It is part of a broader platform offering various pay-per-request APIs spanning data analytics, AI/ML inference, finance, and utility services — all gated behind x402 micropayments settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/backups/2024-11/download` accepts POST requests and returns application/json content. Payment is handled via the x402 protocol: callers must include an X-PAYMENT header with a valid payment proof. The maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. No API keys, rate limits, or subscriptions are needed — just a per-call USDC micropayment.\n\nThe platform advertises a uniform $0.02/request pricing model across all its endpoints. Documentation pages exist but appear to require wallet connection to view, so detailed schema information for request/response payloads is not available from the crawl. The endpoint is live and returning a proper 402 challenge.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","file-download","backup-retrieval","pay-per-request"],"categories":["storage","data"],"synonyms":["backup download","data export","file retrieval","x402 API","micropayment API","USDC payment endpoint","Base chain API"],"warnings":["No request or response schema available — payload format is undocumented","Documentation pages require wallet connection and could not be crawled","The purpose of 'backups/2024-11' is unclear — it may be sample/demo data rather than a production backup service","This endpoint is not listed on the provider's homepage among their advertised APIs"],"endpointUrl":"https://lowpaymentfee.com/api/v1/backups/2024-11/download","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/backups/2024-11/download","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live with a valid 402 challenge and clear pricing ($0.02 USDC on Base).
