Prostir

Paid Agent

Monetize AI agents with access you control

Monetize AI agents by offering a useful, tested service with clear access terms. Build the agent in Prostir and use your own eligible payment-provider account to charge for access.

For the usual MCP path, model-token cost to the Agent creator is $0: the customer's AI client supplies the model under that customer's subscription and limits.

What is getting in the way

A promising demo still needs a dependable service, a way for buyers to sign in and an offer they understand.

What changes

A published Agent with an explicit offer, verified access and a supported seller-owned payment path.

Paid Agent

How Prostir gets you there

  1. Define what people buy

    Say who the agent helps, what it can do and which requests remain outside the offer.

  2. Build and test the service

    Use Builder to configure the agent, sources and authorized tools. Test the experience a buyer will actually receive.

  3. Configure paid access

    Use eligible Stripe Connect one-time or subscription access, or one-time UAH payments through Rozetka Pay in Ukraine. Check checkout and access before launch.

What you can verify

  • Published Agents have controlled access, usage limits, and a stable HTTPS identity with an MCP endpoint.
  • Stripe Connect supports one-time and subscription Agent sales through the creator's seller account.
  • Rozetka Pay supports one-time marketplace sales; subscription entry points remain unavailable and fail closed.

A good fit if

  • You have a bounded Agent outcome that customers can understand and value.
  • You want to sell access while keeping the Agent configuration under creator control.

Not the right fit if

  • You need pay-per-use billing, a multi-seller marketplace, or an unsupported payment provider.
  • You expect payment setup alone to create demand or guarantee revenue.

Questions before you decide

Can I charge a subscription?

Yes through the supported Stripe Connect marketplace path. Rozetka Pay is one-time only and must not be presented as a subscription option.

Do customers get control of the Agent after buying?

No. They receive the allowed use of the published Agent. Instructions, tools, Skills, shared resources, and Agent Knowledge remain controlled by the creator.

Who pays for model tokens, and what do they cost the Agent creator?

For the usual MCP path, model-token cost to the Agent creator is $0. When a customer uses the Agent through a supported MCP connector in ChatGPT or Claude, the model runs in that customer's AI environment under the customer's subscription and limits. The creator pays for the Prostir plan, not those model tokens. AI Credits are needed only when the creator separately chooses a Prostir-hosted model run, such as a supported channel or widget. BYOK is optional and bills the creator's own provider account. Paid external tools remain separate.

How can I sell access?

Offer free access, a one-time purchase or a subscription through supported Stripe Connect options; Rozetka Pay supports one-time UAH payments in Ukraine. You can also restrict access to specific clients or companies, and you remain the seller responsible for payments and obligations to buyers. Funds go through your seller account, without Prostir holding them; any Prostir fees and payment-provider fees are separate, and self-service Prostir plans are billed monthly.

Build something worth paying for.

You know the expertise. The question is whether your agent helps someone enough to pay for access. Test the experience first, then configure eligible paid Agent access through your seller account. Start your 7-day Creator trial, no card needed.
