The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 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 broader lowpaymentfee.com platform advertises a wide catalog of x402-gated APIs spanning data & analytics, AI/ML inference (sentiment, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation), all priced at $0.02 per request. However, the specific endpoint being listed here (/api/v1/employees/145) is not documented on the site's landing page and its response schema is unknown. It is described only as \"Premium API Access\" in the x402 challenge. The endpoint is live and returning a proper 402 challenge.\n\nDocumentation is extremely thin — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no additional technical content. There is no OpenAPI spec, no example request/response, and no description of what fields the employee record contains. Callers should expect a JSON response but will need to discover the schema empirically.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","pay-per-request","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","staff record lookup","x402 employee endpoint","pay-per-call API","USDC API","Base network API","lowpaymentfee"],"warnings":["No OpenAPI or schema documentation available for this endpoint","The /api/v1/employees/145 path is not listed in the site's own API catalog","All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content","Response schema is completely unknown — callers must discover fields empirically","Only employee ID 145 is referenced; unclear if other IDs are accessible"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/145","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/145","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 works.
