For Agents

Read and write Notion pages, databases, blocks, comments, and files; supports markdown reads, page moves, and database queries.

Quickstart

Get started with Notion API in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"create a Notion page"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

View OpenAPI Document

Jentic publishes the only available OpenAPI document for Notion API, keeping it validated and agent-ready.

Jentic publishes the only available OpenAPI specification for Notion API, keeping it validated and agent-ready. Notion is a workspace combining notes, databases, and project tracking inside a single block-based document model. The API exposes 42 endpoints covering pages, databases, blocks, users, comments, files, and views, including markdown-aware page reads and writes. It supports the operational tasks of programmatically reading workspace content, creating pages and databases, manipulating block trees, and integrating Notion with other systems.

Use Cases

Patterns agents use Notion API API for, with concrete tasks.

★ Notion as a Knowledge Source for AI

An AI assistant pulls Notion pages as markdown to ground its answers in the team's working documents. The /v1/pages/{page_id}/markdown endpoint returns ready-to-feed text without needing the agent to walk the block tree, which dramatically simplifies retrieval-augmented workflows over Notion content.

Fetch the markdown of the 'Engineering Runbook' page and use it as context to answer an on-call question

Database-Driven Project Tracking

An automation queries a Notion task database for items assigned to a user with a due date this week, creates a daily summary page, and links the open tasks. The /v1/databases/{database_id}/query endpoint applies filters and sorts server-side; /v1/pages creates the summary and /v1/blocks/{block_id}/children appends the task list.

Query a Notion task database for items due this week assigned to a user, then create a summary page listing those tasks with links

Two-Way Document Sync

A documentation pipeline writes Notion pages from a markdown source of truth and pulls back edits as markdown for review. The markdown read and write endpoints make round-tripping practical without translating block structures by hand, while comment endpoints surface reviewer feedback for triage.

Update a Notion page from a markdown file via PATCH /v1/pages/{page_id}/markdown, then read back any comments left by reviewers

AI Agent Notion Operator

An AI agent helping a knowledge worker creates pages, moves pages between parents, appends checklists, and queries databases on request. Through Jentic, the agent searches for the right Notion operation, loads the schema, and calls /v1/pages, /v1/blocks/{block_id}/children, or /v1/databases/{database_id}/query as the request requires.

Create a new Notion page titled 'Meeting Prep', append three checklist blocks for the agenda, and move the page under the Weekly Meetings parent

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Notion bearer integration secrets are stored encrypted in the Jentic vault. Agents receive scoped execution access — the raw integration secret never enters the agent's prompt or context.

Intent-based discovery

Agents search Jentic by intent (e.g. 'create a Notion page' or 'query a Notion database') and Jentic returns the matching operation with its input schema attached.

Time to first call

Direct Notion integration: 1-2 days for auth, block tree handling, and database filters. Through Jentic: under an hour — search, load schema, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Alternative

Coda API

Coda combines docs and tables in a similar all-in-one workspace model.

Choose Coda when the workspace already runs on Coda or when spreadsheet-style docs are central; choose Notion when the workspace is on Notion.

Alternative

Airtable API

Airtable focuses on structured databases with views, while Notion is doc-first with database support.

Choose Airtable when the data is primarily relational and structured; choose Notion when content is mixed prose and structured data.

Complementary

Atlassian Jira API

Pair Jira issue tracking with Notion documentation for engineering workflows.

Use Jira for tickets and sprints; use Notion for the longer-form runbooks and meeting notes that link to those tickets.

FAQs

Specific to using Notion API API through Jentic.

Why is there no official OpenAPI spec for Notion API?

Notion does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Notion API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Notion API use?

Notion uses HTTP bearer authentication with an integration secret. Through Jentic, the bearer token is stored in the vault and injected at execution time, so the agent never sees the raw integration secret.

Can I read a Notion page as markdown with this API?

Yes. GET /v1/pages/{page_id}/markdown returns the page rendered as markdown, which avoids walking the block tree manually. PATCH on the same path lets you update a page from a markdown source.

What are the rate limits for the Notion API?

Notion's public documentation notes an average of three requests per second per integration. The OpenAPI spec does not encode this — implement an exponential backoff on 429 responses and check the latest Notion developer docs for current limits.

How do I query a Notion database through Jentic?

Search Jentic for 'query a Notion database'. Jentic returns the database query operation with its filter and sort schema, so the agent submits a structured filter directly without browsing the Notion docs.

Can I move a Notion page to a different parent?

Yes. PUT /v1/pages/{page_id}/move accepts a new parent reference and reparents the page. This is useful for restructuring workspaces or archiving completed work.
