Tellius

Tellius is an agentic analytics platform that deploys AI agents ("Kaiya") on governed enterprise data to automate root cause analysis, variance decomposition and insight delivery across structured and unstructured sources. It sits above the data warehouse (Snowflake, Databricks, BigQuery, Redshift) without moving data, and exposes its analytics engine to developers three ways: a REST + WebSocket platform API (login/JWT, Search, Insights and ML prediction endpoints), an iFrame + postMessage embedding surface for Vizpads, Search, Kaiya and Feeds, and a hosted MCP server that any MCP client can call over streamable HTTP with OAuth. Because Tellius ships as a per-customer Kubernetes deployment, every API base URL and MCP endpoint is tenant-specific rather than a single shared public host. Founded by Ajay Khanna; SOC 2 Type II certified; 5x Gartner Magic Quadrant Visionary for Analytics and BI Platforms (2022-2026).

Tellius publishes 2 APIs on the APIs.io network. Tagged areas include Company, Analytics, Business Intelligence, Agentic Analytics, and Decision Intelligence.

The Tellius catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Tellius’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 24 more developer resources.
