The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (USD Coin) 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, crypto, and utility services — all priced at $0.02 per call with no API keys, no rate limits, and no commitments. The specific endpoint listed here is not featured on the provider's public landing page, which raises questions about whether it serves real PII or is a demo/test endpoint. The endpoint path (`/api/v1/employees/30/ssn`) strongly implies it returns personally identifiable information (a Social Security Number), which carries significant legal and regulatory implications.\n\nThe x402 challenge was successfully captured with a 402 response, confirming the endpoint is live. No OpenAPI schema, detailed documentation, or example responses were found in the crawl. The docs, pricing, and API pages all returned only a \"Connect wallet\" prompt with no substantive content.","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data-lookup","ssn-retrieval","json-response","per-request-micropayment"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 data API","employee record API","SSN retrieval service"],"warnings":["Endpoint path implies it returns a Social Security Number (PII) — handling SSN data is subject to strict legal and regulatory requirements (CCPA, GLBA, state breach notification laws, etc.).","This specific endpoint is NOT listed on the provider's public landing page, raising questions about whether it is a demo, test, or legitimate production endpoint.","No documentation, OpenAPI schema, or example responses are available — the actual response format is unknown.","No evidence that the provider has appropriate data handling, security, or compliance certifications for PII.","Docs, pricing, and API pages returned only 'Connect wallet' with no substantive content."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/30/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/30/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), but there is no documentation, no OpenAPI schema, no example responses, and the endpoint is not listed on the provider's own landing page.
