Validly - One validation API
Validly solves the micropayment problem for API-based validation services. Traditional blockchain payment systems are too expensive for sub-dollar transactions due to gas fees that often exceed the payment amount itself. Our validation API calls range from $0.003 (email verification) to $0.95 (identity check), making standard blockchain payments economically unviable. I built Validly to demonstrate how Circle's payment infrastructure enables an entirely new class of micropayment-powered applications. By combining Circle Developer Controlled Wallets, Circle Gateway x402 nanopayments, and Arc testnet settlement, we created a production-ready platform where every API call is charged in real-time with USDC, settled in under a second, and fully auditable on-chain.
