It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all settled via the x402 protocol using USDC on the Base network.\n\nThe endpoint accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335… on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is handled inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required. The payment timeout is 300 seconds.\n\nDocumentation beyond the landing page is extremely sparse: the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The specific input parameters for the loan schedule endpoint (e.g., loan amount, term, interest rate) and the shape of the response are unknown from the crawled material. The endpoint is confirmed live (returns a proper 402 challenge).","tags":[],"capabilities":["loan-amortization-schedule","x402-payment","usdc-settlement","base-network","pay-per-request","json-api"],"categories":["finance"],"synonyms":["loan schedule","amortization calculator","loan payment schedule","mortgage schedule","loan repayment plan","payment breakdown","debt schedule"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README all return only a wallet-connect prompt","No OpenAPI or JSON schema for request or response bodies","The endpoint path includes a hardcoded loan ID (/loans/2/schedule); it is unclear whether this is parameterizable or what loan ID 2 represents","Input parameters for the loan schedule calculation are unknown"],"endpointUrl":"https://lowpaymentfee.com/api/v1/loans/2/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/2/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 challenge with clear pricing, but there is no documentation, no OpenAPI spec, no request/response schema, and no examples.
