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/168` returns JSON data when a valid x402 payment header is supplied. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (contract 0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. The endpoint accepts POST requests and is discoverable.\n\nThe platform advertises a uniform $0.02/request pricing model with no API keys, no rate limits, no minimums, and instant access. Documentation pages (/docs, /pricing, /README) appear to require a wallet connection and contain no substantive content in the crawl. Because of this, the actual response schema and the precise fields returned for the employee record are unknown — there is no OpenAPI spec, no example response, and no detailed documentation available.","tags":[],"capabilities":["x402-payment","usdc-micropayment","base-network","employee-data","json-response","pay-per-request","no-api-key"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 employee endpoint","micropayment API","pay-per-call data","Base USDC API","lowpaymentfee"],"warnings":["No OpenAPI or schema documentation available — response format for employee data is unknown","All doc pages (/docs, /pricing, /README) render only a wallet-connect prompt with no substantive content","The endpoint path suggests a single employee record (ID 168); it is unclear whether other IDs are available or what fields are returned","No rate limit or SLA information available"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/168","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/168","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge with clear pricing.
