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 on the Base network using USDC through the x402 payment protocol.\n\nThe specific endpoint `/api/v1/database/snapshots/2025-03` returns JSON and costs $0.02 per call (20,000 base units of USDC with 6 decimals). No API keys, rate limits, or upfront commitments are required; each request is paid individually via an X-PAYMENT header. The x402 challenge was successfully captured, confirming the endpoint is live.\n\nDocumentation is extremely sparse. The crawled docs, API, pricing, and README pages all rendered only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no description of what the database snapshot actually contains. The endpoint's purpose — what data the snapshot covers, its schema, or its intended audience — is entirely unknown from the available material.","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","monthly snapshot","data dump","database download","2025-03 snapshot","lowpaymentfee API"],"warnings":["No documentation available — all doc pages render only 'Connect wallet' with no content.","No OpenAPI or JSON schema describing request parameters or response format.","The contents and purpose of the 'database/snapshots/2025-03' resource are completely unknown from available material.","No examples of request body or response payload exist in crawled content."],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2025-03","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/2025-03","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base).
