SnapOtterandGitHub ecc0a45f0e docs: per-tool reference pages for all 157 tools (+ fix docs build) (#261)
* fix(docs): keep gray-matter on js-yaml 3 so the docs site builds

The js-yaml >=4.2.0 override from #257 forced js-yaml 4 onto gray-matter (used by vitepress and vitepress-plugin-llms), which calls the removed yaml.safeLoad and broke `vitepress build`. Scope a gray-matter>js-yaml ^3.14.1 override so gray-matter keeps the v3 API (build-time, trusted frontmatter only) while app code stays on js-yaml 4.2.0+.

* docs: add per-tool reference pages for all 157 tools, with a modality sidebar

Generate /tools/<id> pages for the 104 tools that lacked one (video 29, audio 17, document 36, data 10, and 12 newer image tools), matching the existing page format (API endpoint, parameters from the OpenAPI spec, curl example, response, notes). Async/AI tools document the 202+SSE flow and feature-bundle requirement.

Sidebar: add Video / Audio / PDF & Documents / Data groups with per-tool links, fold the 12 new image tools into the existing image categories, and replace the placeholder rest.md-anchor group. Docs site builds cleanly (157 pages, no dead links).

Convert speech to text with AI-powered transcription.

Transcribe Audio

Convert speech to text using AI-powered transcription (faster-whisper). Supports plain text, SRT, and VTT output formats with automatic or manual language selection.

API Endpoint

POST /api/v1/tools/transcribe-audio

Accepts multipart form data with an audio file and a JSON settings field.

Parameters

Parameter Type Required Default Description
language string No "auto" Language: auto, en, de, fr, es, zh, ja, ko, id, th, vi
outputFormat string No "txt" Output format: txt, srt, vtt

Example Request

curl -X POST http://localhost:1349/api/v1/tools/transcribe-audio \
  -H "Authorization: Bearer si_your-api-key" \
  -F "file=@audio.mp3" \
  -F 'settings={"language": "en", "outputFormat": "srt"}'

Example Response

This is an async tool. The API returns 202 Accepted immediately:

{
  "jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "async": true
}

Track progress via SSE at GET /api/v1/jobs/{jobId}/progress. When the job completes, the SSE stream delivers the final result with a downloadUrl.

Notes

  • Requires the transcription feature bundle to be installed. Returns 501 Not Implemented if the bundle is not available.
  • Uses faster-whisper for transcription. Language auto detects the spoken language automatically.
  • srt and vtt formats include timestamps for each segment, suitable for subtitles.
  • txt format returns plain text without timestamps.
  • This is a long-running AI tool; processing time depends on audio length and server hardware.
