**Looking for endpoints?** Our [API reference](https://trmnl.com/api-docs) is generated from the same tests that run against our code, so it's always current -- every endpoint, parameter + response shape. Also available as [Markdown](https://trmnl.com/api-docs.md) (handy for LLMs) + raw [OpenAPI](https://trmnl.com/api-docs/openapi.json).
