The specific resource `/api/v1/employees/124/salary` returns salary information for employee ID 124 when called with a POST request and a valid x402 payment header. Payment is settled in USDC on the Base network.\n\nThe endpoint charges a maximum of 0.02 USDC per request (20,000 base units with 6 decimals). The provider site lowpaymentfee.com hosts a broader catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per request. No API keys or rate limits are advertised; access is gated entirely through the x402 micropayment protocol.\n\nDocumentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary response contains. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data returned after payment is unknown.","tags":[],"capabilities":["x402-payment","usdc-base","employee-salary-data","pay-per-request","no-api-key"],"categories":["data"],"synonyms":["employee salary API","payroll data endpoint","x402 salary lookup","micropayment API","USDC gated API","Base network API","lowpaymentfee"],"warnings":["No API documentation available — all doc pages return only 'Connect wallet'","No OpenAPI or output schema provided; response format is completely unknown","The endpoint path suggests access to individual employee salary data, which may involve sensitive/regulated PII","This specific endpoint (/employees/124/salary) is not listed on the provider's homepage catalog — it may be a demo or test resource"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/124/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/124/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 and returns a valid x402 402 challenge, but there is no OpenAPI schema, no request/response examples, and all documentation pages are empty stubs showing only 'Connect wallet'.
