It 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 catalog of pay-per-call APIs spanning data & analytics, AI/ML inference (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 uniformly priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments required.\n\nDocumentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The specific data returned by the /api/v1/employees/118 endpoint is unknown beyond the stated mime type of application/json. The endpoint is confirmed live via a valid 402 challenge.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","json-api","pay-per-call","no-api-key"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 data API","pay-per-request API","USDC micropayment API","lowpaymentfee","Base network API"],"warnings":["No OpenAPI or schema documentation available; request and response formats are unknown.","All documentation pages (/docs, /api, /pricing, /README) render only 'Connect wallet' with no technical content.","The specific data returned by /api/v1/employees/118 is undocumented; 'employee data' is inferred from the URL path only.","This endpoint targets a single hardcoded employee ID (118); it is unclear if other IDs are supported or how to discover them."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/118","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/118","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 with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
