It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities. All endpoints on the platform use the x402 protocol for payment, settling in USDC on the Base network.\n\nThe specific endpoint at `/api/v1/database/snapshots/2024-02` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0.02 USD per request, since USDC uses 6 decimals). The provider emphasizes a no-API-key, no-rate-limit model: callers simply attach an x402 payment header and receive the response. The payment timeout is 300 seconds.\n\nDocumentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the 2024-02 snapshot actually contains. The endpoint is live (returns a proper 402 challenge), but without documentation it is unclear what data fields or structure the snapshot provides.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","database-snapshot","json-response","pay-per-request","no-api-key"],"categories":["data","storage"],"synonyms":["database export","data snapshot","historical data","2024-02 snapshot","lowpaymentfee","x402 data api","USDC pay-per-call"],"warnings":["No documentation available — /docs, /api, /pricing, and /README pages all return only a wallet-connect prompt with no content.","No OpenAPI or output schema describing the snapshot's data fields or structure.","The description 'Premium API Access' is generic and does not explain what data the 2024-02 snapshot contains.","Cannot verify what data is actually returned without making a paid request."],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2024-02","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/2024-02","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 challenge, but there is no OpenAPI schema, no documentation, no request/response examples, and no description of what the snapshot data actually contains.
