x402-gated loan data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a specific loan resource (loan ID 78) via the x402 payment protocol. It is part of a broader platform that offers a variety of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all gated behind x402 micropayments on the Base network using USDC.
The specific endpoint `/api/v1/loans/78` is labeled "Premium API Access" by the provider. The x402 challenge confirms it is live, accepting POST requests, and requires a maximum payment of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 USD (USDC uses 6 decimals). Payment is made via the x402 "exact" scheme to the provider's wallet. No API keys or rate limits are advertised; access is granted purely through per-call payment.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the loan data resource actually returns. The endpoint path suggests it retrieves or operates on a loan record, but the exact fields, input parameters, and response format are unknown. Agents should be aware that the actual utility of this endpoint cannot be verified from available documentation alone.

Quality
