What it does

This endpoint at lowpaymentfee.com returns a loan amortization schedule for a specific loan (loan ID 39 in the URL path). It is part of a broader platform offering pay-per-call APIs across data analytics, AI/ML, finance, and utility categories, all settled via the x402 protocol on the Base network using USDC.

The endpoint is live and returns a 402 challenge requesting payment of up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per request. Payment is made via the x402 "exact" scheme to the specified wallet address. The response MIME type is application/json. The endpoint accepts POST requests and is marked as discoverable.

Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The loan schedule endpoint itself is not listed on the homepage (which advertises analytics, AI, finance, and utility endpoints), so its exact input parameters and output format are unknown. The platform advertises a flat $0.02 per request, no API keys, no rate limits, and instant access.
