It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all gated behind x402 micropayments on the Base network using USDC.\n\nThe specific resource `/api/v1/employees/136` returns JSON (MIME type application/json) and is accessed via HTTP POST. Payment is settled on-chain on Base to the address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The payment timeout is 300 seconds.\n\nDocumentation is extremely sparse. The crawled docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee record contains. The endpoint is confirmed live (402 challenge returned), but the actual data payload and its usefulness are unknown. The platform advertises no API keys, no rate limits, and instant access across all its endpoints.","tags":[],"capabilities":["x402-payment","usdc-micropayment","base-network","employee-data","pay-per-request","json-response"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 employee endpoint","micropayment API","pay-per-call data","lowpaymentfee API","Base USDC API"],"warnings":["No documentation available — docs, pricing, API, and README pages all render only 'Connect wallet'","No OpenAPI or schema describing request parameters or response fields","Endpoint targets a single hardcoded employee ID (136); unclear if other IDs are available or what data is returned","The 'Premium API Access' title is generic and does not describe the actual data served"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/136","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/136","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 via a valid 402 challenge with clear pricing ($0.02 USDC on Base).
