AgentPay is a privacy-preserving payment protocol for AI agents. One agent wants something from another agent — data, a translation, a forecast, a credit check — and pays for it per query in USDC on Base L2, using the x402 payment standard. No accounts, no API keys, no subscriptions. Just a wallet, a signature, and a real settlement.
Machine-to-machine commerce has a payments problem. API keys and subscriptions are built for humans with browsers. AgentPay replaces them with the x402 flow: a paid endpoint answers a request with HTTP 402 plus machine-readable payment terms, the buying agent signs a payment authorization from its own wallet, and AgentPay's facilitator verifies the signature and settles the USDC transfer on Base L2. The endpoint then serves the answer.
The buyer never signs up for anything. The seller never issues a key. The settlement lands on-chain and both sides can verify it.
AgentPay is: a live x402 facilitator — free signature verification (/facilitator/verify), real USDC settlement on Base L2 (/facilitator/settle), spend authority enforcement, and a set of free pre-flight tools so buyers can check everything before money moves.
AgentPay is not: a token. There is no AgentPay coin, sale or presale — payments settle in USDC, a regulated stablecoin. And it is not a walled garden: the tools grade and work with any public x402 endpoint, including competitors'.
402 Payment Required with the terms: price, network (Base), payee address, and the facilitator that will settle it.Sellers get paid without building billing. Buyers pay only for what they actually use. Every settlement is a verifiable on-chain transaction.
Most "agent payments" demos are screenshots. AgentPay publishes its settlement pulse from real on-chain receipts — verified settlements only, never simulated. The current ledger:
Small numbers, honestly reported. The point is the rail: every cent moved through the same verification path an enterprise integration would use.
AgentPay's spend authority layer. A wallet owner signs a grant binding an agent wallet to a spend envelope — a budget per rolling hour, day or month, a no-confirm threshold, and an expiry. The facilitator enforces the grant before settlement, so an agent physically cannot spend past its budget or transact after its authority expires. Over-threshold purchases require the owner's explicit confirmation.
Curious whether a public x402 endpoint is even worth paying? The free Endpoint Report grades it from the buyer's side, and the market heat map shows which listed endpoints are actually payable right now.
Humans can use it too: the AgentPay Android app runs a personal agent, funds its wallet and shows its payments in plain English.
A payment protocol for AI agents that implements the x402 standard: the agent receives 402 terms, signs a payment with its wallet, and the AgentPay facilitator verifies and settles the payment in USDC on Base L2. No accounts, no API keys, no subscriptions.
No. AgentPay is a payment protocol and facilitator. Payments settle in USDC on Base L2. There is no AgentPay token, sale or presale.
x402 turns HTTP 402 into a real payment mechanism. A paid endpoint answers a request with 402 plus machine-readable payment terms; the buyer signs an EIP-3009-style authorization and delivers it in an X-Payment header; a facilitator verifies and settles on-chain; the endpoint serves the response.
The agent calls a paid endpoint, receives the 402 terms, signs the payment with its own Base wallet, and sends the signed header. The facilitator verifies the signature, checks the payer's authorization state and balance on-chain, settles the USDC transfer, and the endpoint returns the answer. Fully machine-to-machine.
The spend authority layer: the wallet owner signs a grant binding the agent wallet to a budget per rolling period, a no-confirm threshold and an expiry. The facilitator enforces it before settlement, so an agent cannot spend past its budget.
Yes — the AgentPay Android app runs a personal agent, funds its wallet and shows its payments. Humans can also grade public x402 endpoints and check payment readiness before buying.
Real. Every settled payment is an on-chain USDC transfer on Base L2 with a verifiable transaction hash, and the public settlement pulse counts verified settlements only.
