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:

`bash

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

`bash

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

`bash

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)

`bash

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

`bash

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

`bash

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

`bash

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

`bash

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

`bash

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'
