What it does

This endpoint at lowpaymentfee.com provides access to loan data (resource ID 36) via the x402 payment protocol. It accepts HTTP POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).

The provider lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. This specific endpoint (/api/v1/loans/36) is labeled "Premium API Access" and appears to serve loan-related financial data, though the exact response schema is not documented in the crawled material.

The endpoint is live and returns a valid x402 challenge (HTTP 402) when called without payment. Documentation beyond the landing page is extremely thin — 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 example request/response, and no description of what fields the loan endpoint returns. Agents should expect a JSON response but will need to discover the schema experimentally.

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI spec, no documented request/response schema, and no meaningful documentation beyond a landing page. The specific purpose of /api/v1/loans/36 is unclear — 'Premium API Access' is generic. Score reflects minimal usable information.

Warnings

  • No OpenAPI or schema documentation available — response format is unknown
  • All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no technical content
  • The endpoint path '/api/v1/loans/36' suggests a specific loan resource but no description of what data it returns is provided
  • The label 'Premium API Access' is generic and does not describe the endpoint's actual function
