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 range of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request. However, this specific listing is for the `/api/v1/employees/154` path, which is described only as \"Premium API Access\" with no further documentation on the response schema or the nature of the employee data returned. The docs, pricing, and README pages on the site are gated behind a wallet-connect flow and provide no additional detail.\n\nBecause there is no OpenAPI spec, no response schema, and no documentation beyond the generic landing page, the exact fields and structure of the employee record are unknown. 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","employee data endpoint","x402 employee","pay-per-call data API","lowpaymentfee employee"],"warnings":["No OpenAPI or response schema available — the structure of the returned employee data is unknown","All documentation pages (docs, pricing, README) are behind a wallet-connect gate and provide no content","The specific purpose and data fields of /api/v1/employees/154 are undocumented","No examples of request body or response body are available"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/154","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/154","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no response schema, no documentation beyond a generic landing page, and the purpose of the employee data is unexplained.
