# Terac > Terac is the expert labor MCP: the supply layer for verified human labor in a world where AIs run companies. We aggregate and vet domain experts, then expose them programmatically so any agent, product, or research tool can source the exact human it needs on demand and pay out only on verified completion. Terac started in market research (panel plus AI-moderated interviews for UXR and product teams) and is expanding into human data for frontier model training (RL post-training with domain experts) and labor infrastructure for AI-run companies. The platform is built on four pillars: Panel (supply aggregation, health, and targeting), Moderator (an AI voice agent that screens, interviews, and verifies experts), Recruiter (sources niche audiences via ads, referrals, and outbound), and the API/MCP (the programmatic interface where agents define a job and Terac gets it done). ## Core Platform - [Home](https://terac.com): Overview of Terac's expert labor platform and the four product pillars - [About](https://terac.com/about): Terac's mission to build the supply layer for verified human labor - [AI Research](https://terac.com/ai): AI-moderated interviews and how agents source verified experts on demand - [Enterprise](https://terac.com/enterprise): Enterprise-grade solutions for large organizations - [Market Research](https://terac.com/market-research): Panel and AI-moderated interviews for UXR and product teams - [User Research](https://terac.com/user-research): Recruit and interview users for product and UX studies ## For Experts and Researchers - [Panel](https://terac.com/panel): How Terac aggregates, vets, and verifies its expert panel - [Researchers](https://terac.com/researchers): Define studies, filters, screeners, and review submissions - [Recruiters](https://terac.com/recruiters): Source niche audiences via targeted recruitment and referrals - [Opportunities](https://terac.com/opportunities): Open research opportunities experts can apply to - [Leaderboard](https://terac.com/leaderboard): Top-performing experts on the platform - [Referral Program](https://terac.com/referral): Refer experts and earn rewards ## Developers and Agents - [Developer Docs](https://terac.com/docs/developers): API and MCP reference for sourcing verified human labor programmatically - [Expert Docs](https://terac.com/docs/experts): Guides for experts using the platform - [Developer llms.txt](https://terac.com/docs/developers/llms.txt): LLM-friendly index of the developer documentation - [Developer llms-full.txt](https://terac.com/docs/developers/llms-full.txt): Full text of the developer documentation for LLMs ## Resources - [Blog](https://terac.com/blog): Insights on AI research, expert labor, and human data for model training - [Customers](https://terac.com/customers): Case studies and customer success stories - [Stories](https://terac.com/stories): Longer-form customer stories - [What's New](https://terac.com/whats-new): Product updates and changelog - [Help Center](https://terac.com/help): Documentation and guides for using the platform - [FAQ](https://terac.com/resources/faq): Frequently asked questions ## Company - [Careers](https://terac.com/careers): Open positions and life at Terac - [Team](https://terac.com/team): The people building Terac - [Press](https://terac.com/press): Press kit and media resources - [Brand](https://terac.com/brand): Brand assets and guidelines - [Events](https://terac.com/events): Upcoming and past events - [Contact](https://terac.com/contact): Get in touch with the Terac team ## Optional - [Privacy Policy](https://terac.com/legal/privacy-policy): How Terac handles user data - [Terms of Service](https://terac.com/legal/terms-of-service): Legal terms for using the platform - [Cookie Policy](https://terac.com/legal/cookie-policy): Information about cookie usage - [Support Terms](https://terac.com/legal/support-terms): Terms and conditions for customer support
