Notion API

Use the Notion API via curl to create, read, update pages, databases (data sources), and blocks. No extra tools needed — just curl and a Notion API key.

Prerequisites

1. Create an integration at https://notion.so/my-integrations
2. Copy the API key (starts with ntn_ or secret_)
3. Store it in ~/.hermes/.env:

   NOTION_API_KEY=ntn_your_key_here
   

4. Important: Share target pages/databases with your integration in Notion (click "..." → "Connect to" → your integration name)

API Basics

All requests use this pattern:

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

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

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

Get Page

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

Get Page Content (blocks)

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

Create Page in a Database

curl -s -X POST "https://api.notion.com/v1/pages" \
  -H "Authorization: Bearer $NOTION_API_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 Database

curl -s -X POST "https://api.notion.com/v1/data_sources/{data_source_id}/query" \
  -H "Authorization: Bearer $NOTION_API_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 Database

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

Add Content to a Page

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

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": "2026-01-15", "end": "2026-01-16"}}
• Checkbox: {"checkbox": true}
• Number: {"number": 42}
• URL: {"url": "https://..."}
• Email: {"email": "user@example.com"}
• Relation: {"relation": [{"id": "page_id"}]}

Key Differences in API Version 2025-09-03

• Databases → Data Sources: Use /data_sources/ endpoints for queries and retrieval
• Two IDs: Each database 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

Notes

• Page/database IDs are UUIDs (with or without dashes)
• Rate limit: ~3 requests/second average
• The API cannot set database view filters — that's UI-only
• Use is_inline: true when creating data sources to embed them in pages
• Add -s flag to curl to suppress progress bars (cleaner output for Hermes)
• Pipe output through jq for readable JSON: ... | jq '.results[0].properties'
