Transcribe video/audio URL to text + word-level timestamps using Bilibili Bcut ASR API (free, no API key). Preferred for Chinese content — Bcut gives character-level timestamps vs Whisper word-level. Returns text + segments [{start, end, text}]. Requires yt-dlp + ffmpeg.
Transcribe video/audio URL or local file to text + SRT using yt-dlp + Groq Whisper API (free tier). Preferred default for v2 transcription. Returns raw text and segments; summary is caller's responsibility.
Transcribe video/audio URL or local file to text + SRT using yt-dlp + OpenAI Whisper API. Paid fallback for v2 transcription when Groq is rate-limited or unavailable. Returns raw text and segments; summary is caller's responsibility.
Transcribe video/audio URL or local file to text + SRT using yt-dlp + local mlx-whisper (Apple Silicon). Free, offline, fastest on M-series Macs. Opt-in advanced path for users with Apple Silicon + mlx-whisper installed. Returns raw text and segments; summary is caller's responsibility.
Deep URL fetch using crawl4ai (Playwright-powered) for JS-rendered pages, anti-bot sites, and dynamic content. Slower than fetch-jina but handles sites that block simple fetchers. Requires user-installed crawl4ai package.

OpenAlex provides broad scholarly metadata coverage across papers, preprints, chapters, and other research outputs through a free public API. It is useful when the query needs paper titles, authors, abstracts, citation counts, and open-access landing pages across a much larger corpus than a single publisher or preprint server.
api_search - Calls https://api.openalex.org/works with the search query parameter and per-page=10, then maps results entries into normalized evidence.api_search - Reconstructs abstract text from OpenAlex's positional abstract_inverted_index representation before building snippet and content fields.api_search - Resolves evidence URLs in priority order: best_oa_location.landing_page_url, then doi, then the OpenAlex id fallback.search query parameter for keyword search, not filter, which is for metadata filtering syntax.
