What it does

This endpoint at lowpaymentfee.com returns a loan amortization schedule for a specific loan (loan ID 82) via a POST request. It is part of a broader platform offering pay-per-call APIs across data analytics, AI/ML, finance, and utility categories, all settled on the Base network using USDC through the x402 payment protocol.

The x402 challenge confirms the endpoint is live and accepts payments of up to $0.02 per request (20,000 base units of USDC with 6 decimals = $0.02). Payment is made in USDC on Base to the specified wallet address, with no API keys or rate limits required. The response MIME type is application/json.

Documentation is extremely sparse. The crawled docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the loan schedule endpoint accepts or returns. The endpoint path suggests it returns a payment schedule for a pre-existing loan resource (ID 82), but it is unclear whether the POST body configures the schedule parameters or whether other loan IDs are available. The platform advertises a uniform $0.02/request pricing model with no minimums, no commitments, and instant access.

Quality

0.30/ 1.00

The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages returned only a wallet-connect prompt. The specific purpose of this loan/82/schedule endpoint is only inferable from the URL path.

Warnings

  • —No API documentation available — docs, pricing, and API pages all render only a 'Connect wallet' prompt
  • —No OpenAPI or request/response schema provided; request body format and response structure are unknown
  • —Endpoint is hardcoded to loan ID 82; unclear if other loan IDs exist or if this is a demo resource
  • —The platform lists many API categories but this specific endpoint (loans) is not listed on the homepage
