Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint requires no API keys, no rate limits, and provides instant access — callers simply attach an x402 payment header to authorize each call.\n\nThe hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. This particular endpoint sits under what appears to be a sample or demonstration HR/employee data resource. The x402 challenge was successfully captured (HTTP 402 with valid accepts payload), confirming the endpoint is live.\n\nDocumentation is extremely sparse — the docs, pricing, API, and README 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 exact structure of the POST body and the response format are unknown. Callers should expect a JSON response (mimeType is application/json) but will need to experiment to determine the precise schema.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","pay-per-call","no-api-key","json-response"],"categories":["data","finance"],"synonyms":["employee salary API","payroll data endpoint","HR data API","x402 employee endpoint","pay-per-request salary","lowpaymentfee API","Base USDC API"],"warnings":["No OpenAPI or schema documentation available — request and response formats are unknown","Docs, pricing, API, and README pages all render only 'Connect wallet' with no technical content","Endpoint path references a specific employee ID (47); unclear if other IDs are supported or if this is a demo","The nature and source of the 'salary' data is unverified — could be synthetic/demo data"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/47/salary","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/47/salary","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the endpoint path (employees/47/salary) appears to be a single hardcoded resource with unknown utility.
