It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs, all payable per-request via the x402 protocol on the Base network using USDC.\n\nThe specific endpoint `/api/v1/database/snapshots/2026-05` accepts POST requests and returns JSON. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). This is consistent with the platform's uniform $0.02/request pricing displayed on its landing page. No API keys are required; payment is handled entirely through the x402 payment header.\n\nDocumentation is extremely sparse — the docs, pricing, API, 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 \"database snapshot\" actually contains or what fields the POST body should include. The endpoint is confirmed live (returns a proper 402 challenge), but without documentation it is unclear what data is returned or what input parameters are expected.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","database-snapshot","per-request-pricing","no-api-key","json-response"],"categories":["data","storage"],"synonyms":["database snapshot API","data export","lowpaymentfee","x402 data endpoint","USDC pay-per-request API","Base network API","database dump"],"warnings":["No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content.","No OpenAPI or input/output schema provided; request body format and response structure are unknown.","The nature of the 'database snapshot' for 2026-05 is completely undocumented — unclear what data it contains.","The date '2026-05' is in the future relative to typical data, which is unusual and unexplained."],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2026-05","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/2026-05","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02/request in USDC on Base).
