It uses the x402 payment protocol, requiring a per-request micropayment of $0.02 in USDC on the Base network. The endpoint accepts POST requests and returns JSON data.\n\nThe provider lowpaymentfee.com hosts a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required. This specific endpoint (`/api/v1/database/snapshots/2024-11`) appears to deliver a historical database snapshot, though the exact schema of the returned data is not documented in the available crawl material.\n\nPayment is settled on-chain via USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on the Base L2 network. The x402 challenge specifies a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals) with a timeout of 300 seconds. No OpenAPI spec or detailed response schema was found.","tags":[],"capabilities":["database-snapshot","x402-payment","base-network","usdc-settlement","per-request-pricing","json-response"],"categories":["data","storage"],"synonyms":["database export","historical snapshot","data dump","November 2024 snapshot","lowpaymentfee database","paid data access","x402 data endpoint"],"warnings":["No OpenAPI spec or response schema available — the actual data returned by this endpoint is undocumented","Documentation pages (/docs, /pricing, /README) returned no meaningful content","The nature and contents of the 'database snapshot' are entirely unspecified"],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2024-11","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/2024-11","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 confirmed) and pricing is clear, but there is no documentation of request parameters, response schema, or what data the snapshot actually contains.
