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 suite 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 priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments required. Payment is handled entirely through the x402 protocol on the Base L2 network.\n\nThe specific endpoint `/api/v1/employees/82` appears to serve a single employee record. No OpenAPI schema, detailed documentation, or response examples were found in the crawl — the docs, pricing, and API pages all returned only a \"Connect wallet\" prompt with no substantive content. The exact fields returned in the employee JSON response are unknown.","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 — response format is unknown","Docs, pricing, and API pages all render only 'Connect wallet' with no substantive content","The endpoint serves a single hardcoded employee record (#82); unclear if other IDs are supported","No information on what fields the employee record contains"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/82","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/82","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge with clear pricing.
