2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Interact with the Notion API for creating and managing pages, databases, and blocks. Use when automating Notion workflows via REST API calls.

The file declares its own license as Sustainable Use License 1.0. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

notion

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

Setup

Create an integration at https://notion.so/my-integrations
Copy the API key (starts with ntn_ or secret_)
Store it:

mkdir -p ~/.config/notion
echo "ntn_your_key_here" > ~/.config/notion/api_key

Share target pages/databases with your integration (click "..." → "Connect to" → your integration name)

API Basics

All requests need:

NOTION_KEY=$(cat ~/.config/notion/api_key)
curl -X GET "https://api.notion.com/v1/..." \
  -H "Authorization: Bearer $NOTION_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.

Common Operations

Search for pages and data sources:

curl -X POST "https://api.notion.com/v1/search" \
  -H "Authorization: Bearer $NOTION_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json" \
  -d '{"query": "page title"}'

Get page:

curl "https://api.notion.com/v1/pages/{page_id}" \
  -H "Authorization: Bearer $NOTION_KEY" \
  -H "Notion-Version: 2025-09-03"

Get page content (blocks):

curl "https://api.notion.com/v1/blocks/{page_id}/children" \
  -H "Authorization: Bearer $NOTION_KEY" \
  -H "Notion-Version: 2025-09-03"

Create page in a data source:

curl -X POST "https://api.notion.com/v1/pages" \
  -H "Authorization: Bearer $NOTION_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json" \
  -d '{
    "parent": {"database_id": "xxx"},
    "properties": {
      "Name": {"title": [{"text": {"content": "New Item"}}]},
      "Status": {"select": {"name": "Todo"}}
    }
  }'

Query a data source (database):

curl -X POST "https://api.notion.com/v1/data_sources/{data_source_id}/query" \
  -H "Authorization: Bearer $NOTION_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json" \
  -d '{
    "filter": {"property": "Status", "select": {"equals": "Active"}},
    "sorts": [{"property": "Date", "direction": "descending"}]
  }'

Create a data source (database):

curl -X POST "https://api.notion.com/v1/data_sources" \
  -H "Authorization: Bearer $NOTION_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json" \
  -d '{
    "parent": {"page_id": "xxx"},
    "title": [{"text": {"content": "My Database"}}],
    "properties": {
      "Name": {"title": {}},
      "Status": {"select": {"options": [{"name": "Todo"}, {"name": "Done"}]}},
      "Date": {"date": {}}
    }
  }'

Update page properties:

curl -X PATCH "https://api.notion.com/v1/pages/{page_id}" \
  -H "Authorization: Bearer $NOTION_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json" \
  -d '{"properties": {"Status": {"select": {"name": "Done"}}}}'

Add blocks to page:

curl -X PATCH "https://api.notion.com/v1/blocks/{page_id}/children" \
  -H "Authorization: Bearer $NOTION_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json" \
  -d '{
    "children": [
      {"object": "block", "type": "paragraph", "paragraph": {"rich_text": [{"text": {"content": "Hello"}}]}}
    ]
  }'

Property Types

Common property formats for database items:

Title: {"title": [{"text": {"content": "..."}}]}
Rich text: {"rich_text": [{"text": {"content": "..."}}]}
Select: {"select": {"name": "Option"}}
Multi-select: {"multi_select": [{"name": "A"}, {"name": "B"}]}
Date: {"date": {"start": "2024-01-15", "end": "2024-01-16"}}
Checkbox: {"checkbox": true}
Number: {"number": 42}
URL: {"url": "https://..."}
Email: {"email": "[email protected]"}
Relation: {"relation": [{"id": "page_id"}]}

Key Differences in 2025-09-03

Databases → Data Sources: Use /data_sources/ endpoints for queries and retrieval
Two IDs: Each database now has both a database_id and a data_source_id
- Use database_id when creating pages (parent: {"database_id": "..."})
- Use data_source_id when querying (POST /v1/data_sources/{id}/query)
Search results: Databases return as "object": "data_source" with their data_source_id
Parent in responses: Pages show parent.data_source_id alongside parent.database_id
Finding the data_source_id: Search for the database, or call GET /v1/data_sources/{data_source_id}

Notes

Page/database IDs are UUIDs (with or without dashes)
The API cannot set database view filters — that's UI-only
Rate limit: ~3 requests/second average
Use is_inline: true when creating data sources to embed them in pages
