It is one of many endpoints offered by the lowpaymentfee.com platform, which hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per call and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/database/snapshots/2024-06` is described only as \"Premium API Access\" with no further documentation on the request body schema or the structure of the returned data. The x402 challenge confirms the endpoint is live, accepts POST requests, and requires a payment of up to 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02. Payment is made via the x402 exact scheme with a 300-second timeout.\n\nDocumentation on the site is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response examples, and no description of what the 2024-06 database snapshot contains. Prospective users should be aware that the nature of the data returned is entirely unclear from available materials.","tags":[],"capabilities":["x402-payment","usdc-base","database-snapshot","pay-per-request","no-api-key"],"categories":["storage","data"],"synonyms":["database export","data snapshot","premium data access","lowpaymentfee","x402 data API","Base USDC API","micropayment data"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.","The contents and schema of the 2024-06 database snapshot are completely unknown from available materials.","No OpenAPI spec or output schema beyond the basic HTTP POST indicator.","The nature of the 'Premium API Access' data is unspecified — buyers cannot know what they are paying for."],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2024-06","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/2024-06","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is confirmed live via a valid x402 402 challenge, but there is zero documentation on what data the snapshot contains, no request/response schema, and no examples.
