Used to power AI systems, AI Agents, research tools, data pipelines, and more, You.com's Research API is a single API call that researches a question and returns a complete, cited answer. Leveraging AI, the API reads multiple sources, cross-references what it finds, and synthesizes everything into a structured response with inline citations.<br>Most applications that need web-grounded answers today require building a pipeline: search for results, fetch and parse pages, feed content to an LLM, handle citations. The Research API replaces that pipeline. You send a question, set a research effort level, and get back a Markdown-formatted answer with numbered citations tied to sources, ready to render or feed downstream. There is no additional parsing, ranking, or synthesis required on your end.
The Research API runs an autonomous reasoning loop that scales with the complexity of the question. It plans its own search strategy, breaks the question into sub-questions, and manages context across hundreds or thousands of reasoning steps. At the highest effort levels, a single query can run more than 1,000 reasoning turns and process up to 10 million tokens, well beyond what any single LLM context window can hold.
Configurable Research Depth
The `research_effort` parameter controls how much compute the API allocates to a query. Higher effort means more searches, deeper source reading, and more cross-referencing at the cost of longer response times. Four tiers are available: `lite`, `standard`, `deep`, and `exhaustive`. Pricing is fixed per tier.
Use Cases
- Research automation: Replace manual research workflows with an API call that returns a cited, synthesized answer.
- Question answering: Power internal or customer-facing Q&A with grounded, multi-source responses.
- Due diligence and compliance: Synthesize regulatory, financial, or competitive intelligence into citation-backed briefs.
- Content generation: Generate cited drafts grounded in real-time sources across any domain.

AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
You pay per 1,000 Research API calls, with no upfront commitment. The four options are effort tiers that set how much compute each call uses. Lite handles quick factual lookups and costs the least per 1,000 calls. Standard is the default, balancing depth for most production use. Deep supports complex multi-source research and synthesis. Exhaustive analyzes across dozens of sources. Prices rise as effort increases, since higher tiers run more searches and deeper reasoning. You choose the tier per request, so cost scales with the depth each question needs.
Top-of-mind questions for buyers
What counts as one Research API call for billing?
One call is a single research request you submit to the API. Each request runs a multi-step pipeline that searches the web, reads pages, and synthesizes a cited answer. You are billed per 1,000 calls at the effort tier you set on that request, regardless of how many internal searches it runs.
How does cost change if I set a higher effort tier on a request?
You set the effort tier per request, and the per-1,000-call rate for that tier applies. Higher tiers allocate more compute for more searches and deeper reasoning, so they cost more per 1,000 calls. A single Exhaustive query can run over 1,000 reasoning turns and process up to 10 million tokens.
Are there feature differences between the effort tiers beyond depth?
Structured JSON output is available with Standard, Deep, and Exhaustive, but not with Lite. Sending an output schema with Lite returns an error. All tiers return cited, source-backed answers with inline references and support domain, recency, and country source controls.

API
Prerequisites
You need a You.com API key. Get one at you.com/platform.
Getting Started
You.com works wherever your agents run. Pick the integration that matches how you're already building.
Claude Code, Cursor, VS Code, Windsurf, or any MCP client -> MCP Server -> Zero-config, no API key required to start
Claude Agent SDK or Claude.ai -> Skills -> Drop-in web search for Claude
LangChain, LangGraph, LlamaIndex, Vercel AI SDK -> Framework integrations -> Native tools and retrievers, no wrapper code
n8n, Zapier -> Automation platforms -> No-code web search across 8,000+ apps
Every integration wraps the same three APIs: Search (live web and news results), Contents (full page extraction), and Research (multi-step synthesis). One API key works across all of them.
Quick example (Python)
import os
from youdotcom import You
you = You(api_key_auth=os.environ["YDC_API_KEY"])
response = you.research(input="What are the latest breakthroughs in quantum computing?")
print(response.output.content) # markdown with inline citations
print(response.output.sources) # list of sources used
