Baidu Hot Search API
The live Baidu trending boards (百度热搜), read keyless from Baidu's public "top" board endpoint. Baidu is China's dominant search engine, and its hot-search board is the country's most-watched read on what people are searching for right now — the Chinese equivalent of Google Trends' real-time list, the pulse of the Chinese internet. The realtime endpoint returns the main national hot-search board ranked by heat: each entry with its rank, the trending word, Baidu's heat score (its own searches-driven ranking metric), whether it is rising, falling or steady, an editorial tag and a one-line description. The category endpoint returns one of Baidu's themed boards — film, TV drama, novels, games, cars or finance — the same way. This is the Baidu trending cut — distinct from the Western trends feeds (Google, Wikipedia, Reddit) and from the platform feeds in the catalogue: it is what China is searching for. Heat scores are Baidu's own ranking metric, not a raw search count; words and descriptions are in Chinese as Baidu publishes them. Counts are the real, live numbers Baidu shows; a short cache fronts the upstream. Keyless.

Reddit API
Real-time Reddit data as an API — subreddits, posts, comments, user profiles and search, returned as clean JSON. Pull a subreddit's info and its hot, new, top or rising posts; fetch a post together with its full comment tree; look up any user's profile, karma, submissions and comments; search posts across all of Reddit or within one subreddit; and list the trending posts and the most popular subreddits. Live data, paginated with Reddit cursors, with scores, upvote ratios, comment counts, flair, timestamps, thumbnails and media URLs. Ideal for social listening and brand monitoring, trend and sentiment dashboards, content aggregation, research and market intelligence, and bots. 11 data endpoints. Authenticated with an x-oanor-key; fair-use rate limits per plan.

Highlight API
Highlight search terms in text. The highlight endpoint wraps every match of one or more terms in a marker — defaulting to <mark>…</mark>, or any open/close strings you choose (** for Markdown, ANSI codes for the terminal, a CSS span, anything) — and returns the marked-up text and a match count. The snippets endpoint returns short excerpts of the surrounding context around each match, the way a search-results page shows where your query appears. Matching is case-insensitive by default with optional whole-word mode, and terms are matched literally (regex characters are safely escaped). Perfect for search results and in-page find, keyword spotting, log review and document previews. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. Distinct from search, summarization and diff APIs.

Stemmer API
Reduce words to their linguistic root (stem) with the classic Snowball stemming algorithms — running → run, fishing → fish, nationalization → nation — across 24 languages including English, German, French, Spanish, Italian, Portuguese, Dutch, Russian, Arabic, Finnish, Swedish and more. Stem a whole text (every word, returning both the per-word mapping and the fully stemmed text) or a single word. Stemming is the core normalisation step behind search engines, query expansion, text indexing, keyword matching and NLP preprocessing. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. Distinct from sentiment/NLP analysis and fuzzy string matching.
