What it does

This endpoint at lowpaymentfee.com provides access to mortgage-related data at the path `/api/v1/mortgages/63`. It is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call API endpoints 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/63` 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 settled on-chain on Base; no API keys, rate limits, or subscriptions are required.

Note that the endpoint path suggests it returns data for a specific mortgage record (ID 63). The platform's landing page does not list a mortgages category explicitly — the documented categories are Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure. No OpenAPI schema, detailed documentation, or example responses are available for this specific endpoint. The docs, pricing, and API pages on the site all render only a "Connect wallet" prompt with no further content, so the actual request/response schema 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 OpenAPI schema, no documentation beyond a wallet-connect prompt, no example request/response, and the mortgages category isn't even listed on the site's own landing page. The actual data returned is entirely unknown.

Warnings

  • No documentation available — docs, pricing, and API pages only show 'Connect wallet'
  • The /api/v1/mortgages/ path is not listed among the site's advertised API categories
  • No OpenAPI spec or response schema provided; request/response format is unknown
  • Cannot verify what data is actually returned for mortgage ID 63
