Database snapshot access (2023-11) via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint provides access to a database snapshot dated November 2023, served by lowpaymentfee.com. It uses the x402 payment protocol, accepting USDC payments on the Base network at $0.02 per request. No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid payment proof to receive the data.
The hosting site (lowpaymentfee.com) offers a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced uniformly at $0.02 per request. This specific endpoint (`/api/v1/database/snapshots/2023-11`) is not prominently listed on the landing page among the featured APIs, so its exact response schema and data contents are unclear. The endpoint is confirmed live (returns a proper 402 x402 challenge) and accepts POST requests.
Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of what the 2023-11 snapshot contains.
