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/200/status` — is listed under the title \"Premium API Access\" and accepts POST requests. Payment is handled via the x402 protocol: callers receive a 402 challenge containing the payment details (asset, network, amount) and must attach an `X-PAYMENT` header with a valid payment proof. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02. No API keys or rate limits are advertised; access is gated purely by micropayment.\n\nDocumentation is extremely sparse. The landing page lists available API categories and pricing, but 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 documentation, and no usage examples. The endpoint is live (returns a valid 402 challenge), but the actual response format after successful payment is unknown.","tags":[],"capabilities":["x402-payment","order-status","usdc-micropayment","base-network","pay-per-call","no-api-key"],"categories":["commerce","infrastructure"],"synonyms":["order status API","order tracking","x402 endpoint","micropayment API","USDC pay-per-call","lowpaymentfee"],"warnings":["No documentation available — /docs, /pricing, /api, and /README all render only 'Connect wallet'","No OpenAPI or response schema provided; actual response format after payment is unknown","The endpoint path '/api/v1/orders/200/status' is not listed on the landing page among the advertised APIs — its purpose and behavior are unclear","Cannot verify what data is actually returned after successful payment"],"endpointUrl":"https://lowpaymentfee.com/api/v1/orders/200/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/200/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 exists and is operational.
