What it does

This endpoint at lowpaymentfee.com returns a loan amortization schedule for a specific loan (loan ID 77 in the URL path). 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 settled via the x402 protocol on the Base network using USDC.

The endpoint is live and responds with a 402 Payment Required challenge, indicating it accepts x402 exact-scheme payments of up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per request. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base. The endpoint accepts POST requests and returns application/json. No API key or account registration is required — access is gated purely by micropayment.

Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all rendered only a "Connect wallet" prompt with no further content. The specific request body schema for the loan schedule endpoint is not documented, and no example responses are available. The loan ID (77) is hard-coded in the URL path, suggesting either a demo/sample loan or that callers would substitute their own loan ID. Without documentation it is unclear what input parameters are expected or what fields the schedule response contains.

Quality

0.30/ 1.00

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC per request on Base), but there is no documentation, no request/response schema, no examples, and the loan ID is hard-coded with no explanation. Effectively a stub listing.

Warnings

  • —No API documentation available — docs, pricing, and README pages all render only a wallet-connect prompt with no content
  • —Request body schema for the loan schedule endpoint is completely unknown
  • —Loan ID 77 is hard-coded in the endpoint path; unclear if this is a demo or if other IDs are supported
  • —No example responses available to verify output format
