Pay-per-use data and tools (x402)
The agent pays a small amount each time it uses a paid data source or tool. Your rules cap what it spends and which payment networks it can use.
Supported agents
Connect agents however they were built
Framework, custom code, Microsoft Copilot Studio, MCP, or a browser: however an agent was built, VeriProof checks its actions against your rules and records each decision the same way.
How was your agent built?
Find the closest match. Many teams use more than one.
On an agent framework such as LangGraph, CrewAI, or the OpenAI Agents SDK
- Connects with
- A ready-made VeriProof adapter for that framework
- VeriProof checks
- Requests to the AI model, use of tools, or a whole task, depending on the framework
In your own code, without a framework
- Connects with
- The VeriProof developer kit for TypeScript, Python, .NET, Java, Rust, or Go
- VeriProof checks
- Any AI request, tool use, or business action your developers choose
In Microsoft Copilot Studio
- Connects with
- VeriProof added to the agent, plus a check in the system that makes the change
- VeriProof checks
- Business actions, such as updating a loan, before the record changes
As an AI assistant connected through MCP (Model Context Protocol)
- Connects with
- VeriProof’s MCP connection
- VeriProof checks
- Proposed actions, limited to what the signed-in person may do
As an agent that clicks through a browser or desktop app
- Connects with
- VeriProof’s browser-agent tools, through MCP
- VeriProof checks
- The proposed click or entry, recorded with the screen it was based on
As an agent that pays with x402, pay.sh, AP2, or stablecoins
- Connects with
- The VeriProof developer kit, at the point where the agent pays
- VeriProof checks
- Each payment, before the wallet or provider moves money
On a platform with no VeriProof SDK
- Connects with
- The VeriProof API, plus a command-line tool for setup and exports
- VeriProof checks
- Any action the platform sends to VeriProof before carrying it out
Framework adapters by language
An adapter plugs into the agent framework your developers already use, so they don't have to add the check by hand at every step. 35 adapters are available today.

Agents that spend money
An agent that spends money needs a limit, and a person who approves the exceptions. VeriProof checks each payment before your wallet or provider moves any money, and sends anything over the limit to the budget owner.
pay.sh and Machine Payments Protocol
The agent picks a paid provider from a catalog. Rules check that the provider is verified and that the session stays under its cap.
Purchases on someone's behalf (AP2)
The agent checks out for a customer or employee. Your rules hold it to the payee, amount, and time limit that person approved.
Stablecoin supplier payments
The agent pays suppliers in stablecoins. Payments to new suppliers and large cross-border transfers go to your treasury team first.
Same record, six portals
Decisions from every agent reach the right portal
However an agent connects, its decisions land in portals built for the business owner, risk and compliance, governance engineers, developers, auditors, and administrators. Work moves between them through built-in handoffs.
An agent action needs a person
Reviewer with authority
A rule needs data the agent does not send
Developer
A governance engineer changes a rule for a production agent
Administrator or Compliance Officer
A control is not met
Assigned owner
A risk needs a business decision
Business Owner
An audit begins
Auditor
