What it does

This endpoint at lowpaymentfee.com returns a loan amortization schedule for a specific loan (loan ID 14 in the URL path). It is part of a broader platform offering various 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 responds with a 402 Payment Required challenge, indicating it accepts x402 payments. The price per request is $0.02 USDC (maxAmountRequired of 20,000 base units with 6 decimals). Payment is made to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base. The endpoint accepts POST requests and returns application/json.

Documentation is extremely sparse — the crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what parameters the POST body should contain or what the schedule response looks like. The loan schedule functionality is inferred solely from the URL path structure. The platform advertises no API keys, no rate limits, and instant access across all its endpoints.

Quality

0.25/ 1.00

The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC per request), but there is no documentation, no OpenAPI schema, no request/response examples, and the loan schedule functionality is inferred only from the URL path. The docs pages are empty beyond a wallet-connect prompt.

Warnings

  • —No API documentation available — all doc pages return only a 'Connect wallet' prompt
  • —No OpenAPI or request/response schema provided; request body format is unknown
  • —The endpoint is hardcoded to loan ID 14; it is unclear whether other loan IDs are supported or how loans are created
  • —No examples of successful responses exist in the crawled material
