It is one of many endpoints offered by the lowpaymentfee.com platform, which hosts a variety of data, analytics, AI/ML, finance, and utility APIs — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/database/snapshots/2023-08` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers must include an `X-PAYMENT` header with a valid payment proof. The cost per call is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. No API keys, rate limits, or upfront commitments are required — each request is individually paid.\n\nDocumentation beyond the landing page is sparse. The docs, API, pricing, and README pages all resolve to a minimal \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The exact contents and structure of the 2023-08 database snapshot are not described anywhere in the crawled material, so consumers will need to experiment or contact the provider to understand the data format.","tags":[],"capabilities":["x402-payment","usdc-base","database-snapshot","json-response","per-request-pricing","no-api-key","post-endpoint"],"categories":["data","storage"],"synonyms":["database snapshot API","historical data snapshot","2023-08 snapshot","x402 data endpoint","Base USDC API","lowpaymentfee","micropayment data access"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no technical content.","The contents and schema of the 2023-08 database snapshot are completely undocumented.","No OpenAPI specification or example request/response payloads are provided.","The broader lowpaymentfee.com platform lists many endpoints but none have detailed docs; quality of all endpoints is uncertain."],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2023-08","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/2023-08","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no request/response schema, and no description of what the database snapshot actually contains.
