The endpoint accepts POST requests and is settled in USDC on the Base network. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 per request.\n\nThe provider lowpaymentfee.com hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per call with no API keys, no rate limits, and no minimum commitments. However, this specific endpoint exposes personally identifiable information (an employee's SSN), which raises significant regulatory and ethical concerns. No documentation, request/response schema, or usage examples are available beyond the x402 challenge and the landing page listing.\n\nThe endpoint is live and returns a proper 402 challenge. Payment is made via the x402 exact scheme to wallet 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base.
