It is part of a broader platform that offers a variety of API categories — data & analytics, AI & machine learning, finance & Web3, 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/156/status` accepts POST requests and returns JSON. Payment is handled via the x402 protocol: the endpoint returns a 402 challenge with payment details, and the caller includes an `X-PAYMENT` header to authorize a USDC micropayment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). Payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, with a timeout of 300 seconds. No API keys or rate limits are advertised; access is instant upon payment.\n\nThe platform's landing page lists many other endpoints across analytics, AI (sentiment analysis, summarization, classification, embeddings), finance (price feeds, exchange rates, token quotes, gas estimates), and infrastructure (geocoding, validation, conversion, generation), all at the same $0.02 price point. However, the crawled documentation pages (`/docs`, `/api`, `/pricing`, `/README`) returned only a \"Connect wallet\" prompt with no further technical detail, so the actual response schema and behavior of this specific order-status endpoint are not documented.","tags":[],"capabilities":["x402-payment","usdc-micropayment","base-network","order-status","json-response","no-api-key","pay-per-request"],"categories":["commerce","infrastructure"],"synonyms":["order status API","x402 order lookup","micropayment API","USDC pay-per-call","Base network API","lowpaymentfee"],"warnings":["Documentation pages (/docs, /api, /pricing, /README) all returned only 'Connect wallet' with no usable content.","The endpoint path is hardcoded to order #156 — unclear if other order IDs are supported or if this is a demo.","No response schema or example response is available; actual output format is unknown.","No OpenAPI spec or AI plugin manifest found."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/156/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/156/status","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but the specific order-status endpoint is narrow (hardcoded order #156), documentation pages are empty (only 'Connect wallet'), and there is no response schema, example payloads, or explanation of what the order status response contains.
