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 gated behind x402 micropayments on the Base network.\n\nThe specific resource `/api/v1/employees/166` returns JSON and costs up to $0.02 per request (20,000 base units of USDC on Base, which uses 6 decimals). Payment is made via the x402 \"exact\" scheme by sending USDC to the specified payTo address. No API keys, rate limits, or upfront commitments are required — callers simply attach an X-PAYMENT header with a valid payment proof.\n\nDocumentation on the site is extremely sparse: the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data returned after payment is unknown. The endpoint path suggests it returns information about a specific employee entity, but the structure and fields of that response are not documented anywhere in the crawled material.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","employee-data","json-response","no-api-key","no-rate-limit"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 micropayment API","pay-per-call data","Base USDC API","lowpaymentfee","employee endpoint","402 payment API"],"warnings":["No OpenAPI spec or response schema available — actual response structure is unknown","Documentation pages (docs, pricing, API, README) all render only 'Connect wallet' with no content","The endpoint path '/api/v1/employees/166' is not listed on the provider's homepage among their advertised APIs, raising questions about whether it is a production resource","No information on what 'employee' data is returned or its source/accuracy"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/166","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/166","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 zero documentation on request parameters, response schema, or what employee data is actually returned.
