It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum charge of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe provider, lowpaymentfee.com, hosts a broader catalog of pay-per-call APIs spanning data/analytics, AI/ML (sentiment, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, gas estimates), and infrastructure utilities (geocoding, validation, conversion). All endpoints appear to share the same $0.02/request pricing model on Base. However, the specific endpoint being listed here (/api/v1/employees/88) is not prominently documented on the provider's landing page, and no detailed schema or example response is available for it.\n\nDocumentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no response schema, and no example payloads available. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual data returned after payment 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","staff data","personnel endpoint","x402 micropayment API","pay-per-request data","lowpaymentfee"],"warnings":["The /api/v1/employees/88 endpoint is not listed on the provider's landing page among their advertised APIs","All documentation pages (/docs, /api, /pricing, /README) render only 'Connect wallet' with no content","No response schema or example response is available — the shape of returned data is unknown","The endpoint targets a hardcoded employee ID (88); it is unclear if other IDs are supported or what the data contains"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/88","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/88","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base).
