What it does

This x402-enabled endpoint at lowpaymentfee.com returns a loan amortization schedule for a specific loan (loan ID 97 in the URL path). It accepts POST requests and responds with JSON. Payment is settled on the Base network using USDC at $0.02 per request via the x402 exact-payment scheme.

The endpoint is part of a broader platform (lowpaymentfee.com) that advertises multiple API categories including data & analytics, AI/ML inference, finance & Web3, and infrastructure utilities — all priced at $0.02 per call. The platform emphasizes no API keys, no rate limits, and instant access. However, the specific endpoint listed here (/api/v1/loans/97/schedule) is not explicitly documented on the site's landing page among the advertised APIs, so its exact input schema and response format are unknown.

The x402 challenge is live and returns a valid 402 response with USDC (contract 0x8335…2913 on Base) as the accepted asset. The maxAmountRequired is 20000 base units, which at 6 decimals equals $0.02. No OpenAPI spec, detailed docs, or example responses were found in the crawl. The docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.

Quality

0.30/ 1.00

The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI spec, no documentation of request/response schemas, no examples, and the specific /loans/97/schedule path is not listed among the site's advertised APIs. The docs pages returned no content. This is effectively a stub listing.

Warnings

  • No OpenAPI or schema documentation available for this endpoint
  • The /api/v1/loans/97/schedule path is not listed among the site's advertised APIs — it may be an unlisted or test endpoint
  • All documentation pages (docs, API, pricing, README) returned only a 'Connect wallet' prompt with no substantive content
  • Request body schema is unknown — unclear what parameters the POST endpoint expects
  • The loan ID (97) is hardcoded in the URL; it is unclear whether other loan IDs are supported
