Install Jentic One Beta

Connect the Books API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Books API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

For Agents

Search Google Books, retrieve volume metadata, and manage authenticated user bookshelves, reviews, and reading positions across 51 endpoints.

Use for: Search for books by a specific author, Find a volume on Google Books using its ISBN, Retrieve metadata for a Google Books volume by id, List all volumes on a user's favorites bookshelf

Not supported: Does not handle full-text book content delivery, ebook DRM, or audiobook streaming - use for catalog metadata search and user bookshelf management only.

Use Cases

Patterns agents use Books API for, with concrete tasks.

★ Reading App Catalog Search

Power a consumer reading app's search experience by querying the Google Books catalog for matches against a user's free-text query, returning titles, authors, cover thumbnails, and preview availability. The Books API exposes the same index that powers books.google.com, so apps avoid building and maintaining their own metadata corpus. Integration is typically a single GET against /books/v1/volumes with a query string.

Search /books/v1/volumes for q="isbn:9780547928227" and return the title, authors, and thumbnail URL of the top result.

Personal Library Management

Let users curate their Google Books bookshelves directly from a third-party reading app, supporting add, remove, list, and reorder operations on shelves like Favorites, Reading Now, and To Read. The API authenticates with OAuth 2.0 user credentials and respects existing privacy settings on each shelf. This eliminates the need to duplicate library state in a separate backend.

Add the volume id zyTCAlFPjgYC to the authenticated user's bookshelf 3 (Reading Now) using the mylibrary endpoint.

Citation and Bibliography Tools

Build a citation generator that resolves an ISBN or free-text reference to a fully populated bibliographic record including authors, publisher, publication date, page count, and ISBN-10/13 identifiers. Researchers and writers use this to auto-fill citation styles such as APA, MLA, or Chicago without manual entry. One volumes lookup yields enough data to format most major styles.

Look up volume metadata for ISBN 9780062316097 and format an APA-style citation from the returned title, authors, publisher, and year.

AI Agent Reading Assistant via Jentic

An AI agent uses Jentic to discover the Books API's search and library operations and acts as a reading concierge - finding next-read recommendations from a user's existing bookshelves, fetching previews, and updating reading position as the user finishes chapters. Jentic isolates the user's OAuth token in its vault so the agent never handles raw credentials. End-to-end integration takes under an hour through Jentic search-load-execute.

Through Jentic, search for the books_volumes_list operation, load its schema, and execute a query for q="subject:fantasy" maxResults=10.

Key Endpoints

Why Jentic?

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

Credential isolation

Your Google OAuth client credentials and user refresh token are stored once, encrypted, by your own Jentic One instance and injected at execution time. The agent receives only short-lived scoped access tokens and never sees the raw client secret in its prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'search Google Books by isbn' or 'add a volume to my bookshelf', and Jentic returns the matching volumes or bookshelves operation with its parameter schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Books API through Jentic.

What authentication does the Google Books API use?

The Books API uses OAuth 2.0 for authenticated user-library operations and accepts an API key for public catalog reads. When called through Jentic, the OAuth token or API key is stored encrypted in your Jentic One instance and the agent receives only scoped access - raw credentials never enter the agent context.

Can I search for a book by ISBN with the Books API?

Yes. Send a GET to /books/v1/volumes with the query parameter q=isbn:9780547928227 (substituting the target ISBN). The response includes the title, authors, publisher, page count, and preview availability of any matching volume.

What are the rate limits for the Google Books API?

Google enforces a default of 1,000 queries per day per project for the Books API, with per-user limits applied on authenticated calls. Higher quota can be requested via the Google Cloud console. Track usage in the API dashboard before scaling integrations.

How do I add a book to a user's bookshelf through Jentic?

Use the Jentic search query "add a book to a Google Books bookshelf" to discover the mylibrary.bookshelves.addVolume operation, load its schema, and execute it with the authenticated user's shelf id and the target volumeId. Run pip install jentic to get started.

Is the Google Books API free to use?

Yes, the Books API is free for the default daily quota. Some operations require an authenticated user (OAuth 2.0) but there is no per-call charge from Google for catalog or library access.

Can the Books API return full text or only previews?

The API returns metadata, snippets, and preview URLs but does not stream full book content. Where the publisher allows, the volume response includes a viewability field and a preview link to books.google.com for in-browser reading.

Can I limit what my agent is allowed to do with the Google Books API?

Yes. Because Jentic One is self-hosted, your own rules decide which Books API operations and credentials the agent may use, so you can grant it read-only catalog search on /books/v1/volumes while withholding any bookshelf write. The bookshelf operations carry the shelf in the URL path, such as /books/v1/mylibrary/bookshelves/{shelf}/addVolume, so a rule can pin the agent to a single shelf where it may add and remove volumes and nowhere else. Operations you do not enable, like removeVolume or changing user settings, stay out of reach until you add them.
