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 pay-per-call APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this specific endpoint exposes what appears to be personally identifiable information (an employee's SSN), which raises significant regulatory and ethical concerns. There is no OpenAPI schema, no documentation beyond the landing page, and no example request/response bodies available from the crawled material.
