Gemini Notebook API (NotebookLM API)

September 29, 2026 (October 20, 2026)

This is a third-party API for Gemini Notebook (formerly NotebookLM) by Google. It uses your Google AI subscription: Free, Plus $4.99, Pro $19.99, Ultra $99.99 or Ultra $199.99 a month (as of October 2026). This REST API and hosted MCP server turn web pages, PDFs and YouTube videos into podcasts (Audio Overviews), Video Overviews, slide decks, quizzes and cited answers, on a free Google account too. Google offers no Gemini Notebook API for regular Google accounts (as of October 2026).

MCP server

The hosted Gemini Notebook MCP server (NotebookLM MCP server) gives Claude Code, Cursor, VS Code and other AI assistants 57 tools for notebooks, sources, chat, Deep Research and every Studio output, with your useapi.net API token and nothing to install. The notebooklm-api repo also adds it in one step as a Claude Code plugin or a Gemini CLI extension, and has a Dify plugin with 56 tools for Dify workflows, chatflows and agents.

Pricing

How the useapi.net Gemini Notebook API (NotebookLM API) compares with Google’s own API (October 2026). Gemini Notebook has no credits and no price per item: podcasts, videos and every other result come out of your Google account’s usage, which refills every 5 hours up to a weekly limit, and a bigger Google AI plan gets more.

A free Google account makes everything except cinematic Video Overviews, which need Pro or Ultra (Plus doesn’t have them either), and each free account you connect adds its own usage.
Google publishes only notebook and source limits per plan: Free 100 notebooks and 50 sources each, Plus 200 and 100, Pro 500 and 300, Ultra 500 and up to 600 (Google’s limits). How much a single job uses depends on its length and type. GET /accounts/email shows each account’s live usage and when it refills.
Paid plans also let you share a notebook as chat only.

One Google account, four APIs

The same Google AI plan powers several useapi.net APIs, each from its own allowance, so one Google account connected to all of them gets the most out of the plan:

Google Flow API: Veo 3.1, Omni 1.2 Flash and Omni 1.1 Flash video, Nano Banana images up to 4K, from Flow credits.
Google Vids API: Omni 1.2 Flash video up to 15 seconds, 30-second talking avatar videos from a photo, avatars in 30 voices and text to speech, from the Vids allowance, which does not use Flow credits.
Gemini Notebook API (NotebookLM API): chat with sources, Deep Research and every Studio output, from the Gemini Notebook usage limits.
Flow Music API: full songs with Lyria in Google Flow Music, on the Flow Music plan your Google AI subscription includes (Starter on Plus, Plus on Pro, Member on Ultra) or on Flow Music’s own plans.

Each API is set up on its own setup page, and one useapi.net subscription covers all of them.

Start using the API

A single $15/month subscription covers every API on useapi.net — one token, all services. You connect up to 3 accounts per service, each with its own website subscription, and useapi.net handles the REST API, load balancing, and polling. Need more accounts? Each extra subscription is $10/month and adds 3 more accounts per service.

Subscribe — $15/month Pay with crypto

Pricing and volume options — full refund within the first 14 days if you have fewer than 50 successful generations. Already subscribed? Change the quantity in the Stripe Customer Portal instead of buying again.

Run several Gemini Notebook accounts

Each useapi.net subscription connects 3 Google accounts, up to 100 in total. Studio and research jobs don’t need email: each one goes to an account that is healthy, has a free job slot within its maxJobs and still has usage left for that job, so nobody has to watch Google’s 5-hour and weekly budgets. A one-shot request with urls or text creates the notebook on such an account for you. When every account is busy or out of usage you get 429, with retryAt when Google names the reset time, so wait or send the job to a specific account with email. GET /jobs shows the load on every account.

Every job can post its finished record to your webhook with replyUrl, or you poll GET /jobs/jobid, so a 10-minute Video Overview needs no open connection.

How useapi.net works has tips for keeping your accounts healthy.

Questions

Does Gemini Notebook (NotebookLM) have an API?

Through useapi.net, yes, for regular Google accounts: the Gemini Notebook API runs on your Google AI subscription, the free one included, with chat with citations, Deep Research and every Studio output. Google’s own Gemini Notebook Enterprise API needs Enterprise licenses in a Google Cloud project and covers only notebooks, sources, sharing and Audio Overviews (as of October 2026).

How much does the Gemini Notebook (NotebookLM) API cost?

Through useapi.net, a podcast, video or answer has no price of its own: it uses the Gemini Notebook usage of your Google AI subscription. It works on a free Google account, and a paid Google AI plan raises the usage. See the comparison.

Is there a Gemini Notebook (NotebookLM) API key?

Through useapi.net, you call Gemini Notebook with our API token, since Google issues no Gemini Notebook API key for regular accounts. You connect your Google account once through the automated browser setup: sign in with Google, with no cookies to copy and no Google Cloud project. We keep the session signed in, and if Google ever signs it out, you get an email with a one-minute re-add link.

Can I generate Gemini Notebook (NotebookLM) podcasts with the API?

Through useapi.net, yes: podcasts (Audio Overviews) and Video Overviews too. Send links or text to POST /artifacts and download the podcast as .m4a, a Video Overview as .mp4, slides as .pdf and .pptx or an infographic as .png. No code? The n8n tutorial turns web pages, YouTube videos or an RSS feed into a podcast.

Why use useapi.net instead of a free Gemini Notebook library?

Through useapi.net, Gemini Notebook runs hosted. The popular free libraries notebooklm-py and gemini-notebook-mcp-cli install and run on your own machine, while here nothing runs on your computer, so jobs keep going with your laptop off. We keep your Google session signed in with no cookies to refresh, report every job by webhook and spread jobs across up to 100 Google accounts. The Gemini Notebook API options article compares them side by side.
