  title: Aider CLI Chat Web API
  version: 0.86.1
  description: Documentation surface for the Aider command-line interface. Aider has no hosted REST API and does not bind to a network port — it runs entirely in a developer's terminal against the local Git working tree. This OpenAPI document models the Aider command surface as if it were a REST API so it can be consumed by API-centric tooling (catalogs, registries, governance rule engines, capability runtimes). Each slash command (`/add`, `/diff`, `/commit`, etc.) is modeled as a path; each launch-flag family is modeled as a configuration path. Servers and security blocks are placeholders — aider's actual security model is "use the user's local shell credentials and the LLM provider API key in the environment."
