It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request and settled on-chain via the x402 protocol using USDC on the Base network.\n\nThe specific endpoint `/api/v1/loans/1/schedule` accepts POST requests and returns JSON. Based on the URL structure, it likely computes or retrieves a payment schedule for loan ID 1, though no detailed input/output schema documentation was found in the crawl. The x402 challenge confirms the endpoint is live and requires a payment of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals.\n\nThe platform advertises no API keys, no rate limits, and instant access. All payments are handled via the x402 payment header — callers attach a signed USDC payment to each request. Documentation pages (/docs, /pricing, /api) returned only a \"Connect wallet\" prompt with no substantive content, so detailed request/response schemas are unavailable.","tags":[],"capabilities":["loan-amortization-schedule","pay-per-request","x402-payment","usdc-settlement","base-network","json-api","no-api-key"],"categories":["finance"],"synonyms":["loan schedule","amortization calculator","loan payment schedule","mortgage schedule","loan repayment plan","payment amortization","loan calculator API"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README all returned only 'Connect wallet' with no content.","Request and response schemas are entirely inferred from the URL path; no formal specification exists.","The endpoint path hardcodes loan ID 1 — it is unclear whether other loan IDs are supported or how loans are created.","Example request JSON is speculative; actual required fields are unknown."],"endpointUrl":"https://lowpaymentfee.com/api/v1/loans/1/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/1/schedule","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and confirms pricing and payment details, but there is no OpenAPI schema, no documented input/output format, and all documentation pages returned only a wallet-connect prompt.
