It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).\n\nThe provider lowpaymentfee.com hosts 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 specific endpoint falls under what appears to be a sample or demonstration resource (employees/119). No API keys or rate limits are advertised; callers simply attach an x402 payment header to each request.\n\nDocumentation is extremely sparse. The docs, pricing, API, and README pages all render 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 employee record contains or what POST body parameters are accepted. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data contract is unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","pay-per-call","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 API","pay-per-request API","USDC micropayment API","lowpaymentfee","Base network API"],"warnings":["No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'","No request or response schema provided; the data contract for employee records is entirely unknown","This appears to be a sample/demo resource (employees/119) rather than a production data service","No OpenAPI spec or ai-plugin manifest found"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/119","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/119","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 with clear pricing.
