You.com: You.com 提供適用於 LLM 應用程式的即時網頁搜尋 API,但包含更廣泛的對話推論功能。 Yep.com 每月有 155,834 次造訪,月增率 +6.2%,定價模式為免費。You.com 每月有 948,349 次造訪,成長率 +7%,定價模式為免費增值。

以 Ahrefs 索引打造的獨立網頁搜尋與 Agent 檢索 API
提交查詢即可取得來自獨立索引的排序頁面而非僅連結,避免依賴單一商業搜尋供應商。
每條結果都包含可回答查詢的段落,讓語言模型無須解析整頁即可讀取相關上下文。
單一 API 呼叫即可為模型回傳開放網路上下文,專為 RAG 與 Agent grounding 流程設計。
自 2010 年以來爬取約 1,000 億頁面,每 24 小時更新約 80 億頁面,結果保持相對新鮮。

為 AI 模型提供即時網路資料的搜尋與推論 API
p50 約 0.4 秒回傳排序後的網頁與新聞結果,支援 highlights、knowledge、正文擷取與網域過濾,適合生產級 RAG 負載。
提交既有 URL,即可依頁回傳乾淨的 Markdown 或 HTML,依回傳頁數計費而非依請求計費。
Answer 一次呼叫回傳帶引用的答案;Research 會規劃、閱讀整頁並交叉比對來源,提供五個深度層級。
一個相容 OpenAI 的 chat completions API,可執行領先的開源權重模型,並支援多供應商自動故障轉移。
專項更強Firecrawl crawls and converts websites into clean LLM markdown, but is primarily a scraper rather than a live search index.
專項更強Powerful enterprise neural search and discovery platform, but focuses more on internal site search than live web retrieval.
專項更強Pinecone is a managed vector database and AI knowledge platform for building retrieval-augmented generation (RAG), semantic search, and agent memory. It stores vector embeddings at scale, makes writes searchable within seconds with no index tuning, and keeps p99 latency steady as data grows. Pinecone powers products for more than 10,000 customers and over a million developers worldwide.
