what's x402scan?
x402scan is a cryptocurrency project operating within the x402 payments protocol ecosystem, developed by Coinbase. The x402 protocol facilitates internet-native payments built on HTTP standards, allowing resource servers and clients to handle micropayments seamlessly without deep crypto knowledge. It abstracts complexities like gas fees and RPC interactions into a facilitator layer, enabling minimal integration—often just one line of code for servers and a simple function for clients. This design prioritizes ease of use, aiming to make on-chain payments 10x more accessible than traditional methods. The project includes tools like Composer, which supports AI agents and ecosystem exploration, and scans for related initiatives such as pingobserver, heurist_ai, and others on chains like Base. x402scan focuses on growing the protocol's adoption by listing and promoting compatible projects, fostering a network for HTTP-based crypto transactions in web services, APIs, and file servers.
x402scan launched in 2025.
