The endpoint is live and returns a 402 challenge requiring a USDC payment on the Base network. The cost per request is $0.02 (20,000 base units of USDC with 6 decimals). Payment is made inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required.\n\nThe provider hosts a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request and settled in USDC on Base. This specific endpoint (`/api/v1/database/snapshots/2023-10`) is not listed on the provider's landing page among the featured APIs, so its exact data contents are unclear. The endpoint accepts POST requests and returns application/json. No request body schema or response schema documentation was found in the crawl.\n\nBecause the docs, pricing, and README pages all rendered only a \"Connect wallet\" prompt with no additional content, there is very limited documentation available for this endpoint. The nature of the \"database snapshot\" — what data it contains, what fields are returned, and what POST body parameters it accepts — is not documented in any crawled material.","tags":[],"capabilities":["x402-payment","usdc-base","database-snapshot","pay-per-request","no-api-key","json-response"],"categories":["data","storage"],"synonyms":["database snapshot API","historical data snapshot","2023-10 snapshot","x402 data endpoint","pay-per-call database","lowpaymentfee database"],"warnings":["No request body schema documented — unclear what parameters the POST endpoint accepts","No response schema or example response available","This specific endpoint (/api/v1/database/snapshots/2023-10) is not listed on the provider's landing page, raising questions about its status","All documentation pages (docs, pricing, README, api) returned only 'Connect wallet' with no content","The nature and contents of the 'database snapshot' are completely undocumented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2023-10","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/2023-10","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation on what the snapshot contains, no request/response schema, and the endpoint is not listed among the provider's featured APIs.
