The endpoint 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 broader suite of pay-per-call APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are advertised at $0.02 per request with no API keys, no rate limits, and no minimum commitments required.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee endpoint accepts or returns. The endpoint is confirmed live (returns a proper 402 x402 challenge), but without documentation it is unclear what input the POST body should contain or what shape the response takes.","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","paid data endpoint","x402 employee data","Base USDC API","lowpaymentfee API","per-request employee data"],"warnings":["No documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content","No OpenAPI or schema definition; request body format and response shape are unknown","The specific data returned for employee #172 is undocumented — unclear if this is sample/demo data or a real dataset","Provider hosts many diverse API categories (AI, finance, geo, etc.) all at the same price, which may indicate a demo or placeholder site"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/172","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/172","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live with a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base).
