The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum amount of 20,000 base units, which equals $0.02 USD (USDC uses 6 decimals). No API keys or rate limits are required — access is gated purely 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. Documentation pages exist but appear to require wallet connection and contain no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed documentation for this specific endpoint. The endpoint path strongly suggests it returns personally identifiable information (an employee's SSN), which raises significant regulatory and ethical concerns around PII handling, data provenance, and compliance with laws such as the FCRA, GLBA, and state privacy statutes.\n\nThe x402 challenge was successfully captured (HTTP 402 with valid accepts array), confirming the endpoint is live. However, the lack of documentation about what data source backs this endpoint, how the data was obtained, and what legal basis exists for its sale is a serious red flag.","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data-lookup","ssn-retrieval","json-response","no-api-key","per-request-billing"],"categories":["data","pii"],"synonyms":["social security number lookup","employee SSN API","PII endpoint","employee record API","SSN retrieval service","x402 data API"],"warnings":["CRITICAL: This endpoint claims to return Social Security Numbers (PII).
