USDCUSDC to your wallet

Each payment goes from the buyer wallet to your merchant wallet.

Sell what you already make.

Six ways to put a price on your work. Each one uses the same hosted checkout.

  • Product

    A one-time price for a digital product or service.

    Price: one-time

  • Subscription

    Access for a set period. The buyer approves each renewal payment.

    Renewal: buyer approves

  • Download

    Attach a file. The paid buyer gets a temporary link to it.

    Delivery: temporary link

  • Invoice

    Send one customer a payment link for a set amount.

    Sent to: one customer

  • Paid API

    Put a price on an API call. Your response follows the payment.

    Price: per call

  • Agent-paid checkout

    An AI agent with its own wallet pays the same checkout as a person.

    Payer: agent wallet

The money path, in three steps.

LinkSell hosts the checkout page. The USDC never passes through LinkSell.

  1. 01

    Create the price

    Set an amount in USDC and the wallet that receives it. Share the checkout link.

    Price29.00 USDC
    Pay toMerchant wallet
    Example
  2. 02

    The buyer pays USDC

    A person or an AI agent checks the terms and approves the payment from their own wallet.

    LinkSell is not in this path
  3. 03

    The merchant wallet receives it

    The USDC settles in your wallet. LinkSell records the payment for you.

The parts of a sale you control.

Each part works on its own. Use only the parts that your store needs.

Hosted checkout

One page shows the price, asset, network, and receiving wallet before the buyer approves.

Manage your store in plain words.

Connect an MCP client to your store. Your assistant reads your offers and prepares changes. Nothing changes until you confirm.

Paying is a separate thing.

An AI agent that buys from you pays the hosted checkout with its own wallet. It does not use your store tools.

The actions available depend on the tools and scopes that you grant.

Questions before you start.

What does it cost?

A flat monthly plan. LinkSell takes 0% of each sale. Network, wallet, or conversion costs can apply, and LinkSell does not set them.

Who receives the USDC?

The merchant wallet on the offer. The payment goes from the buyer wallet to that wallet. LinkSell is not in the path.

What does a buyer need?

A compatible wallet that holds USDC on the network in the offer. The checkout shows the amount, asset, network, and wallet before the buyer approves.

Can an AI agent pay?

Yes. An agent with its own wallet and signer can pay a hosted checkout or a paid API. It uses the same checkout as people. It is not a separate agent-to-agent payment product.

What does LinkSell not hold?

LinkSell does not hold buyer funds, merchant funds, or signing keys.

How do I leave?

Stop your plan. The payments that settled are already in your wallet, so there is nothing to withdraw from LinkSell.

Your checkout. Your wallet.

Set a price, share the link, and receive USDC. LinkSell takes 0% of each sale.
