Score: 7.5/10 (Innovation: 8, Technical: 8, Documentation: 7, Utility: 7)

Pay.sh is a Rust-based CLI tool that transparently handles HTTP 402 payment challenges for stablecoin-gated APIs on Solana, enabling autonomous payment flows for both humans and AI agents. It combines multiple payment protocols (x402 and MPP), biometric authorization, and an MCP server for AI integration, making it a novel infrastructure layer for monetized API access.

Target audience: backend devs, devops, ai-engineers
