The endpoint accepts POST requests and is settled in USDC on the Base network. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 per request.\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. This particular endpoint is part of what appears to be a demo or sample employee data API. No API keys or rate limits are advertised; access is granted purely through x402 payment. The response MIME type is application/json.\n\nIMPORTANT: This endpoint returns personally identifiable information (SSN). Consumers should exercise extreme caution regarding legal and regulatory compliance (e.g., FCRA, state privacy laws) before programmatically accessing or storing SSN data. The legitimacy and source of the underlying data is unknown from the available documentation.","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data","ssn-lookup","per-request-micropayment","json-response"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","x402 employee data","micropayment PII endpoint","Base USDC data API"],"warnings":["Endpoint returns personally identifiable information (SSN) — legal and regulatory compliance (FCRA, state privacy laws) is the caller's responsibility.","No documentation exists for request body format or response schema — behavior must be discovered empirically.","Data provenance is entirely unknown; it is unclear whether this is synthetic/demo data or real employee records.","The docs, pricing, and README pages on the provider site are effectively empty (only show 'Connect wallet').","This appears to be a demo or test platform; reliability and data authenticity are unverified."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/110/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/110/ssn","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base).
