It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/orders/130/status` accepts POST requests and requires an X-PAYMENT header containing a valid x402 payment proof. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.\n\nThe platform advertises no API keys, no rate limits, and instant access. However, documentation pages (/docs, /pricing, /api, /README) all resolve to a minimal \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The actual data returned by this order-status endpoint is unknown beyond the stated mime type of application/json.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","micropayment","pay-per-request"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 endpoint","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["Endpoint is hardcoded to order #130 — unclear if other order IDs are supported or if this is a demo","No OpenAPI spec or response schema available; response format is entirely unknown","All documentation pages (/docs, /pricing, /api, /README) return only a 'Connect wallet' prompt with no content","Platform lists many other endpoints (AI, finance, utils) but this listing covers only /api/v1/orders/130/status"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/130/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/130/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).
