The provider operates a broad suite of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request and settled in USDC on the Base network. No API keys, rate limits, or upfront commitments are required — callers simply attach an x402 payment header to each request.\n\nThe specific endpoint probed (`/api/v1/orders/100/status`) appears to be an order-status lookup, though the provider's landing page does not list it among its featured API categories. The x402 challenge confirms the endpoint is live, accepting POST requests, and requiring up to 20,000 base units of USDC (0.02 USDC, i.e., $0.02) per call. Payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, with a 300-second timeout window.\n\nDocumentation is extremely thin — 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, and no usage examples available from the crawl. The endpoint's actual response format and the meaning of the order ID path parameter are unknown beyond what can be inferred from the URL structure.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-call","no-api-key","micropayment"],"categories":["commerce","infrastructure"],"synonyms":["order status API","order tracking","x402 API","micropayment API","Base USDC API","pay-per-request","lowpaymentfee"],"warnings":["No OpenAPI or schema documentation available — request and response formats are unknown.","Docs, API, pricing, and README pages all render only 'Connect wallet' with no usable content.","The /api/v1/orders/100/status endpoint is not listed among the provider's advertised API categories; its purpose and parameters are inferred solely from the URL.","No examples or integration guides found."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/100/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/100/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 captured) 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 specific endpoint is not listed among the provider's featured APIs.
