It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, finance/Web3, and utility categories — all priced at $0.02 per request settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/195/status` is described generically as \"Premium API Access.\" The x402 challenge confirms it is live, accepting USDC (contract 0x8335…2913 on Base) with a max amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). Payment is made via the `exact` scheme to address 0x1A2B…85F3 with a 300-second timeout. No API key or account registration is required — callers simply attach an X-PAYMENT header conforming to the x402 protocol.\n\nDocumentation on the site is extremely thin: the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema beyond the x402 challenge's `outputSchema` stub, and no explanation of what fields the order-status response contains. The platform advertises no rate limits and instant access, but these claims cannot be independently verified from the crawled material.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","order-status","micropayment","no-api-key","post-endpoint"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 micropayment","USDC pay-per-call","Base network API","lowpaymentfee","premium API access","order tracking"],"warnings":["No OpenAPI or schema documentation available — request and response formats are unknown.","Docs, pricing, API, and README pages all return only 'Connect wallet' with no technical content.","Endpoint path is hardcoded to order ID 195; unclear if this is parameterizable or a demo.","Platform claims 'no rate limits' but this is unverifiable from available material.","The broader platform lists many endpoints (AI, finance, utils) but none have documented schemas."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/195/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/195/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 OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the endpoint path is hardcoded to a single order ID (195), making its general utility unclear.
