What is getting in the way
A prototype can answer well and still fail as a business. It has no durable customer identity, access rules, revocation, usage boundary, checkout, or reliable place for customers to return.
Paid Agent
Monetize AI agents without building a SaaS backend
Prostir helps you monetize AI agents through owned behavior, controlled customer access, a stable endpoint, and supported payment paths around the product.
What changes
Publish one Agent, decide who can use it, define the paid offer, and connect supported seller-owned payments without building a separate subscription backend first.
Paid Agent
How Prostir gets you there
Finish the Agent promise
Define the exact customer job, knowledge, tools, and boundaries before adding a price.
Set access and the offer
Choose OAuth or an explicit API-key path, then prepare a free, one-time, or subscription offer where supported.
Connect seller payments
Use Stripe Connect for one-time or subscription sales, or Rozetka Pay for a supported one-time sale, then publish the customer path.
Early access
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.
