The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network using the x402 \"exact\" scheme, with a maximum cost of $0.02 per request (20,000 base units of USDC at 6 decimals).\n\nThe provider lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific endpoint listed here is narrowly scoped: it serves SSN data for employee ID 160. There is no OpenAPI schema, no documentation beyond the landing page, and no example request/response bodies available from the crawl. The nature of the data returned (SSN) raises significant regulatory and privacy concerns — SSNs are highly sensitive personally identifiable information (PII) subject to laws such as the US Privacy Act, state data breach notification statutes, and potentially GDPR if EU persons are involved.\n\nBecause the crawled documentation pages (/docs, /api, /pricing, /README) all returned only a \"Connect wallet\" stub with no substantive content, the actual behavior, input parameters, and response format of this endpoint remain unverified. Prospective callers should exercise extreme caution given the sensitive data category.","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data","ssn-lookup","pay-per-call","json-response"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","employee data API","x402 SSN","micropayment data access"],"warnings":["This endpoint serves Social Security Numbers — highly sensitive PII.
