It is part of a broader platform offering pay-per-call APIs across data analytics, AI/ML, finance, and utility categories, all settled via the x402 protocol on the Base network using USDC.\n\nThe endpoint is live and returns a 402 challenge requesting payment of up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per request. Payment is made via the x402 \"exact\" scheme to the specified wallet address. The response MIME type is application/json. The endpoint accepts POST requests and is marked as discoverable.\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 further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The loan schedule endpoint itself is not listed on the homepage (which advertises analytics, AI, finance, and utility endpoints), so its exact input parameters and output format are unknown. The platform advertises a flat $0.02 per request, no API keys, no rate limits, and instant access.","tags":[],"capabilities":["loan-amortization-schedule","x402-payment","usdc-settlement","base-network","pay-per-request","json-response"],"categories":["finance"],"synonyms":["loan schedule","amortization calculator","loan payment schedule","loan repayment plan","mortgage schedule","x402 finance API","lowpaymentfee"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content","No OpenAPI or schema definition found for this endpoint","The /api/v1/loans/39/schedule path is not listed among the provider's advertised endpoints on the homepage","Request body format and response schema are completely unknown — integration requires guesswork or direct experimentation","Loan ID 39 is hardcoded in the URL; unclear if other loan IDs are supported or how loans are created"],"endpointUrl":"https://lowpaymentfee.com/api/v1/loans/39/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/39/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, but there is no documentation, no OpenAPI spec, no request/response schema, and no examples.
