# Introduction > Hybrid retrieval over licensed research and proprietary data, via REST API or MCP.

Licensed, non-public research and data: search it, or reach live tools.

## Start here Connect your client, or run your first search from code. Official Python, TypeScript and Go clients. API keys, scoping, and the Bearer token header. Build and test your integration without spending credits. The core endpoint: parameters, response shape, examples. Every public endpoint, with full parameter and response detail. ## Going further Four ways to search, and how to pick one. Tools beyond search (news mentions, aviation data, and more) through the same account. Agentic retrieval that plans its own searches and verifies every result. See what a search would return, and what it would cost, before you pay for it. Narrow results by metadata, dates, and identifiers. List what you can search, and what each collection supports. Every status code, what causes it, and how to fix it. What changed in the API, SDKs, CLI and docs, newest first.
