It is part of a broader platform offering various pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind the x402 payment protocol on the Base network using USDC.\n\nThe endpoint accepts POST requests and returns JSON. Payment is handled inline via the X-PAYMENT header using the x402 exact-payment scheme. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The platform advertises a flat $0.02/request pricing model across all its endpoints, with no API keys, no rate limits, and no minimum commitments.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is live (returns a proper 402 challenge), but without documentation it is unclear what request body fields are expected or what the response schedule format looks like. The loan ID (19) is hardcoded in the URL path, suggesting other loan IDs may also be available at similar paths.","tags":[],"capabilities":["loan-amortization-schedule","x402-payment","usdc-base-network","pay-per-request","json-api"],"categories":["finance"],"synonyms":["loan schedule","amortization calculator","loan payment schedule","loan repayment plan","mortgage schedule","payment breakdown","loan calculator API"],"warnings":["No documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content","No OpenAPI or request/response schema provided; request body format is unknown","Loan ID 19 is hardcoded in the URL; unclear if other loan IDs exist or how to discover them","No examples of request or response payloads available anywhere in crawled content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/loans/19/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/19/schedule","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge with clear pricing.
