Project Information
At a Glance
AgentPay is a payment infrastructure that enables AI agents to discover, pay for, and consume API service autonomously using XRP on the XRPL. No API keys, no accounts, no human approval.
Description
Agent Pay is a decentralized API database for AI agents. Developers fund their agent's wallet with USDC, the agent autonomously discovers and pays for any registered service.
Businesses provide API on the platform and extend their market from humans-only to humans and AI agents in a few clicks. Every API becomes payable in seconds with crypto.

Technical Details
AgentPay implements the x402 protocol on the XRPL, to create an autonomous payment flow for ai agents. When an AI agent calls a paid API, the server returns a payment challenge; the agent signs an XRP transaction, retries with proof, and the server verifies it on-chain before serving the response.
The whole cycle takes under 5 seconds. No API keys, no accounts, no human approval. Every payment is real XRP on mainnet, verifiable on-chain. Built in TypeScript on Next.js with Context7 for live API documentation and Upstash Redis for persistence.
