# Reference

This section lists every Kiln configuration key, environment variable, HTTP endpoint, and command-line flag. Definitions stay brief and precise; for background and step-by-step instructions, use the guides.

- **Configuration reference** — Every key, type, default, and constraint, section by section.
- **Environment variables** — Every variable and how it ranks against the config file.
- **API** — Endpoints, credentials, and response conventions.
- **CLI** — Startup flags, service subcommands, and health checks.
