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/154/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 sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. No API keys or rate limits are advertised; access is instant upon payment.\n\nNote that this particular endpoint is scoped to a single order ID (154). The broader platform lists many other endpoints (analytics, AI sentiment/summarization/classification/embeddings, finance price feeds, crypto gas estimates, geocoding, validation, etc.) all at the same $0.02 price point. Documentation pages beyond the landing page returned only a \"Connect wallet\" prompt with no further technical detail, so the actual response schema and input parameters for this endpoint are unknown.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC pay-per-call","Base network API","lowpaymentfee","premium API access","order tracking"],"warnings":["Endpoint is hardcoded to order ID 154 — unclear if other order IDs are supported or how to discover them.","No OpenAPI spec, no request/response schema documentation available.","All documentation pages beyond the landing page returned only 'Connect wallet' with no useful content.","The broader platform lists many endpoints but none have documented schemas or examples."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/154/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/154/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 (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base).
