The endpoint accepts USDC on the Base network with a maximum cost of $0.02 per call (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — access is granted purely through per-request micropayment using the x402 protocol.\n\nThe broader lowpaymentfee.com platform advertises a suite of APIs spanning data & analytics, AI & machine learning (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with the same x402 payment model on Base. However, the specific endpoint being listed here is `/api/v1/orders/93/status`, which appears to be an order status lookup.\n\nDocumentation on the site is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available. The endpoint is confirmed live (returns a proper 402 challenge), but the actual response format and the meaning of the order status payload are unknown.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","micropayment","per-request-billing","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","micropayment API","Base USDC payment","pay-per-request API","lowpaymentfee"],"warnings":["No OpenAPI or schema documentation available — response format is completely unknown","Docs, API, pricing, and README pages all render only 'Connect wallet' with no content","Endpoint path is hardcoded to order ID 93; unclear if this is a demo or a real resource","No information about what the order status response contains"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/93/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/93/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 402 challenge, confirming it works.
