It is part of a broader platform that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/196/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: callers include an X-PAYMENT header with a signed payment proof, and the server returns the resource (application/json) upon successful verification. No API keys or rate limits are advertised; access is purely payment-gated.\n\nThe platform's landing page lists 16 endpoints across four categories (Data & Analytics, AI & Machine Learning, Finance & Web3, Infrastructure), all at the same $0.02 price point. However, the crawled documentation, pricing, and API pages returned only \"Connect wallet\" content with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no examples of what the order status response actually contains. The endpoint is live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know what payload to send or what response to expect.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","micropayment API","USDC payment API","pay-per-request","Base network API"],"warnings":["No OpenAPI or schema documentation available — request body and response format are unknown","Endpoint path is hardcoded to order 196; unclear if other order IDs are supported or how to discover them","All documentation, pricing, and API pages beyond the landing page returned only 'Connect wallet' with no content","The 'Premium API Access' label is generic and does not describe what the endpoint actually returns"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/196/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/196/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 402 challenge with clear pricing ($0.02 USDC on Base).
