What it does

This endpoint at lowpaymentfee.com provides access to mortgage-related data at the path `/api/v1/mortgages/97`. It is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-request APIs spanning data analytics, AI/ML inference, finance, and utility services — all gated via the x402 payment protocol on the Base network using USDC.

The specific endpoint `/api/v1/mortgages/97` 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). This is consistent with the platform's uniform $0.02/request pricing displayed on its landing page. Payment is made inline via the X-PAYMENT header; no API keys, subscriptions, or rate limits are required.

Documentation beyond the landing page is extremely sparse — 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, and no description of what the mortgages resource actually returns. The endpoint path suggests it retrieves or processes data for a specific mortgage record (ID 97), but the exact input parameters and response shape are unknown. The platform appears live and the 402 challenge is well-formed, but the lack of documentation makes integration speculative.

Quality

0.25/ 1.00

The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI spec, no request/response schema, no documentation, and no indication of what the mortgages resource actually returns. This is effectively a stub listing.

Warnings

  • —No API documentation available — /docs, /pricing, /api, and /README all render only a wallet-connect prompt
  • —No OpenAPI or JSON schema for request or response bodies
  • —The specific resource '/api/v1/mortgages/97' is not listed on the landing page among advertised endpoints, so its purpose and data content are unknown
  • —No examples of request parameters or response payloads available
