The provider operates a broad suite of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint probed — `/api/v1/orders/50/status` — is labeled \"Premium API Access\" in the x402 challenge. It accepts POST requests and returns JSON. Payment is handled via the x402 exact-payment scheme: the caller includes an X-PAYMENT header with a USDC payment of up to 20,000 base units (i.e., $0.02 given USDC's 6 decimals) to the specified payTo address on Base. No API keys or rate limits are advertised; access is gated purely by micropayment.\n\nDocumentation is extremely thin. The /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema beyond the x402 challenge's outputSchema stub, and no explanation of what fields the order status response contains. The provider's landing page confirms the $0.02 pricing and lists many other endpoints, but provides no detailed documentation for any of them.","tags":[],"capabilities":["x402-payment","usdc-base","order-status","pay-per-request","no-api-key","json-response"],"categories":["commerce","infrastructure"],"synonyms":["order tracking","order status check","x402 API","micropayment API","Base USDC API","pay-per-call","lowpaymentfee"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README all return only a 'Connect wallet' prompt with no content.","No OpenAPI or request/response schema provided; response format is unknown.","The endpoint path '/api/v1/orders/50/status' has a hardcoded order ID (50); it is unclear whether this generalizes to other order IDs or what 'orders' refers to in this context.","Provider lists many endpoints on its landing page but none have documented behavior."],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/50/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/50/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), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the specific purpose of this 'orders/50/status' endpoint is unexplained.
