Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint returns JSON and requires no API keys, rate limits, or upfront commitments — callers simply attach an x402 payment header to each request.\n\nThe broader lowpaymentfee.com platform hosts a variety of pay-per-call APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints share the same $0.02/request pricing model and settle on the Base network via x402.\n\nDocumentation is extremely sparse — the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary endpoint accepts or returns. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know what request body to send or what response shape to expect.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-salary-data","pay-per-call","no-api-key","json-response"],"categories":["data","finance"],"synonyms":["employee salary API","payroll data endpoint","salary lookup","x402 API","micropayment API","Base USDC API","lowpaymentfee"],"warnings":["No API documentation available — docs, pricing, and API pages all show only 'Connect wallet'","No OpenAPI or JSON schema describing request body or response format","The endpoint path references a specific employee ID (181); it is unclear whether other IDs are supported or what data is returned","The nature and source of the 'salary' data is undocumented — could be mock/demo data"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/181/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/181/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, confirming it accepts payments on Base in USDC at $0.02/call.
