The endpoint accepts POST requests and returns JSON data. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals).\n\nlowpaymentfee.com hosts a variety of pay-per-request APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced uniformly at $0.02 per call. This specific endpoint (`/api/v1/database/snapshots/2023-12`) appears to serve a historical database snapshot, though the exact schema of the returned data is not documented in the available crawl material. No API keys or rate limits are advertised; access is gated solely by the x402 payment header.\n\nThe endpoint is live and returns a valid 402 challenge. However, documentation is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further technical detail. The request body schema and response format are unknown beyond the stated MIME type of application/json.","tags":[],"capabilities":["x402-payment","base-network","usdc-settlement","database-snapshot","json-response","no-api-key","pay-per-request"],"categories":["data","storage"],"synonyms":["database export","historical snapshot","data dump","2023 december snapshot","database download","archived data"],"warnings":["No request or response schema documented — callers cannot know what to send or what they will receive","All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no technical content","The nature and contents of the 'database snapshot 2023-12' are completely unspecified","Provider site appears to be a generic multi-API storefront; unclear if endpoints return real data"],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2023-12","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/2023-12","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live with a valid 402 challenge and clear pricing, but there is no documentation of request/response schemas, no OpenAPI spec, and all doc pages render only 'Connect wallet'.
