--- title: "Marketplace" description: "Use when you want to find books by other authors, subscribe to one, understand Professional-only books, or publish your own." url: https://docs.heytrove.ai/concepts/marketplace updated: 2026-10-06 --- # Marketplace > Load this page when: you are browsing, subscribing to or publishing marketplace books ## For agents - Browse with `trove marketplace browse --search ""`. It needs no sign-in. - Never run `trove marketplace subscribe` without the user's approval. - Publishing needs the Professional plan. The marketplace is a catalog of books by other authors. Subscribing to a listing adds the book to your [library](https://docs.heytrove.ai/concepts/library-and-books.md), so your agent can read it like any other book. ## Ask your agent | Task | What to tell your agent | | --- | --- | | Browse | "Show me the Trove marketplace." | | Search by topic | "Find Trove marketplace books about testing." | | Sort | "Show the newest books in the Trove marketplace." | | Filter by tag | "Show Trove marketplace books tagged security." | | Subscribe | "Subscribe to the testing book you found." | | Unsubscribe | "Unsubscribe from the testing book in my Trove library." | You can also browse in the web app at [Marketplace](https://heytrove.ai/marketplace). ## Browse Browsing needs no account. You can ask for fewer results, for example "Show the top five." Each listing has a listing id, which your agent uses to subscribe. ## Subscribe and unsubscribe After your agent subscribes, the book appears in your library. Unsubscribing removes it from your library. If an author delists a book, you keep read access while you stay subscribed. ## Professional books Some listings are labelled Professional. On the Personal plan, your agent sees a preview of the first pages. Upgrade at [billing](https://heytrove.ai/billing) to read the whole book. ## Publish your own Publishing a book needs the Professional plan. Write the book as Markdown, then publish it from the web app. See [Plans and limits](https://docs.heytrove.ai/reference/plans-and-limits.md) for what each plan includes. ## Why agents ask before subscribing The [librarian](https://docs.heytrove.ai/subagents/librarian.md) recommends marketplace books but never subscribes on its own. To start the librarian, ask your agent explicitly: "Search my Trove library for how we handle retries." It shows an offer box when a marketplace book fits, and your agent subscribes only after you say yes. This keeps your library and your plan limits under your control. ## Best practice Pick marketplace books that match your work, and subscribe only to the ones you choose. See [Set up your library](https://docs.heytrove.ai/usage/set-up-your-library.md). Your own documents are worth more than famous books, so see [What goes in the library](https://docs.heytrove.ai/best-practices/what-goes-in-the-library.md). Publishing has no fixed rules, only guidance. Write the book privately first. Remove personal data and company secrets. Remember that every change to a public book is public. See [Run Trove for a team](https://docs.heytrove.ai/best-practices/run-trove-for-a-team.md). ## Direct CLI Your agent runs these through the `trove` command. You can run them yourself in a terminal, but asking your agent is the recommended way: it picks the right flags, waits for processing and checks the result. | Task | Command | | --- | --- | | Browse | `trove marketplace browse` (`--limit ` caps the results) | | Search by topic | `trove marketplace browse --search ""` | | Sort | `trove marketplace browse --sort newest` (or `popular`, `az`) | | Filter by tag | `trove marketplace browse --tag ` | | Subscribe | `trove marketplace subscribe ` | | Unsubscribe | `trove marketplace unsubscribe ` | See the [CLI reference](https://docs.heytrove.ai/reference/cli.md) for every flag. ## Related - [Library and books](https://docs.heytrove.ai/concepts/library-and-books.md) covers reading what you subscribed to. - [Librarian](https://docs.heytrove.ai/subagents/librarian.md) explains how books get recommended.
