You.com
US provider of search APIs that supply AI apps and agents with current web results, page content and multi-step research.
What it does
You.com provides web search as an API for AI applications. The Web Search API returns current results with filters for country, language, freshness and domains. The Contents API fetches the cleaned text of individual pages, and the Answer API generates answers with source citations. The Research API investigates in several steps and offers five depth levels from Lite to Frontier, plus a variant for financial topics. You connect via REST, a Python SDK or an MCP server; ready-made integrations exist for LangChain, LlamaIndex, n8n and Zapier, among others.
Who it suits
Development teams that want to feed chatbots, RAG applications or agents with up-to-date information from the web without running their own search index. Without programming skills you will get little out of it.
Data protection for businesses
The operator is SuSea, Inc. in San Francisco; hosting runs on AWS. The vendor does not mention EU data hosting. You.com bases transfers to the US on the EU-U.S. Data Privacy Framework, supplemented by standard contractual clauses. A data processing agreement (Data Processing Addendum) is available on the website. According to the privacy policy, prompts, files and outputs are not used to train the vendor’s own models, and the connected model providers are contractually barred from doing so. Zero data retention, SOC 2 attestation and custom rate limits come with the Enterprise plan.
Limits
Billing is per call; deep research costs many times more than simple searches. There is an official SDK only for Python. Even answers with sources can contain errors and should be checked.
