What it does

This endpoint at lowpaymentfee.com provides a loan amortization schedule via a POST request to `/api/v1/loans/25/schedule`. It is part of a broader platform offering data, analytics, AI, finance, and utility APIs, all gated behind the x402 payment protocol. Each call costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required.

The x402 challenge confirms the endpoint is live and accepts exact-scheme payments in USDC (contract `0x8335…2913` on Base) with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The response MIME type is `application/json`. The endpoint is discoverable and uses HTTP POST.

Documentation beyond the landing page is extremely thin — the /docs, /pricing, /api, 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 example payloads available. The specific behavior of the `/loans/25/schedule` path (whether `25` is a loan ID, term length, or other parameter) is not documented. Consumers should expect to experiment or contact the provider for integration details.

Quality

0.30/ 1.00

The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the semantics of the URL path (e.g., what '25' represents) are undocumented. This is effectively a stub listing.

Warnings

  • —No API documentation available — /docs, /pricing, /api, and /README all return only a 'Connect wallet' prompt
  • —No OpenAPI or JSON schema for request or response bodies
  • —The meaning of '/loans/25/schedule' (what '25' represents) is not documented
  • —No example requests or responses available from the provider
