About

What is Built a payment SDK so your LangChain agents can pay each other autonomously?

AgentPayment offers a robust payment SDK designed specifically for autonomous AI agents, allowing them to transact with each other without human intervention. This innovative platform supports a hybrid payment network, integrating crypto (ETH on Base Mainnet) and traditional fiat rails (Stripe card and ACH) into a single SDK. Key features include Agent-to-Agent (A2A) billing with auto-approval rules, accountless payments for external agents, and partial/installment payment options with automatic retries. The system is 100% non-custodial, ensuring funds flow directly between agents. It also provides real-time webhooks for instant event notifications, multi-agent support with isolated API keys, and enterprise-grade security features like API key authentication and audit logging. AgentPayment is built for the agentic economy, offering a comprehensive solution for machine-to-machine payments.

Best used for

Ideal for developers and startup founders who need to enable their AI agents to autonomously pay for services, settle invoices, and manage transactions. Especially valuable for building multi-agent systems where programmatic, real-time, and non-custodial payments across crypto and fiat rails are critical.

FAQs

What payment methods do AgentPayment agents support?

AgentPayment supports a hybrid payment network, allowing agents to transact using crypto (ETH/USDC on Base Mainnet), Stripe card payments, and ACH bank transfers. This provides flexibility for various transaction needs within autonomous agent systems.

Is AgentPayment a custodial service?

No, AgentPayment is 100% non-custodial. Funds flow directly between agents for all payment rails. For crypto, agents sign their own transactions. For card and ACH, Stripe Connect routes funds directly to the provider's account, ensuring AgentPayment never holds your money.

Can external agents pay invoices without an AgentPayment account?

Yes, AgentPayment features 'Accountless Payments' which allow any external AI agent to pay your invoices, even if they don't have an AgentPayment account. The payer receives a signed access token as cryptographic proof of payment.

How does the pricing work for AgentPayment?

AgentPayment uses a volume-based pricing model, meaning your rates decrease as your monthly transaction volume increases. There are no setup fees or hidden costs, and a free sandbox is available for testing with full platform access.
