The Agent is open source.
MIT-licensed and on GitHub: an MCP server your Claude or ChatGPT can call, and a TypeScript SDK for your app. It queries the free identity tier with a free key (30-second signup) and the verified paid tier when you upgrade.
Agent open, data paid
Open-sourcing the Agent lowers the bar to building on regulated-care data and keeps our method transparent. The defensible part isn’t the code — it’s the verified, source-linked facts behind it. So the Agent is free and open; the verified data tier is the product.
MCP server
Plug xcircl into Claude or ChatGPT — query providers in natural language.
TypeScript SDK
Typed function calls for your app. Works with a free key in 30 seconds.
Upgrade in place
