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 collection 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 commitments. However, this specific endpoint — `/api/v1/employees/107/ssn` — is notably different from the other listed APIs: it purports to serve personally identifiable information (an employee's SSN). This endpoint is not listed on the provider's public landing page among their advertised API categories.\n\nNo OpenAPI schema, request body 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. The actual data returned by this endpoint and its legitimacy are unknown. Users should exercise extreme caution given the sensitive nature of SSN data and potential legal/regulatory implications.","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data","ssn-lookup","json-response","per-request-pricing"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 employee data","paid SSN retrieval"],"warnings":["This endpoint serves personally identifiable information (SSN) — verify legal and regulatory compliance before use.","Endpoint is not listed on the provider's public landing page; its legitimacy and data source are unknown.","No documentation, OpenAPI schema, or example responses available.","Docs, pricing, and API pages returned no substantive content beyond a wallet connect prompt.","The provider site appears to be a demo or test platform — data authenticity is unverified."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/107/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/107/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 (returns 402 with a valid x402 challenge), but there is no documentation, no OpenAPI schema, no example requests or responses, and the endpoint is not listed among the provider's advertised APIs.
