What it does

This endpoint at lowpaymentfee.com provides access to mortgage-related data at the path `/api/v1/mortgages/92`. 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, crypto, and utility services — all gated via the x402 payment protocol on the Base network using USDC.

The specific endpoint `/api/v1/mortgages/92` 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 site's advertised flat pricing of $0.02 per request across all endpoints. No API keys are required; payment is handled inline via the X-PAYMENT header.

Documentation on the site is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. The endpoint path suggests it returns data about a specific mortgage record (ID 92), but no schema, field definitions, or example responses are available. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to know what data is actually returned.

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no request/response schema, and no description of what mortgage data is actually returned. The docs pages are empty. This is effectively a stub listing.

  • —The path '/api/v1/mortgages/92' is not listed on the site's homepage among available APIs, raising questions about whether this is a production endpoint or a test/demo resource
