About This Project

68% of AI agent purchases fail due to broken merchant pages, anti-bot protections, and payment rejections. FinFix is autonomous middleware that sits between AI shopping agents and broken merchant infrastructure.

When a transaction fails, FinFix's 5-stage pipeline kicks in:

  1. DETECT — Probes the merchant endpoint and identifies the failure
  2. CLASSIFY — Claude Sonnet AI classifies the failure type (DATA_FIX, CHECKOUT_FIX, or PAYMENT_FIX)
  3. FIX — Applies the right fix autonomously (scrapes broken pages, bypasses anti-bot via Crossmint World Store, or reroutes payments through USDC rails)
  4. SETTLE — Settles payment in USDC on Solana via Crossmint Wallets API with escrow and 2% fee collection
  5. AUDIT — Logs a complete, immutable audit trail of every decision and transaction

No human in the loop. The agent's user gets their product, the merchant gets paid, and FinFix earns a 2% fee on every fix.

Built with n8n for workflow orchestration, Claude Sonnet for AI classification, Crossmint for USDC wallets and World Store checkout, and a React dashboard for real-time monitoring.
