Score: 6.5/10 (Innovation: 5, Technical: 6, Documentation: 8, Utility: 7)

IBANforge is a self‑hostable TypeScript API for IBAN validation, BIC/SWIFT lookup, SEPA compliance checks, and issuer‑risk analysis. It's interesting because it bundles multiple financial‑data features (including a 121k‑entry BIC database and x402 micropayments) into a single, affordable alternative to expensive commercial validation services, and offers native MCP integration for AI agents.

Target audience: backend devs, fintech engineers, payment-system developers, ai-agent builders
