What it does

This endpoint at lowpaymentfee.com returns a loan amortization schedule for a specific loan (loan ID 83 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 a specified wallet address. The response MIME type is application/json. The endpoint accepts POST requests and is marked as discoverable.

Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no examples of what fields the loan schedule endpoint expects or returns. The loan ID (83) is hardcoded in the URL path, and it is unclear whether other loan IDs are available or how loans are created. The platform advertises $0.02 per request, no API keys, no rate limits, and instant access across all its endpoints.

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The loan ID is hardcoded with no explanation. This is effectively a stub listing.

Warnings

  • —No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
  • —No OpenAPI or request/response schema provided
  • —Loan ID 83 is hardcoded in the endpoint path; unclear how to access other loans or create new ones
  • —No examples of expected request body or response format
