What it does

This x402-enabled endpoint at lowpaymentfee.com returns a loan amortization schedule for a specific loan (loan ID 80 in the URL path). It is part of a broader platform offering various pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind x402 micropayments on the Base network using USDC.

The endpoint accepts POST requests and returns JSON. Each call costs a maximum of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). Payment is made via the x402 protocol's X-PAYMENT header, settling to a specified wallet address on Base. There are no API keys, no rate limits, and no subscription commitments — callers pay per request.

Documentation beyond the landing page is extremely thin: the /docs, /api, /pricing, 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 for this specific loans/schedule endpoint. The endpoint is confirmed live (returns a proper 402 challenge), but the exact request body format and response structure for the loan schedule are unknown.

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 challenge, confirming it exists and is gated at $0.02 USDC on Base. However, there is no documentation for request/response schemas, no OpenAPI spec, and the crawled docs/pricing/README pages are all empty beyond a wallet-connect prompt. The specific loan schedule endpoint's input parameters and output format are entirely unknown.

Warnings

  • —No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no technical content
  • —No OpenAPI or schema definition found for this endpoint
  • —Request body format and response structure for the loan schedule endpoint are undocumented
  • —The endpoint is hardcoded to loan ID 80; it is unclear whether other loan IDs are supported or how loans are created
  • —The broader platform lists many API categories but none appear to include a loans/schedule endpoint on the landing page, raising questions about completeness
