Capri Ai Agentpay

Capri Agentpay is the first governed payment layer purpose-built for AI agents operating in production environments. As autonomous agents increasingly call paid APIs, settle transactions, and interact with stateful systems, the traditional approach of handing them a private key introduces a critical security vulnerability. A single bad prompt or misaligned instruction can drain an entire wallet before a human can intervene. Capri Agentpay solves this by placing a policy-enforced runtime directly between the agent and the signer. The agent interacts with a single typed surface, and when it encounters an HTTP 402 Payment Required challenge, Capri Agentpay evaluates a fixed sequence of policies: merchant allowlist, per-transaction cap, daily budget, and an auto-approve threshold that can pause for human review. Only when every check passes does the system settle the payment, retry the original request with cryptographic proof attached, and store a signed receipt that can be verified offline. This product is designed for engineering teams shipping agent systems that need real controls around money, approval workflows, and operator oversight. It provides six MCP tools instead of raw key access, a VS Code extension for seamless integration, and a Base Sepolia sandbox for settlement testing. Agents never hold your keys. Every payment is policy-checked before a signature ever exists, giving teams the confidence to move from fear to shipping in days.

x402 Payment Handling

Capri Agentpay natively intercepts HTTP 402 Payment Required challenges that agents encounter when calling paid APIs or MCP tools. Instead of failing or exposing raw credentials, the system automatically routes the challenge through its policy engine. It evaluates the request against configured rules, settles the payment on the appropriate chain, and retries the original request with proof of payment attached. This eliminates the need for developers to build custom payment handling logic into every agent workflow.

Per-Agent Budgets and Caps

Every agent operating under Capri Agentpay is assigned a dedicated budget with configurable per-transaction caps and daily spending limits. These boundaries are enforced at runtime, preventing any single agent from exceeding its allocated resources even if a prompt goes rogue or a loop spins out of control. Teams can set granular policies for different agent roles, ensuring that research agents, trading agents, and internal tool agents all operate within their defined financial guardrails.

Merchant Allowlists and Human-in-the-Loop Approvals

Capri Agentpay provides a merchant allowlist that restricts which endpoints or services an agent can pay. Only approved merchants can receive funds, adding a critical layer of access control. For transactions that exceed a configurable auto-approve threshold, the system pauses execution and surfaces a clear review queue to a human operator. The operator sees the exact amount, asset, chain, and recipient before making a decision, ensuring that high-value payments always receive human oversight.

Verifiable Receipts and Offline Verification

Every successfully settled payment generates a signed receipt that includes hashes, timestamps, and verification fields. These receipts can be verified offline, providing a cryptographic audit trail for every transaction an agent performs. This feature is critical for security teams, compliance requirements, and post-incident analysis. Operators can independently confirm that a payment was made, to whom, under which policy branch, and on which block, without needing to trust the system state.

Autonomous Research Agents Calling Paid APIs

Research teams deploying agents that query premium data APIs, such as financial market feeds, scientific databases, or proprietary knowledge graphs, can use Capri Agentpay to manage costs securely. The agent can call any approved endpoint, and the system automatically handles payment challenges within budget constraints. Human operators set daily limits and receive alerts when spending approaches thresholds, preventing unexpected bills while enabling continuous autonomous research.

Internal Tool Orchestration with Cost Controls

Enterprise teams building agents that interact with internal paid services, such as cloud compute instances, data transformation pipelines, or third-party monitoring tools, need strict cost governance. Capri Agentpay allows each agent to have a dedicated budget, preventing one runaway workflow from consuming shared resources. The merchant allowlist ensures agents can only pay approved internal services, while the human-in-the-loop approval catches any anomalous high-value requests.

Decentralized Application Agent Payments

Teams building agents that interact with decentralized applications, such as on-chain data oracles, NFT marketplaces, or DeFi protocols, can use Capri Agentpay to handle gas fees and transaction costs. The Base Sepolia sandbox allows teams to test settlement logic without real funds, while the signed receipts provide a verifiable record of every on-chain interaction. This enables agents to participate in decentralized ecosystems with the same security controls as centralized API calls.

Multi-Agent Systems with Shared Budget Pools

Organizations deploying multiple agents that share a common budget pool need granular allocation and tracking. Capri Agentpay supports per-agent budgets and caps within a shared pool, allowing teams to allocate resources dynamically. A lead agent might have a higher daily cap for complex research tasks, while supporting agents have lower limits for routine queries. The policy engine ensures no single agent can drain the pool, and the operator dashboard provides a clear view of spending across the entire agent fleet.

How does Capri Agentpay prevent an agent from draining a wallet?

Capri Agentpay places a policy-enforced runtime between the agent and the signer. The agent never holds a private key. Every payment request is evaluated against a fixed policy sequence: merchant allowlist, per-transaction cap, daily budget, and auto-approve threshold. Only when every check passes does a signature get created. This means even a malicious prompt cannot authorize a payment that violates any of these rules.

What happens when a payment exceeds the auto-approve threshold?

When a payment request exceeds the configurable auto-approve threshold, Capri Agentpay pauses execution and surfaces the request to a human operator. The operator sees the exact amount, asset, chain, and recipient before approving or denying the payment. This human-in-the-loop mechanism ensures that high-value transactions always receive manual review, preventing automated errors or unauthorized spending.

Can I use Capri Agentpay with existing agent frameworks?

Yes, Capri Agentpay is designed to integrate with existing agent frameworks through its six MCP tools and a VS Code extension. The agent interacts with a single typed surface, and the system handles payment challenges transparently. The Base Sepolia sandbox allows you to test settlement logic without real funds, making it easy to add payment controls to any agent workflow without rewriting your entire architecture.

How do verifiable receipts work and why are they important?

Each settled payment generates a signed receipt containing hashes, timestamps, and verification fields. These receipts can be verified offline using standard cryptographic tools, providing an immutable audit trail. This is critical for security teams that need to independently confirm transactions, for compliance requirements that mandate auditable records, and for post-incident analysis where you need to trace exactly what happened and under which policy branch.
