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.\n\nThe specific endpoint `/api/v1/mortgages/75` 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). The platform's landing page confirms a flat $0.02/request pricing model across all endpoints, with no API keys, no rate limits, and no minimum commitments required.\n\nDocumentation is extremely sparse — the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what the mortgages endpoint actually returns. The endpoint name suggests mortgage financial data (possibly a specific mortgage record identified by ID 75), but the exact payload structure and fields are unknown. The endpoint is confirmed live via a valid 402 challenge.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","mortgage-data","json-api","post-method"],"categories":["finance"],"synonyms":["mortgage API","mortgage data","home loan API","lowpaymentfee","x402 mortgage","USDC pay-per-call","Base network API","mortgage rates","mortgage calculator"],"warnings":["No documentation available — docs, pricing, and API pages all show only 'Connect wallet' with no content.","No OpenAPI or request/response schema provided; the exact data returned by /api/v1/mortgages/75 is unknown.","The endpoint path suggests a specific mortgage record (ID 75) but it is unclear whether this is a fixed resource or parameterized.","The mortgages endpoint is not listed on the provider's own landing page among available APIs, raising questions about its status."],"endpointUrl":"https://lowpaymentfee.com/api/v1/mortgages/75","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/mortgages/75","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02/request in USDC on Base).
