It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, all gated behind the x402 payment protocol. The endpoint accepts POST requests and returns JSON.\n\nPayment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge advertises a maxAmountRequired of 20000 base units, which at 6 decimals for USDC equals $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing model across all their endpoints, with no API keys, no rate limits, and no minimum commitments required.\n\nThe endpoint is live and returning a valid x402 challenge (HTTP 402). However, the nature of the data returned — employee SSN — raises significant concerns. SSNs are highly sensitive personally identifiable information (PII) subject to strict regulatory requirements in the United States. There is no documentation explaining whether this is synthetic/test data, a legitimate authorized data service, or something else entirely. The docs, pricing, API, and README pages on the site all render only a \"Connect wallet\" prompt with no substantive documentation. Prospective users should exercise extreme caution and verify the legitimacy and legality of this data before use.","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data-lookup","ssn-retrieval","pay-per-request","json-response"],"categories":["data","pii"],"synonyms":["employee SSN lookup","social security number API","employee data endpoint","PII retrieval API","x402 data access","Base USDC micropayment API"],"warnings":["This endpoint claims to return employee SSN data — highly sensitive PII regulated under US federal and state law.
