It is one of many endpoints offered by the lowpaymentfee.com platform, which hosts a variety of data, analytics, AI/ML, finance, and utility APIs — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific resource `/api/v1/backups/2024-02/download` accepts POST requests and returns `application/json` content. Payment is made by attaching an `X-PAYMENT` header conforming to x402 version 1 with the \"exact\" scheme. The max amount required is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a timeout of 300 seconds.\n\nThe broader lowpaymentfee.com platform advertises no API keys, no rate limits, and instant access. Documentation pages (/docs, /pricing, /README) appear to require a wallet connection and contain no substantive content in the crawl. There is no OpenAPI schema, no detailed documentation about the backup format or contents, and no example responses available, so the actual payload structure is unknown.","tags":[],"capabilities":["x402-payment","usdc-base","backup-download","micropayment","post-endpoint"],"categories":["storage","data"],"synonyms":["backup download","data export","February 2024 backup","lowpaymentfee","x402 backup API","file download API","paid data download"],"warnings":["No OpenAPI or JSON schema available for request or response bodies","Documentation pages (/docs, /pricing, /README) are wallet-gated and returned no useful content","The actual contents and format of the 'February 2024 backup' are completely undocumented","No example responses available — the payload structure is unknown"],"endpointUrl":"https://lowpaymentfee.com/api/v1/backups/2024-02/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/2024-02/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 402 challenge, confirming pricing and payment details.
