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 site lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, 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 endpoint path explicitly references SSN data, which raises significant regulatory and privacy concerns (PII handling, FCRA, state data-breach laws, etc.).\n\nDocumentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no information about what input the POST body expects or what the response payload looks like beyond the stated mimeType of application/json.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","per-call-micropayment","json-response"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","employee data API","x402 data access","Base USDC micropayment API"],"warnings":["Endpoint exposes Social Security Number data — highly regulated PII.
