The specific resource at `/api/v1/database/snapshots/2025-02` accepts POST requests and returns JSON data. Payment is $0.02 per request (20,000 base units of USDC with 6 decimals), matching the uniform pricing across the platform.\n\nlowpaymentfee.com advertises categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities. All endpoints share the same pricing model: no API keys, no rate limits, no minimums, and instant access. The x402 challenge was successfully captured, confirming the endpoint is live and accepting payment via the \"exact\" scheme to a specified wallet address on Base.\n\nDocumentation is extremely sparse. The docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no description of what the \"database snapshots\" resource actually contains. The endpoint's purpose and data format must be inferred entirely from its URL path, which suggests it returns some kind of periodic data snapshot for February 2025, but the actual content and schema are unknown.","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","February 2025 snapshot","lowpaymentfee API","x402 data endpoint"],"warnings":["No documentation available — docs, API, pricing, and README pages all return only 'Connect wallet' with no content.","No OpenAPI or schema definition; request body and response format are completely unknown.","The nature and contents of the 'database snapshot' are undocumented — buyer has no way to evaluate the data before paying.","No robots.txt or agents.txt present."],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2025-02","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/2025-02","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02/request in USDC on Base).
