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 with 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 being listed here is narrowly scoped: it serves SSN data for employee 104. No documentation beyond the landing page is available (docs, pricing, and README pages all render only a wallet-connect prompt with no substantive content).\n\nBecause this endpoint returns personally identifiable information (SSN), consumers should exercise extreme caution regarding legal and regulatory compliance (e.g., FCRA, state privacy laws, GDPR if applicable). The provenance and legitimacy of the underlying data is unknown from the available materials.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","pay-per-call","json-response"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 employee data","micropayment SSN","Base USDC API"],"warnings":["Endpoint returns personally identifiable information (SSN) — verify legal/regulatory compliance before use.","Data provenance is completely unknown; no documentation explains where employee data originates.","No OpenAPI schema or response examples available — request/response format must be discovered empirically.","Documentation pages (docs, pricing, README) contain no substantive content.","Single hardcoded employee ID (104) in the path — unclear if other IDs are supported.","Potential FCRA, state privacy law, and GDPR implications for SSN data access."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/104/ssn","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/employees/104/ssn","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base).
