It is part of a broader platform offering dozens of pay-per-call API endpoints 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.\n\nThe specific endpoint `/api/v1/orders/137/status` appears to be an order-status lookup. The x402 challenge confirms it is live, accepting payment of up to 20,000 base units of USDC (0.02 USD) on Base to address 0x1A2B…85F3. No API keys or rate limits are required; callers simply attach an X-PAYMENT header with a valid x402 payment proof. The response MIME type is application/json.\n\nDocumentation on the site is extremely thin — the docs, pricing, API, 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. The endpoint path suggests it returns order status information, but the exact fields and semantics are unknown. The platform advertises many other endpoints (sentiment analysis, summarization, geocoding, etc.) at the same $0.02 price point, but none have documented schemas either.","tags":[],"capabilities":["x402-payment","order-status","usdc-base","pay-per-request","json-response"],"categories":["commerce","data"],"synonyms":["order status API","x402 order lookup","micropayment API","Base USDC API","pay-per-call order status","lowpaymentfee"],"warnings":["No OpenAPI spec or response schema available — response format is unknown","Endpoint is hardcoded to order 137; unclear if other order IDs are supported via different paths","All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content","The broader platform advertises many endpoints but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/137/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/137/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 documented request/response schema, no examples, and the endpoint is hardcoded to a single order ID.
