It is part of a broader suite of x402-enabled APIs offered by the same provider, spanning data analytics, AI/ML inference, finance, and utility categories — all priced at $0.02 per request with no API keys, rate limits, or commitments required.\n\nThe endpoint is live and responds with a standard x402 payment challenge. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with the \"exact\" scheme. The maximum amount required is 20,000 base units, which at 6 decimals equals $0.02. The HTTP method is POST, and the response MIME type is application/json. A 300-second payment timeout is configured.\n\nDocumentation beyond the landing page is essentially empty — 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 explanation of what the backup file contains or what parameters (if any) the POST body accepts. The endpoint path suggests a static monthly backup archive, but the actual contents and format are unknown.","tags":[],"capabilities":["x402-payment","base-network","usdc-settlement","file-download","backup-archive","pay-per-request"],"categories":["storage","data"],"synonyms":["backup download","data export","archive download","x402 backup","paid file download","monthly backup","lowpaymentfee"],"warnings":["No documentation available — /docs, /pricing, /api, and /README all return only a wallet-connect prompt with no content.","No OpenAPI or schema describing request parameters or response format for this endpoint.","Unknown backup contents — the endpoint path implies a July 2024 backup but there is no description of what data is included.","The provider hosts many endpoints but none have documented schemas or examples."],"endpointUrl":"https://lowpaymentfee.com/api/v1/backups/2024-07/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/2024-07/download","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base).
