It is part of a broader suite of pay-per-request APIs hosted on lowpaymentfee.com, all priced at $0.02 per call and settled via x402 protocol using USDC on the Base network.\n\nThe x402 challenge confirms the endpoint is live and accepts POST requests. Payment is made in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base) with a max amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). No API keys or rate limits are advertised — access is gated solely by the per-request micropayment. The response MIME type is `application/json`.\n\nThe exact schema and contents of the database snapshot are not documented in the crawled material. The provider's site lists many endpoints across data/analytics, AI/ML, finance/Web3, and infrastructure categories, but specific documentation pages returned only a \"Connect wallet\" prompt with no further detail. As a result, the precise fields returned by this snapshot endpoint remain unknown.","tags":[],"capabilities":["database-snapshot","x402-payment","usdc-base","pay-per-request","json-response"],"categories":["storage","data"],"synonyms":["database export","data snapshot","historical data dump","December 2024 snapshot","database backup API","data archive"],"warnings":["No documentation available — all doc/pricing/README pages return only a 'Connect wallet' prompt","Response schema and request body format are completely undocumented","Exact contents of the 'database snapshot' are unknown — could be anything","Provider site is very generic with many endpoint categories but no substantive docs for any of them"],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2024-12","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/database/snapshots/2024-12","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base).
