What it does

This x402-enabled endpoint at lowpaymentfee.com returns a loan amortization schedule for a specific loan (loan ID 89 in the URL path). It accepts POST requests and responds with JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at $0.02 per request via the x402 exact payment scheme.

The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. The specific endpoint cataloged here falls under the finance category and produces a loan repayment schedule. However, the crawled documentation pages are essentially empty (showing only a "Connect wallet" prompt), so there is no detailed schema documentation for request parameters or response format. The loan ID (89) is hard-coded in the URL path, which may indicate either a demo/sample resource or that callers are expected to vary the path segment for different loans.

Because no OpenAPI spec, request body schema, or example responses were found in the crawl, the exact fields accepted in the POST body and the structure of the returned schedule are unknown. Agents should expect a JSON response containing typical amortization data (payment periods, principal, interest, balance) but this is inferred, not confirmed.

Quality

0.35/ 1.00

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the loan ID is hard-coded in the path with no explanation. Effectively a stub listing.

Warnings

  • —No OpenAPI or schema documentation available — request body and response structure are unknown.
  • —Documentation pages (/docs, /api, /pricing, /README) all render only a 'Connect wallet' prompt with no useful content.
  • —The loan ID 89 is hard-coded in the endpoint path; it is unclear how to request schedules for other loans.
  • —The endpoint is listed as 'Premium API Access' with no further description from the provider.
