notion

Use the Notion API to create/read/update pages, data sources (databases), and blocks.

Setup

1. Create an integration at https://notion.so/my-integrations
2. Copy the API key (starts with ntn_ or secret_)
3. Set the environment variable NOTION_API_KEY
4. Share target pages/databases with your integration (click "..." → "Connect to" → your integration name)

API Basics

All requests need:

curl -X GET "https://api.notion.com/v1/..." \
  -H "Authorization: Bearer $NOTION_API_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json"

Note: The Notion-Version header is required. This skill uses 2025-09-03 (latest). In this version, databases are called "data sources" in the API.

  -H "Content-Type: application/json" \
  -d '{"query": "page title"}'

Get page:
