Retrieve available plain-text transcripts for public YouTube video URLs with the actual language, available languages, caption source, channel context, and duration.

- Video summarization: Use available transcript text to create summaries, research notes, or content briefs for long videos.
- Searchable video archives: Index transcript text with video IDs, titles, channel information, and language metadata.
- Topic and information extraction: Identify topics, entities, claims, and keywords across a selected collection of public videos.
- Translation and localization: Use the selected and available language fields to route transcript text into translation workflows.
- The endpoint returns at most one plain-text transcript record per public video URL.
languageis a preferred BCP-47 language, not a guarantee; always use the result'slanguagefield as the actual language.- Videos without an available public transcript do not produce a result, so result count can be lower than input count.
- Transcript text does not include guaranteed segment timestamps or speaker labels.
All requests use the shared asynchronous flow:
submit -> task_id -> poll task -> read every cursor page -> save results
cp .env.example .env
export SOCQ_API_KEY="your-api-key"Run the complete Node.js workflow:
cd node
npm startRun the complete Python workflow:
python3 -m pip install -r python/requirements.txt
python3 python/main.pyBoth examples load payload.example.json, retry transient API responses, wait
for task completion, read every cursor page, and save a searchable plain-text transcript collection with actual-language metadata to
output/results.json.
Never expose SOCQ_API_KEY in browser code, mobile apps, public repositories,
screenshots, fixtures, or logs.

}The submit response contains data.task_id. Poll the task endpoint until
data.status becomes succeeded or failed, then continue with
data.results.next_cursor while data.results.has_more is true.
The Node.js and Python programs implement the production-shaped happy path:
- Load and validate configuration.
- Submit the endpoint-specific payload.
- Retry rate-pressure and transient server responses with bounded backoff.
- Poll the asynchronous task with a ten-minute application timeout.
- Stop cleanly on a failed task and surface the public error message.
- Read all cursor pages instead of silently returning only the first page.
- Write a stable JSON artifact containing task metadata and normalized records.
Use the synthetic files in fixtures/ for tests and documentation. They do
not contain customer, account, or production data.
See docs/production-notes.md for validation,
retry, timeout, pagination, deduplication, logging, and endpoint-specific
guidance.
- Use only publicly accessible YouTube channels, videos, Shorts, comments, transcripts, and fields supported by the selected endpoint.
- Do not use the examples to access private videos, restricted content, unavailable transcripts, or authentication controls.
- SocQ is not an official API of the represented social platform and is not affiliated with or endorsed by that platform.
- Before production use, assess the laws, platform terms, privacy obligations, and retention requirements that apply to your organization and use case.
- Collect only the fields needed for a defined purpose, restrict access, set retention periods, and support correction or deletion workflows where required.
- Platform names and trademarks belong to their respective owners.
