The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network at $0.02 per call (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required; access is gated entirely by the x402 payment protocol.\n\nThe provider site (lowpaymentfee.com) hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per request. However, this specific endpoint exposes what appears to be personally identifiable information (an employee's SSN). The crawled documentation pages are essentially empty (showing only a \"Connect wallet\" prompt), so there is no further detail on request parameters, response schema, or data provenance.\n\nBecause this endpoint purports to serve Social Security Numbers — highly sensitive PII — users should exercise extreme caution. There is no documentation explaining the legitimacy of the data, whether it is synthetic/test data, or what legal framework governs its use. The endpoint is live and responds with a valid x402 challenge, but the nature of the data it claims to serve raises significant regulatory and ethical concerns.","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data","ssn-lookup","json-response","no-api-key","per-request-billing"],"categories":["data"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","employee data API","x402 data access","micropayment API"],"warnings":["Endpoint claims to serve Social Security Numbers (SSN) — highly sensitive PII.
