X402scan is built by Merit Systems and is listed on Merit Systems' official site as a core part of the x402 ecosystem. The x402 standard works by using HTTP 402 Payment Required responses to prompt clients to pay and retry requests, enabling agentic and machine-to-machine payments that settle in stablecoins such as USDC. The protocol is production-ready, open-source, and security-audited, supporting EVM-compatible chains, Solana, and additional networks.

X402scan functions as a marketplace where merchants and API providers list priced endpoints that can be discovered and consumed by autonomous agents. AgentCash documentation describes X402scan as the designated registry for x402 discovery, directing API providers to register there so their services become agent-accessible. The AgentCash index covers priced endpoints settling on Base, Solana, and Tempo, with a median price of $0.028 per call. X402scan also works in conjunction with Poncho, enabling agents to use x402 endpoints directly. Merit Systems, the team behind X402scan, raised $10 million from a16z crypto, Blockchain Capital, and industry angels, and holds General Member status within the x402 ecosystem, which operates under Linux Foundation Projects.
