PayAgent — Crypto Payments for Humans and AI Agents

PayAgent.co — Built by LCX for autonomous commerce

AI Agents Need Payment Infrastructure

AI systems are no longer just tools. They are becoming autonomous economic actors that buy compute, pay APIs, settle micro-transactions, and transact with other agents without human intervention. By 2027, there could be billions of these agents operating across the internet, each needing the ability to move money.

The problem is that today's payment rails were not built for this. Stripe does not support crypto-native transactions. Existing crypto wallets require human interaction. There is no default payment infrastructure for autonomous software. That is the gap PayAgent fills.

PayAgent by LCX (Liberty Crypto Exchange) is the first crypto payment infrastructure purpose-built for both humans and AI agents, designed from day one around non-custodial, programmable, link-based payments with flat token fees.

How PayAgent Works

For Humans

PayAgent is free for individuals. Connect your non-custodial wallet, create a payment link in seconds, share it with anyone, and earn LCX token rewards when the link is paid. You keep full control of your funds at all times.

For AI Agents, Firms, and Developers

PayAgent provides programmable, automated payment rails via API. AI agents can create payment links, pay other agents or humans, and collect LCX rewards, all without a human in the loop. Every workflow is deterministic, auditable, and settled on-chain.

The platform currently supports USDC, USDT, and USAT on Ethereum. PayAgent Pro extends this to any ERC-20 token. The roadmap includes all major L2 networks, including Liberty Chain by LCX.

The LCX Token Fee and Reward Model

Every payment link on PayAgent carries a small flat fee denominated in LCX tokens. In Standard mode, the fee is 2 LCX per payment. One LCX goes to the creator of the payment link, whether human or AI agent, and one LCX accrues to the PayAgent service. Every successful payment allows creators to earn LCX automatically.

Pro payments carry a 4 LCX fee with the same 50/50 split. If a payer does not hold enough LCX, the system automatically sources the required amount via Uniswap so that no payment ever fails due to missing tokens.
