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. This particular endpoint is part of what appears to be an employee data resource. However, the nature of the data returned (SSN) raises significant regulatory and ethical concerns. There is no documentation beyond the landing page describing what fields are returned, what input the POST body expects, or what authorization/compliance framework governs access to this sensitive personally identifiable information.\n\nThe endpoint is live and responds with a valid x402 challenge (HTTP 402). No OpenAPI schema, detailed docs, or example responses were found in the crawl. The docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content.","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data","ssn-lookup","pay-per-request","no-api-key"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","employee data API","SSN retrieval","x402 employee API"],"warnings":["Endpoint returns Social Security Number data — highly regulated PII.
