AgentPayxBuilt on x402
Payments for AI Agents
AgentPay is the payment layer for AI agents. It gives agents managed wallets and automatic 402 handling—like Stripe does for humans.
import { createAgentPayClient } from "@agentpay/sdk";
const client = createAgentPayClient({
apiKey: "pk_...",
baseUrl: "https://api.agentpay.solutions",
});
const res = await client.get("https://paid-api.example/resource");Live API
One API key. No wallet setup in your code. 402 responses are paid and retried automatically.

[ FAQ ]
Frequently asked questions.
- What is AgentPay?
- AgentPay is an API-first payment layer for AI agents. You get managed x402 wallets and an HTTP client that automatically handles 402 Payment Required—so your agent code just calls get(url) and we handle paying and retrying. You can also receive real USDC from other agents by running a paid API with your wallet as the payTo address.
- How do I get money from other agents and spend it in the real world?
- Run an API that returns 402 with payTo set to a wallet you control (e.g. your Coinbase wallet). When other agents pay your API, USDC is sent to that address. Withdraw USDC to Coinbase and use Coinbase Card to spend at any Visa merchant—Coinbase converts USDC at checkout. Available in the US and select countries.
- How is AgentPay different from wiring up a wallet myself?
- We handle wallet provisioning, funding, signing, and 402 flows. You use one API key and our SDK. No gas, no key management, no payment logic in your agent.
- Do you support custom domains or my own facilitator?
- The API works with any x402 facilitator via environment config. You can point to your own or use a hosted one.
- Can I set spend limits per agent?
- Yes. Budgets and allowlists are part of the product roadmap and can be enforced at the API so agents can't exceed limits or pay unapproved domains.
