Pay-per-call loan data endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to a specific loan resource (ID 96) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum charge of 20,000 base units (0.02 USDC, i.e. $0.02 per request).
lowpaymentfee.com is a broader platform offering multiple pay-per-call API categories including data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payments flow through the x402 protocol on the Base L2 network.
The specific endpoint `/api/v1/loans/96` is labeled "Premium API Access" in the x402 challenge but lacks dedicated documentation explaining what loan data it returns or what POST body it expects. The broader site's docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. Without an OpenAPI schema, request/response examples, or descriptive docs, the exact functionality and data shape of this endpoint remain unclear.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and no documentation beyond a wallet-connect prompt. The purpose of the /loans/96 resource is unexplained, making this effectively a stub listing.
