolia",
      "maxAmountRequired": "220000",
      "resource": "POST /extract/tiktok",
      "description": "Horizon TikTok extraction",
      "mimeType": "application/json",
      "payTo": "0xYourReceivingWallet",
      "maxTimeoutSeconds": 600,
      "asset": "0xYourUSDCContract",
      "extra": {
        "name": "USDC",
        "version": "1"
      }
    }
  ],
  "error": null
}
Pass the accepts payload to your facilitator, execute /verify and /settle, then replay the extraction request with the Base64 token in X-PAYMENT. Horizon finalizes the job and returns settlement details in X-PAYMENT-RESPONSE.
