It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/187/status` is labeled \"Premium API Access\" in the x402 challenge. The payment is settled on-chain using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a max amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The platform advertises no API keys, no rate limits, and instant access — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\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 schema, no request/response examples, and no detailed description of what the order status response contains. The endpoint is confirmed live (402 challenge returned), but the actual functionality behind the paywall is unverifiable from available material.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","order-status","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 endpoint","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["No OpenAPI schema or API documentation available — all doc pages render only 'Connect wallet'","Endpoint is hardcoded to order ID 187; unclear if this is a demo or a real resource","No request body schema or response schema provided; actual response format is unknown","The broader platform lists many endpoints but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/187/status","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/orders/187/status","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no request/response examples, and the endpoint path is hardcoded to a single order ID (187), making its general utility unclear.
