It is one of many endpoints offered by the lowpaymentfee.com platform, which provides a broad catalog 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/181/status` is described generically as \"Premium API Access\" in the x402 challenge. The platform advertises no API keys, no rate limits, and instant access. Payment is made per-call via the x402 `exact` scheme: the caller attaches an X-PAYMENT header with a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the payTo address on Base. The response MIME type is `application/json`.\n\nDocumentation on the site 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 example payloads available. The endpoint is confirmed live (returns HTTP 402 with a valid x402 challenge), but without documentation it is unclear what fields the order status response contains or what input the POST body expects.","tags":[],"capabilities":["x402-payment","usdc-base","per-call-micropayment","order-status","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 order lookup","lowpaymentfee API","micropayment API","pay-per-call order status","Base USDC API"],"warnings":["No API documentation available — all doc/pricing/README pages render only 'Connect wallet'","No request body schema or response schema provided; callers must guess at the expected input and output","Endpoint is hardcoded to order ID 181; it is unclear whether other order IDs are queryable at different paths","The generic 'Premium API Access' description gives no insight into what data is actually returned"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/181/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/181/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'.
