It is part of a broader platform (lowpaymentfee.com) 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/161/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 (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base), which equals $0.02 given USDC's 6 decimals. No API keys are required; access is granted per-call by including the X-PAYMENT header with a valid x402 payment proof. The platform advertises no rate limits and instant access.\n\nDocumentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no examples beyond the landing page's list of available endpoints. The endpoint is live (returns a proper 402 challenge), but the actual response payload for a paid request is unknown. The order-status endpoint appears to be a specific resource (order 161) rather than a general-purpose API, which limits its utility unless the caller knows the context of that order.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","pay-per-request API","Base USDC API","lowpaymentfee","402 payment endpoint","order tracking"],"warnings":["No documentation available — /docs, /api, /pricing, and /README pages all render only 'Connect wallet'","No OpenAPI or response schema provided; actual response format is unknown","Endpoint targets a specific order (#161) rather than a parameterized resource — unclear general utility","The platform lists many API categories on its landing page but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/161/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/161/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 and returns a valid x402 challenge, but documentation is essentially nonexistent — all doc pages show only 'Connect wallet'.
