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 request with no API keys, no rate limits, and no minimum commitments. However, this specific endpoint — /api/v1/employees/96/ssn — is not listed on the provider's public landing page among the advertised API categories. It appears to serve sensitive personally identifiable information (an employee's SSN), which raises significant regulatory and ethical concerns.\n\nDocumentation is extremely sparse. The docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what input the POST body expects or what the response payload looks like beyond the stated mimeType of application/json.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","micropayment","post-endpoint"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","employee data API","x402 employee endpoint","SSN retrieval"],"warnings":["Endpoint serves personally identifiable information (Social Security Numbers) — significant regulatory risk under CCPA, GDPR, HIPAA, and other privacy laws.","This specific endpoint (/api/v1/employees/96/ssn) is NOT listed among the provider's publicly advertised APIs, raising questions about its legitimacy or intended audience.","No request or response schema is documented anywhere; integration requires blind experimentation.","All documentation pages (docs, API, pricing, README) returned only a 'Connect wallet' prompt with no usable content.","Hardcoded employee ID (96) in the URL — unclear if other employee IDs are accessible or if this is a demo."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/96/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/96/ssn","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request/response schema, no OpenAPI spec, no examples, and the endpoint is not listed on the provider's own landing page.
