What it does

This endpoint at lowpaymentfee.com returns a loan amortization schedule for a specific loan (loan ID 31 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 settled via the x402 protocol on the Base network using USDC.

The endpoint accepts POST requests and returns JSON. Payment is handled inline: callers attach an X-PAYMENT header containing a signed x402 payment. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The platform advertises a flat $0.02/request pricing across all endpoints, with no API keys, no rate limits, and no minimum commitments.

Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a wallet-connect prompt with no substantive content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The specific input parameters for the loan schedule endpoint (e.g., whether the loan ID is configurable, what fields the POST body expects) are unknown from the available material. The endpoint is confirmed live via a valid 402 challenge response.

Quality

0.30/ 1.00

The endpoint is confirmed live via a valid 402 challenge, but there is zero documentation: no OpenAPI spec, no request/response schema, no examples, and all doc pages render only a wallet-connect prompt. The specific purpose (loan schedule for a hardcoded loan ID 31) is narrow and unclear without further context.

Warnings

  • —No API documentation available — /docs, /pricing, /api, and /README pages are all empty beyond a wallet-connect prompt
  • —No OpenAPI or request/response schema provided; input parameters for the POST body are unknown
  • —The endpoint URL contains a hardcoded loan ID (31); it is unclear whether this is parameterizable
  • —The broader platform lists many diverse API categories (AI, analytics, finance, utilities) all at $0.02 — the actual functionality behind each is unverified
