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 broad 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 endpoints are advertised at $0.02 per request with no API keys, no rate limits, and no minimum commitments. The specific endpoint probed here (/api/v1/employees/70) is not listed on the landing page catalog, suggesting it may be an unlisted or demo resource.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual data returned after payment is 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 API documentation available; /docs, /pricing, /api, and /README pages all show only 'Connect wallet'","No OpenAPI or schema definition found for this endpoint","The /api/v1/employees/70 path is not listed in the provider's public API catalog — may be a demo or unlisted resource","Response format and fields are entirely unknown; no example responses available"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/70","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/70","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live with a valid 402 x402 challenge, but documentation is essentially nonexistent — no OpenAPI spec, no request/response schemas, no examples.
