This specific endpoint (`/api/v1/customers/73`) is listed as \"Premium API Access\" and returns JSON data when a valid x402 payment header is supplied. Payment is settled in USDC (contract 0x8335…2913 on Base) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals). No API keys, rate limits, or upfront commitments are required — each call is individually paid.\n\nThe broader lowpaymentfee.com platform advertises endpoints across several categories: Data & Analytics (metrics, reports, data export, insights), AI & Machine Learning (sentiment analysis, text 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.\n\nThe specific `/api/v1/customers/73` endpoint appears to be a customer-record lookup, but the crawled documentation is extremely thin — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the customer object contains. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know exactly what data is returned.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","per-request-billing","json-response","customer-data-lookup","no-api-key"],"categories":["data","api-marketplace"],"synonyms":["x402 API","pay-per-call API","USDC micropayment API","Base network API","customer lookup API","lowpaymentfee","402 payment protocol"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","Docs, API, pricing, and README pages all render only 'Connect wallet' with no usable content","The specific purpose and fields of /api/v1/customers/73 are undocumented","This may be a demo/showcase site rather than a production data provider"],"endpointUrl":"https://lowpaymentfee.com/api/v1/customers/73","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/customers/73","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 402 challenge and clear pricing ($0.02 USDC on Base).
