You.com is an enterprise and developer AI infrastructure platform built around real-time web search data. It provides a suite of core APIs — a low-latency search API, a contents API for retrieving pages across multiple URLs, a research API for complex investigative tasks, and a finance research API — letting AI agents and applications draw on accurate, real-time information. Launched in 2021 as a consumer AI search engine, the company has since shifted its focus to enterprise AI search infrastructure and its deep research agent “ARI” in response to the market changes that followed ChatGPT’s arrival.
Key Features
- Real-time Web Search API: A low-latency search API that returns LLM-ready snippets and metadata. It serves as an AI agent’s “eyes on the web” for retrieval-augmented generation (RAG) and fact-checking against current information
- Contents API (batch page retrieval): Extracts body text, summaries, and metadata from multiple URLs in batch requests — well suited for drilling into search results or building data-collection pipelines
- Research API (tiered investigation): Lets you choose the depth of investigation across multiple tiers — Lite / Standard / Deep / Exhaustive / Frontier — and returns source-backed answers. Complex research tasks that a single search cannot answer can be run via the API
- Finance Research API: A finance-focused research API covering corporate filings, macroeconomic data, and market research, offered in Deep / Exhaustive tiers designed for financial workflows
- “ARI” research agent: An enterprise deep research agent that analyzes hundreds of sources at once and generates cited reports in a short time. Beyond web data, it can integrate internal documents and premium databases
- Developer-friendly delivery: In addition to REST APIs, SDKs, a CLI, and an OpenAPI spec, an MCP server is available, so you can use it directly from AI coding environments such as Claude, Cursor, and VS Code

Pros & Cons
✅ Pros
- A full lineup of data-retrieval APIs for AI agents, from search and content retrieval to research and finance-focused research
- Pay-as-you-go with no minimum commitment; the free tier and free credit let you start small before committing
- The Research API’s tier selection lets you balance investigation depth against cost
- MCP server support means minimal setup when using it from AI tools such as Claude and Cursor
- Designed to return cited answers and reports, which makes verification easier in business use
⚠️ Cons
- Having pivoted from consumer AI search chat to an enterprise and developer focus, it is no longer a good fit for individuals who want to “use it as a search engine”
- Because API integration is assumed, the barrier is high for non-engineers using it on its own
- Higher-end APIs such as the Finance Research API have high per-call prices, so costs can add up without a focused use case
- Information and documentation in Japanese are scarce; the official docs are primarily in English
