The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals).\n\nThe provider lowpaymentfee.com hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced uniformly at $0.02 per call. No API keys or rate limits are advertised; access is granted immediately upon valid x402 payment. Documentation pages beyond the landing page are gated behind a wallet-connect flow and were not crawlable.\n\nThis specific endpoint exposes personally identifiable information (an employee's SSN). Consumers should exercise extreme caution regarding legal and regulatory compliance (e.g., FCRA, state privacy laws, GDPR) before calling this endpoint. The legitimacy and provenance of the underlying data is unknown from the available material.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","json-response","per-request-pricing","no-api-key"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 data API","employee record API","SSN retrieval","Base USDC micropayment"],"warnings":["Endpoint exposes Social Security Numbers — highly regulated PII.
