Database snapshot access (2023-10) via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides access to a database snapshot dated 2023-10 via the x402 payment protocol. 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.
The 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.
Because 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.

Quality
