It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all priced at $0.02 per request and settled via the x402 protocol on the Base network using USDC.\n\nThe specific endpoint probed returns a live 402 challenge with `maxAmountRequired` of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made by including an `X-PAYMENT` header with a valid x402 payment proof. The response MIME type is `application/json`. No API keys, rate limits, or upfront commitments are required — callers simply pay per request.\n\nDocumentation on the site is extremely sparse: the docs, API, pricing, 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 example payloads available. The endpoint name (\"database snapshots 2025-10\") suggests it returns a point-in-time data export or snapshot, but the exact schema and contents are unknown. The platform lists many other endpoints across analytics, AI, finance, and utility categories, all at the same $0.02 price point.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","database-snapshot","json-response","per-request-pricing","no-api-key"],"categories":["data","storage"],"synonyms":["database export","data snapshot","October 2025 snapshot","lowpaymentfee API","x402 data endpoint","pay-per-request database","USDC API"],"warnings":["No OpenAPI or schema documentation available — request and response formats are entirely unknown","All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no content","The specific contents and structure of the 'database snapshots 2025-10' resource are undocumented","This endpoint is not listed on the provider's homepage among their advertised APIs"],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2025-10","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/2025-10","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 402 challenge with clear pricing ($0.02 USDC on Base).
