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).

Pull the audio track out of a video.

Extract Audio

Extract the audio track from a video file and save it as MP3, WAV, or M4A.

API Endpoint

POST /api/v1/tools/extract-audio

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

Parameters

Parameter Type Required Default Description
format string No "mp3" Output audio format: mp3, wav, m4a

Example Request

curl -X POST http://localhost:1349/api/v1/tools/extract-audio \
  -H "Authorization: Bearer si_your-api-key" \
  -F "file=@clip.mp4" \
  -F 'settings={"format": "mp3"}'

Example Response

{
  "jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp3",
  "originalSize": 12500000,
  "processedSize": 3200000
}

Notes

  • If the video has no audio track, the request returns a 400 error.
  • MP3 is lossy but widely compatible. WAV is lossless but large. M4A (AAC) offers a good balance of quality and size.
  • When the source audio is already AAC and the output format is M4A, the audio stream is copied without re-encoding.
