Publish your first dataset

Create your account

Click Start selling at the top of the home page, fill in your email and a password, and click Create account, then confirm your email with the link we send you. Next comes Pick your handle: a short public name such as alex-weather, made of lowercase letters, numbers, and hyphens. It appears in the web address of every dataset you publish, and you can't change it later. Click Claim handle.

Your wallet, where agents' payments land, is created in the background. There's nothing to set up.

Upload your files

Put files that answer the same kind of question in one dataset: buyers pay one price to search the whole set. Click New dataset at the top right (a plus icon on a phone), then drop your files on the page or click Upload.

You can also drop a whole folder or a ZIP archive: quarry opens it in your browser and uploads the files inside. Files it can't use, such as system files or unsupported formats, are skipped, and the upload panel says which and why.

The dataset starts with a name taken from the folder or archive you drop, or from what your file names have in common. Once your files are ready, quarry suggests a better one (see step 5). Its web address follows the name until you publish; after that, the address stays.

PDF, Office, text, email, and image files work, up to 500 per dataset: see Prepare your files. Uploads keep going while you move around quarry, but keep the tab open while files show Uploading.

Wait until your files are ready

Each file is read and cut into passages: short excerpts that keep their file name, section, and page. A file shows Queued, then Preparing, then Ready. A few files are prepared at a time, and large files and scanned PDFs take a few minutes each. Once the upload is done, you can leave the page.

If a file shows Needs attention, its card says why, with a Retry or Remove button. More in Check what agents will receive.

Ask a test question

Open the Test tab and type a question your files should answer. You get the passages a paying agent would receive, in the same order.

No answer is written for the agent: it reads these passages and writes its own reply. If the right passages don't come back, find out why and fix it.

Check your listing

Once your files are ready, quarry reads them and drafts your listing: a name, a description, a category, and up to five example questions. Open Settings. Under Listing, the fields quarry filled in say Suggested from your files:

• Name: what a buyer would search for, such as "US semiconductor filings 2023 to 2025".
• Link: your dataset's web address. It follows the name until you publish, unless you type your own.
• Description: agents read it to decide whether to ask you, and search shows only its first 300 characters. It should start with what's inside and the years it covers.
• Category: pick a suggestion, such as finance or legal, or type your own.
• Example questions: shown on your public page and to agents, so they know what to ask. quarry checks each one against your files and shows how many a passage answers. After you change them, Check again; Try in Test shows the passages.

Change anything you like: what you write is never replaced. Draft again writes a new suggestion from your current files, for the fields that still hold quarry's text. Click Save changes.

Set a price

Under Pricing, keep Per question selected and enter your Price per question in USDC, a digital dollar worth one US dollar. The default is $0.01, which comes to $10 for 1,000 questions; 0 makes your dataset free. Click Save changes: one click saves the listing and the price together.

To choose a price, see Set your price.

Publish

The Publication card at the top of Settings lists what's left to do. When every line has a check mark, click Publish, then confirm. With changes you haven't saved, the button reads Save and publish and saves them first. A file that needs attention doesn't hold the others back: the confirmation says it's left out, and you publish with Publish without them. The confirmation also shows your dataset's web address, which stays the same from then on.

Your dataset is on the marketplace, and agents that search quarry can find it. A Your listing is live window opens with your listing's link and a Message you can edit, ready to post on X or LinkedIn or to send by email. Share on the Publication card opens it again.

Public page shows your listing as buyers see it: the name, your @handle, the description, the example questions, how many files and passages the dataset holds, the questions answered so far, and the price. It never lists or links your files.
