Pay-per-call premium API endpoint on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at `/api/endpoint-95` is part of the lowpaymentfee.com platform, which offers a collection of pay-per-request APIs spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities. All endpoints use the x402 payment protocol, settling in USDC on the Base network. The platform advertises a flat $0.02 per request with no API keys, no rate limits, and instant access.
The specific endpoint `/api/endpoint-95` is labeled "Premium API Access" but its exact functionality is not documented beyond that generic title. The x402 challenge confirms it is live, accepts POST requests, and requires payment of up to 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. The response MIME type is application/json.
Note that while the platform's homepage lists many categorized endpoints (analytics, AI, finance, utilities), this particular endpoint path (`/api/endpoint-95`) does not appear among them, and no documentation describes what it returns. The docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. Treat this as a stub listing until more documentation becomes available.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no OpenAPI schema, no example responses, and the endpoint path does not match any of the listed APIs on the homepage. The generic title 'Premium API Access' gives no indication of what the endpoint actually does. This is effectively a stub.
