What it does

This endpoint at lowpaymentfee.com returns a loan amortization schedule for a specific loan (loan ID 95 in the URL path). It is part of a broader platform offering various pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind the x402 payment protocol on the Base network using USDC.

The endpoint accepts POST requests and returns JSON. Each call costs $0.02 in USDC (20,000 base units with 6 decimals) settled on-chain via the x402 "exact" payment scheme to a specified wallet address. There are no API keys, no rate limits, and no subscription commitments — payment is handled entirely through the X-PAYMENT header per the x402 protocol.

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 spec, no request/response schema documentation, and no examples of what input the POST body expects or what the schedule output looks like. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it difficult to use without experimentation.

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 challenge with clear pricing, but there is zero documentation on request format, response schema, or what loan ID 95 represents. No OpenAPI spec, no examples, and all doc pages are empty. This is effectively a stub listing.

Warnings

  • —No API documentation available — /docs, /api, /pricing, and /README all return only a wallet connect prompt
  • —No request body schema or response schema documented; callers must guess the POST payload
  • —The endpoint is hardcoded to loan ID 95 — unclear if other loan IDs are supported or how they are created
  • —No OpenAPI or ai-plugin manifest found
