It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all gated via the x402 payment protocol on the Base network using USDC.\n\nThe specific endpoint `/api/v1/database/snapshots/2024-08` accepts POST requests and returns JSON. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0.02 USD per request, since USDC uses 6 decimals). Payment is settled on-chain to a Base address, with a timeout of 300 seconds. No API keys or rate limits are advertised; access is granted purely through per-call micropayment.\n\nDocumentation is extremely sparse. The landing page lists many endpoints across several categories, but the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no description of what the database snapshot actually contains or what fields are returned. The endpoint is live (402 challenge confirmed), but without documentation it is difficult to know what data to expect or what POST body to send.","tags":[],"capabilities":["database-snapshot","x402-payment","usdc-micropayment","base-network","json-response","per-request-billing"],"categories":["data","storage"],"synonyms":["database export","data snapshot","August 2024 snapshot","historical data dump","database download","data archive"],"warnings":["No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'","No OpenAPI or JSON schema describing request body or response format","Unknown contents of the 'database snapshot' — no field descriptions or sample data","The endpoint name suggests a static historical dataset but this is unverified"],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2024-08","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/2024-08","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).
