Installation

pip install notionary

Set your Notion integration token:

export NOTION_API_KEY=your_integration_key

---

Quick Start

All access goes through the Notionary client, which exposes namespace objects — each mapping to a Notion API area.

import asyncio
from notionary import Notionary

async def main():
    async with Notionary() as notion:
        # Find a page by title (fuzzy matching)
        page = await notion.pages.find("Meeting Notes")
        print(page.title, page.url)

        # Read content as Markdown
        md = await page.get_markdown()
        print(md)

        # Append content
        await page.append("## Action Items\n- [ ] Review proposal")

        # Replace all content
        await page.replace("# Fresh Start\nThis page was rewritten.")

asyncio.run(main())

Core API

Pages

async with Notionary() as notion:
    # Lookup
    page = await notion.pages.find("Sprint Board")
    page = await notion.pages.from_id(page_uuid)

    # List & search
    pages = await notion.pages.list(query="roadmap")

Content (Markdown API)

    md = await page.get_markdown()       # read as Markdown
    await page.append("## New Section") # append blocks
    await page.replace("# Replaced")   # overwrite all content
    await page.clear()                  # remove all blocks

Metadata

    await page.rename("New Title")
    await page.set_icon("🚀")
    await page.set_cover("https://example.com/cover.png")
    await page.random_cover()

Properties

    # Set a single property (type-validated against the schema)
    await page.set_property("Status", "Done")
    await page.set_property("Due Date", "2025-12-31")
    await page.set_property("Priority", 3)
    await page.set_property("Archived", True)
    await page.set_property("Tags", ["backend", "urgent"])

    # Set multiple properties in one API call
    await page.set_properties({
        "Status": "In Progress",
        "Due Date": "2025-12-31",
        "Priority": 2,
    })

    # Inspect the property schema (types, current values, valid options)
    schema = await page.describe_properties()
    # schema["Status"] → PagePropertyDescription(type="status", current="Todo", options=["Todo", "In Progress", "Done"])

Supported property types: checkbox, date, email, multi_select, number, phone_number, rich_text, select, status, title, url, relation.

For relation properties on data-source pages, you can pass a page ID (UUID string) or a page title — the title is automatically resolved to an ID:

    # By page ID
    await page.set_property("Project", "abc123...")
    # By title (auto-resolved via the related data source)
    await page.set_property("Project", "Quarterly Review")

Comments & Lifecycle

    await page.comment("Review completed")
    await page.lock()
    await page.trash()

Databases

async with Notionary() as notion:
    # Lookup
    db = await notion.databases.find("Tasks")
    db = await notion.databases.from_id(db_uuid)

    # Create
    db = await notion.databases.create(
        parent_page_id=page_uuid,
        title="New Database",
        icon_emoji="📊",
    )

    # Metadata
    await db.set_title("Project Tracker")
    await db.set_description("All current projects")
    await db.set_icon("📊")
    await db.lock()

Data Sources

Data sources represent queryable Notion databases with schema awareness — useful for building structured content pipelines.

async with Notionary() as notion:
    ds = await notion.data_sources.find("Engineering Backlog")

    # Schema introspection — property types, current options, and relation pages
    schema = await ds.describe_properties()
    # schema["Status"] → DataSourcePropertyDescription(type="status", options=["Todo", "In Progress", "Done"])
    # schema["Assignee"] → DataSourcePropertyDescription(type="relation", relation_options=[...])

    # Create a page inside the data source
    page = await ds.create_page(title="New Feature")

    # Query with filters
    results = await ds.query(filter={"property": "Status", "select": {"equals": "In Progress"}})

    # Metadata
    await ds.set_title("Sprint Board")
    await ds.set_icon("🧭")

File Uploads

from pathlib import Path

async with Notionary() as notion:
    # Upload from disk
    result = await notion.file_uploads.upload(Path("./report.pdf"))

    # Upload from bytes (e.g. generated images, in-memory content)
    result = await notion.file_uploads.upload_from_bytes(
        content=image_bytes,
        filename="chart.png",
    )

    # List previous uploads
    uploads = await notion.file_uploads.list()

---

Users

async with Notionary() as notion:
    all_users = await notion.users.list()
    people    = await notion.users.list(filter="person")
    bots      = await notion.users.list(filter="bot")
    me        = await notion.users.me()

    matches   = await notion.users.search("alex")

---

Workspace Search

async with Notionary() as notion:
    results = await notion.workspace.search(query="roadmap")
    for r in results:
        print(type(r).__name__, r.title)

---

Key Features

• No more hunting for opaque IDs or copying page URLs

Markdown Content API

• Read any Notion page as clean Markdown
• Append or replace blocks using Markdown syntax
• Powered by the official Notion Markdown API

Round-Trip Editing

# Read → transform → write back
md = await page.get_markdown()
updated = md.replace("Draft", "Final")
await page.replace(updated)

Modern Python

• Full async / await support throughout
• Type hints on all public APIs
• Pydantic models for all API responses
• Context-manager client for clean resource handling

AI-Ready Architecture

• Namespace-based API maps naturally to agent tool sets
• Predictable response models enable prompt chaining
• Works with LangChain, LlamaIndex, OpenAI Agents SDK, Claude, and custom agent runtimes
