Database snapshot for March 2025, payable per-request via x402 on Base with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a database snapshot dated 2025-03 via a POST request. It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all priced at $0.02 per request and settled on the Base network using USDC through the x402 payment protocol.
The specific endpoint `/api/v1/database/snapshots/2025-03` returns JSON and costs $0.02 per call (20,000 base units of USDC with 6 decimals). No API keys, rate limits, or upfront commitments are required; each request is paid individually via an X-PAYMENT header. The x402 challenge was successfully captured, confirming the endpoint is live.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all rendered only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no description of what the database snapshot actually contains. The endpoint's purpose — what data the snapshot covers, its schema, or its intended audience — is entirely unknown from the available material.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no description of what the database snapshot actually contains. This is effectively a stub listing.
