The specific resource `/api/v1/employees/125/ssn` returns SSN information for employee ID 125 in JSON format. 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, and utility services, all priced at $0.02 per call. The platform advertises no API keys, no rate limits, and instant access — callers simply attach an x402 payment header to each request. The endpoint accepts POST requests and returns application/json responses.\n\nDocumentation is extremely sparse: the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The nature of the data (employee SSN) raises significant regulatory and privacy concerns — SSNs are highly sensitive PII governed by laws such as the Privacy Act, GLBA, and various state data breach statutes. Callers should exercise extreme caution and verify the legitimacy and legal compliance of this data source before use.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","json-response","per-request-pricing"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 employee data","Base USDC micropayment API","sensitive data API"],"warnings":["This endpoint exposes highly sensitive PII (Social Security Numbers).
