Score: 7.0/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 6)

Tenjin is a tool router for Claude Code that uses the Jev decision model to suggest the right external API tool at the right moment, paying for each call via the x402 micropayment protocol from a local USDC wallet. It eliminates the need for separate API keys or MCP servers, offering a curated catalog of tools with per-call pricing and configurable spending limits. The project combines agent orchestration, AI-based decision making, and blockchain payments into a novel developer utility.

Target audience: AI developers, backend engineers, devops, and Claude Code users
