What it does

This endpoint at lowpaymentfee.com provides access to mortgage-related data at the path `/api/v1/mortgages/72`. 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/72` 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 stated flat pricing of $0.02 per request across all endpoints. Payment is made inline via the X-PAYMENT header; no API keys or accounts are required.

The endpoint's exact response schema and accepted input fields are not documented in the crawled material. The site's docs, pricing, and API pages all rendered only a "Connect wallet" prompt with no further content. The mortgage-specific path (`/mortgages/72`) suggests it may return data for a particular mortgage product or record identified by ID 72, but this is speculative. Without documentation or example responses, the precise data returned is unknown.

Quality

0.35/ 1.00

The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation, no input/output schema, and no example responses for this specific mortgage endpoint. The docs pages returned only wallet-connect prompts. The listing is effectively a stub with confirmed liveness and pricing.

Warnings

  • —No documentation available for /api/v1/mortgages/72 — input fields and response schema are unknown
  • —All doc/pricing/API pages on the site render only a 'Connect wallet' prompt with no usable content
  • —The purpose of the '/mortgages/72' path (whether it's a specific record, a category, or a template) is unclear
