Your next customer is an agent.
List the reports, research, and data your business already has. AI agents use what they need and pay your price for each question.
A creator uploads market-study.md and opens the processed source. The report carries the Google Docs icon; the opening also shows a PowerPoint deck and a Word document, with their Microsoft icons, as examples of the formats quarry accepts. Only the report is uploaded. The camera moves into the real report: small businesses grew fastest, at 18% quarter over quarter in Q3. The creator types a price of 0.01 USDC per question and publishes. In a chat, a user asks an agent which customer segment grew fastest in Q3; quarry asks the agent for payment, a USDC token travels from the agent to quarry, the payment of 0.01 USDC is confirmed, the seller's running total ticks from 0.00 to 0.01 USDC, and only then the agent answers with the sourced excerpt and cites its source. ChatGPT, Claude and Gemini are named as examples of agents that can call quarry; the recorded buyer was a script. The Analytics card, labeled Sample data, then shows illustrative figures: a revenue chart that draws itself, totals and a history of paid questions from example agents. They illustrate the dashboard and are not the recorded sale, which was one paid query for 0.01 test USDC. The film returns to the original file. The report and the published badge are pixels from the real product recording; the drag, the typing, the chat and the payment steps are recreated from the verified receipt. The report is fictional; the x402 transaction on Base Sepolia is real. Processing waits are edited out.

Sell the answer. Your report stays private.
A market study sells to the few clients who can afford all of it. On quarry, an agent buys only the answer it needs, at the price you set. It never gets the report.

Common questions.
Something we didn't cover? Email us.
Do I need any technical skills?
No. You upload, check what quarry prepared, set a price, and publish. The technical part is ours.
Can I get paid in dollars, to my bank?
Yes, with a monthly plan: buyers pay by card through Stripe, and Stripe pays out to your bank account. You can also charge per question, which settles in USDC, a digital dollar worth one US dollar, into a wallet quarry sets up for you. Withdraw it to any crypto wallet or exchange whenever you like. You can offer either option, or both.
What does quarry cost?
Nothing to list. On sales per question, quarry takes no cut today: the agent's payment goes to your wallet, not through ours. On monthly plans, Stripe's card fees apply, and any quarry commission is shown before you connect Stripe. If that ever changes, you will hear it from us before it applies to you.
How much of my document does a buyer see?
Only the passages that answer the question asked: five by default, twenty at most, each with the file and page it came from. Buyers never receive the file itself. Before paying, agents searching quarry can see a short preview, up to 200 characters, of your best-matching passage; you can turn previews off at any time. Rebuilding a whole report would mean paying for every question it takes, and you can read those questions in your dashboard.
What happens to the files I upload?
They stay private in your account until you publish. quarry does not train models on your files, and you can take a listing down whenever you like.
Do I need the rights to what I upload?
Yes. List only what you own or are allowed to sell, such as your own reports, research, and data. You keep ownership of everything you upload.
How do agents find my listing?
Your listing appears in the quarry marketplace and in a directory that agents query directly. After its first sale it is also listed in Coinbase's index of services that accept agent payments. You don't have to promote anything.
Why would an agent pay instead of searching the web?
Because what's in your files isn't on the open web. A search engine can't reach it, so an agent that needs it comes to your listing and pays your price.
Is anyone actually buying?
Agent payments are new, and we won't pretend otherwise. The standard behind them, x402, was created by Coinbase in 2025 and is now run by an open foundation under the Linux Foundation, with Cloudflare, AWS, Stripe, Visa, and Mastercard among its members. Coinbase alone has processed more than 100 million x402 payments. Listing is free, so the cost of being early is the hour it takes to upload.
What records do I get for my accounting?
Every paid question is logged in your dashboard with its date and amount, and each USDC payment links to its public receipt. Monthly plans come with Stripe's invoices and payout reports.
What kinds of files can I use?
PDF, Word, Excel, PowerPoint, OpenDocument, CSV, TSV, JSON, JSON Lines, Markdown, HTML, EPUB, email, images, and plain text: documents up to 50 MB, images 20 MB, text and data 10 MB.
Your first sale is one file away.
