It is part of a broader platform offering multiple API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, rate limits, or commitments required.\n\nPayment is handled via the x402 protocol on the Base network. The endpoint accepts USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) with a maximum amount of 20,000 base units, which equals $0.02 (USDC uses 6 decimals). The payment scheme is \"exact\" and settles to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a timeout of 300 seconds. The response MIME type is `application/json`.\n\nThe specific endpoint probed (`/api/v1/orders/12/status`) appears to be an order status lookup. However, the URL contains a hardcoded order ID (12), and there is no OpenAPI schema, documentation, or example responses available to clarify the request/response format or how to query arbitrary orders. The broader site lists many endpoints but the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no substantive documentation. This makes it difficult to assess the actual functionality or data quality of this specific endpoint.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","order-status","pay-per-request","no-api-key","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","pay-per-call API","USDC micropayment API","lowpaymentfee","Base network API"],"warnings":["No OpenAPI or schema documentation available for this endpoint","The URL contains a hardcoded order ID (/orders/12/status) — unclear how to query other orders","All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content","No example request or response bodies available to verify actual functionality","The broader platform lists many endpoints across categories but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/12/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/12/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 (returns a valid 402 x402 challenge) and pricing is clear at $0.02/request in USDC on Base.
