The provider operates a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all gated via the x402 protocol on the Base network. Each request costs $0.02 in USDC (USD Coin) with no API keys, rate limits, or subscriptions required.\n\nThe specific resource `/api/v1/employees/195` is labeled \"Premium API Access\" and accepts HTTP POST requests. It returns `application/json` content. The x402 challenge confirms the endpoint is live, advertising a maxAmountRequired of 20,000 base units of USDC (6 decimals → $0.02) on Base, payable to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. The payment timeout is 300 seconds.\n\nDocumentation is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no description of what fields the employee record contains. The endpoint's purpose and response structure must be inferred entirely from its URL path and the x402 challenge metadata.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","pay-per-request","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 employee endpoint","lowpaymentfee API","pay-per-call data API","Base USDC API"],"warnings":["No OpenAPI or schema documentation available — response structure is unknown","Docs, API, pricing, and README pages all render only 'Connect wallet' with no content","The specific endpoint /api/v1/employees/195 is not listed on the provider's homepage catalog, raising questions about its intended use","No information on what fields an employee record contains or what POST body is expected"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/195","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/195","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no indication of what the employee record actually contains.
