# Tenure developer docs

Tenure puts an AI retention flow in front of the cancel button and gives support agents a Recommend/Enable API. These pages are the developer documentation, served as Markdown; the machine-readable API reference is the OpenAPI document.

Agents: [llms.txt](https://app.trytenure.co/llms.txt) lists these pages; [llms-full.txt](https://app.trytenure.co/llms-full.txt) is all of them in one file; the API reference is [openapi.json](https://app.trytenure.co/api/openapi.json).
