It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, finance, crypto, and utility categories — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific resource `/api/v1/employees/185` returns JSON and accepts POST requests. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base mainnet, with a 300-second timeout window. No API keys or rate limits are required — access is purely payment-gated.\n\nDocumentation on the site is extremely thin: the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no description of what fields the employee record contains. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data payload and its structure are unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","pay-per-request","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 employee endpoint","pay-per-call API","USDC micropayment API","lowpaymentfee","Base USDC API"],"warnings":["No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content.","No request or response schema provided; the structure of the employee record is completely unknown.","No OpenAPI or ai-plugin manifest found.","The endpoint path '/api/v1/employees/185' is hardcoded to a single employee ID; it is unclear whether other IDs are supported or what the broader API surface looks like.","This endpoint does not appear in the site's own listed API catalog, which raises questions about its intended use."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/185","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/185","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live with a valid 402 challenge, but there is no documentation, no OpenAPI spec, no request/response schema, and no explanation of what the employee data contains.
