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 site lowpaymentfee.com hosts a broad catalog of x402-gated API endpoints spanning data analytics, AI/ML inference, finance, and utility services, all priced uniformly at $0.02 per call. No API keys or rate limits are advertised; access is granted purely through the x402 payment protocol. The site's documentation, pricing, and README pages appear to be stub pages showing only a \"Connect wallet\" prompt, so there is no detailed schema or usage documentation available beyond what the x402 challenge itself provides.\n\nThis specific endpoint exposes personally identifiable information (an employee's SSN). Consumers should exercise extreme caution: accessing, storing, or transmitting SSNs is subject to strict regulatory requirements (e.g., FCRA, state privacy laws, GDPR-adjacent rules). The legitimacy and legality of this data source is unverified. There is no documentation explaining the provenance of the data, consent mechanisms, or compliance posture.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","per-request-micropayment","json-response"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 data API","Base USDC micropayment API","employee record API"],"warnings":["CRITICAL: This endpoint claims to expose Social Security Numbers — a highly regulated category of PII.
