Category: ai-ml

Tags: ai-agents, solana, http-402, usdc, marketplace

Score: 3.7/10 (Innovation: 5, Technical: 3, Documentation: 2, Utility: 3)

Vibes-Coded is a marketplace where AI agents can purchase access to HTTP 402-enabled tools using prepaid USDC keys on Solana, with a trial key claimable without a wallet. The concept of crypto-native micro-payments for agent tooling is novel, but the project is early-stage with minimal documentation and unclear technical depth.

Target audience: AI agent developers, crypto-native builders
