It is part of a broader platform offering pay-per-request APIs across data analytics, AI/ML, finance, and utility categories, all settled on the Base network using USDC via the x402 protocol.\n\nThe x402 challenge confirms the endpoint is live and accepts POST requests. The price is 20,000 base units of USDC (0x8335…2913 on Base), which at 6 decimals equals $0.02 per request. No API keys or rate limits are advertised — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The endpoint returns application/json.\n\nDocumentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The specific loan schedule endpoint (/api/v1/loans/23/schedule) is not listed on the homepage's API catalog, so its exact input parameters and response format are unknown. The listing description \"Premium API Access\" is generic and does not describe the endpoint's actual functionality. Users should expect to experiment with POST body parameters to discover the correct request format.","tags":[],"capabilities":["loan-amortization-schedule","x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key","json-response"],"categories":["finance"],"synonyms":["loan schedule","amortization calculator","loan payment schedule","mortgage schedule","loan repayment plan","payment breakdown","debt amortization"],"warnings":["No OpenAPI or schema documentation available — request and response formats are unknown","The /api/v1/loans/23/schedule endpoint is not listed on the provider's homepage API catalog","All documentation pages (/docs, /api, /pricing, /README) returned only a 'Connect wallet' prompt with no content","The loan ID '23' is hardcoded in the URL; it is unclear whether other loan IDs are supported or how loans are created"],"endpointUrl":"https://lowpaymentfee.com/api/v1/loans/23/schedule","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/loans/23/schedule","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no request/response schema, and no examples.
