It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs, all payable per-request via the x402 protocol on the Base network using USDC.\n\nThe specific endpoint `/api/v1/database/snapshots/2026-02` accepts POST requests and returns JSON. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). This matches the platform's advertised flat pricing of $0.02 per request across all endpoints. No API keys are required; payment is handled entirely through the x402 payment header.\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 schema, no request/response examples, and no description of what the \"database snapshot\" actually contains or what fields the POST body should include. The endpoint is confirmed live (returns a proper 402 challenge), but without documentation it is unclear what data is returned or what input parameters are expected.","tags":[],"capabilities":["x402-payment","usdc-base","per-request-pricing","database-snapshot","json-response","post-method"],"categories":["data","storage"],"synonyms":["database snapshot API","data export","x402 data endpoint","Base USDC API","pay-per-request data","lowpaymentfee","database download","snapshot access"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.","No OpenAPI or schema describing request parameters or response format.","The nature of the 'database snapshot' (what data, what schema, what coverage) is completely undocumented.","The snapshot is labeled '2026-02' which is a future date — unclear if this is placeholder or forward-looking data."],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2026-02","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/2026-02","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no OpenAPI schema, no request/response examples, and no description of what the database snapshot contains.
