It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, which spans data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities. All endpoints on the platform share a uniform $0.02 per-request pricing model, settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/employees/153` returns JSON (mimeType: application/json) and accepts POST requests. Payment is handled via the x402 protocol: callers receive a 402 challenge containing payment parameters, then submit a signed USDC payment (maxAmountRequired of 20,000 base units = $0.02 given USDC's 6 decimals) in the X-PAYMENT header. The payTo address is `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, and the accepted asset is USDC at contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base.\n\nDocumentation is extremely sparse — the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no description of request/response fields, and no examples of what the employee data payload looks like. The endpoint is confirmed live (402 challenge captured), but the actual data returned after payment is unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","pay-per-request","json-response"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 employee endpoint","lowpaymentfee API","pay-per-call data API","USDC micropayment API","Base network API"],"warnings":["No documentation available — docs, pricing, and API pages all show only 'Connect wallet' with no content","No OpenAPI or schema describing request parameters or response fields","Unknown what data the employee record actually contains","Single hardcoded employee ID (153) — unclear if other IDs are supported or what the broader employees API looks like"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/153","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/153","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, and pricing is clear ($0.02 USDC on Base).
