It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, all gated behind the x402 payment protocol. Payment is settled in USDC on the Base network.\n\nThe x402 challenge confirms the endpoint is live and accepts POST requests. The maxAmountRequired is 20000 base units of USDC (which uses 6 decimals), equating to $0.02 per request. The provider advertises a flat $0.02/request pricing across all their endpoints, with no API keys, no rate limits, and instant access. No OpenAPI schema, detailed documentation, or example responses were found in the crawl — the docs, pricing, and API pages all returned only a \"Connect wallet\" prompt with no substantive content.\n\nThis endpoint raises significant concerns. It purports to return personally identifiable information (an SSN), which is highly regulated data in the United States. There is no indication of authorization controls, data provenance, compliance with privacy regulations (e.g., FCRA, GLBA, state privacy laws), or whether the data is synthetic/demo versus real. Consumers 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"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","employee data API","SSN retrieval service","x402 data endpoint"],"warnings":["Endpoint purports to return Social Security Numbers (PII) — highly regulated data in the US.
