What it does

This endpoint at lowpaymentfee.com returns a loan amortization schedule for a given loan (identified by ID in the URL path). It is part of a broader platform offering dozens of 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 specific endpoint `/api/v1/loans/10/schedule` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The platform's landing page confirms uniform $0.02/request pricing across all endpoints, with no API keys, no rate limits, and no minimum commitments required.

Documentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no usage examples available from the crawl. The loan schedule endpoint is not listed on the homepage's catalog (which focuses on analytics, AI, finance, and utility categories), so its exact request parameters and response shape are unknown. The endpoint is confirmed live via a valid 402 challenge.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, and no documentation beyond a wallet-connect prompt. The loan schedule endpoint isn't even listed on the site's own catalog, making its parameters entirely unknown.

Warnings

  • —No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content.
  • —The /api/v1/loans/10/schedule endpoint is not listed on the provider's homepage catalog, so its existence and parameters are unverified beyond the 402 challenge.
  • —No request body schema or response schema is documented anywhere; integration requires trial and error.
  • —No OpenAPI spec or ai-plugin manifest found.
