It is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-request 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.\n\nThe specific endpoint `/api/v1/mortgages/73` 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 stated flat pricing of $0.02 per request across all endpoints. No API keys are required; payment is handled inline via the X-PAYMENT header. The platform advertises no rate limits and instant access.\n\nDocumentation is extremely sparse — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no substantive content. The endpoint path suggests it returns data about a specific mortgage (ID 73), but there is no schema documentation, example request/response, or description of what fields are returned. The mortgage endpoint is not listed on the homepage's catalog of available APIs, which raises questions about whether it is a production endpoint or a test/demo resource.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","mortgage-data","per-call-pricing","no-api-key","json-response"],"categories":["finance"],"synonyms":["mortgage API","mortgage data","home loan API","real estate finance","x402 mortgage","lowpaymentfee","USDC pay-per-call","Base network API"],"warnings":["No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content.","The /api/v1/mortgages/73 endpoint is not listed in the provider's homepage API catalog, raising questions about its status.","No request body schema or response schema is documented anywhere.","The nature of the data returned (what mortgage fields, data source, freshness) is entirely unknown."],"endpointUrl":"https://lowpaymentfee.com/api/v1/mortgages/73","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/73","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base).
