It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all gated behind per-request x402 micropayments settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/backups/2024-10/download` accepts POST requests and returns an `application/json` response. Payment is $0.02 per request (20,000 base units of USDC with 6 decimals). The platform advertises no API keys, no rate limits, and instant access — callers simply attach an x402 payment header to each request. The x402 challenge is live and returns a standard 402 response with payment parameters including the payTo address and USDC asset contract on Base.\n\nDocumentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the backup data actually contains. The endpoint's purpose (what data is being backed up, its format, its size) is entirely unclear from available materials.","tags":[],"capabilities":["x402-payment","usdc-base","file-download","backup-data","per-request-billing","no-api-key"],"categories":["storage","data"],"synonyms":["backup download","data export","x402 API","micropayment API","USDC payment endpoint","Base network API","pay-per-request download"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content","No OpenAPI or schema describing request parameters or response format","The nature and contents of the 'backup' data are completely undocumented","No request or response examples available anywhere in crawled material"],"endpointUrl":"https://lowpaymentfee.com/api/v1/backups/2024-10/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/2024-10/download","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base).
