Introduction

The Daylite API is a REST API at https://api.daylite.me/v1. It returns JSON and authenticates with a personal API key. Everything you can read here comes from the same account data that the Daylite desktop and web apps sync, so changes made in the apps appear immediately.

Read-only for now

This version can read data. Creating and updating tasks, and an MCP server for AI assistants, are next.

Quickstart

In Daylite, open Settings → Developer and create an API key. Copy it; it is shown only once.
Call the API with the key as a Bearer token:

curl https://api.daylite.me/v1/tasks?due_to=2026-11-09 \
  -H "Authorization: Bearer $DAYLITE_API_KEY"
