What it does

This endpoint at lowpaymentfee.com returns a loan amortization schedule for a specific loan (loan ID 22 in the URL path). It is part of a broader platform offering various pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — 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 on Base. 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, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request body documentation, and no example responses available. The specific loan schedule endpoint 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/request pricing model with no API keys, no rate limits, and instant access.

The endpoint is live and returns a valid x402 402 challenge, but there is no documentation, no OpenAPI schema, no request/response examples, and the specific endpoint (/loans/22/schedule) is not even listed on the provider's homepage. The docs pages are empty. Input parameters and output format are entirely unknown.

Warnings

  • —No OpenAPI or request/response schema provided; input parameters for the loan schedule endpoint are unknown
  • —This specific endpoint (/api/v1/loans/22/schedule) is not listed among the provider's advertised APIs on the homepage
  • —Loan ID 22 is hardcoded in the URL path — unclear if other loan IDs are supported or how loans are created
