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 and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/9/status` is labeled \"Premium API Access\" in the x402 challenge. The payment scheme is \"exact\" with a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 protocol's X-PAYMENT header, with no API keys or rate limits required. The timeout for payment settlement is 300 seconds.\n\nThe platform's landing page advertises a uniform $0.02/request pricing model with no minimums, no commitments, and no API keys. Documentation pages (/docs, /pricing, /api, /README) all appear to require wallet connection and contain no further content. There is no OpenAPI schema, no detailed request/response documentation, and no examples available. The endpoint is confirmed live (returns HTTP 402 with a valid x402 challenge).","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 endpoint","micropayment API","USDC payment API","Base network API","pay-per-request","lowpaymentfee"],"warnings":["No OpenAPI or response schema available — response format is unknown","Documentation pages (/docs, /pricing, /api, /README) are all empty or wallet-gated","This endpoint is hardcoded to order ID 9; unclear if other order IDs are supported at different paths","No information about what 'order' refers to in this context","The platform lists many other endpoints on its landing page but this specific orders endpoint is not among them"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/9/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/9/status","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 challenge with clear pricing.
