Pay-per-call PayPal payments endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides a "Premium API Access" resource at the path `/api/v1/paypal/payments/85`. It is part of a broader platform offering dozens of pay-per-call API endpoints across categories like data analytics, AI/ML inference, finance, and infrastructure utilities — all gated by the x402 payment protocol on the Base network.
The specific endpoint accepts POST requests and is priced at a maximum of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is made via the x402 "exact" scheme, settling directly to the provider's wallet on Base. No API keys or accounts are required; access is granted immediately upon valid payment. The platform advertises no rate limits and no minimum commitments.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no explanation of what the `/paypal/payments/85` endpoint actually returns or what input it expects. The endpoint name suggests PayPal payment processing functionality, but this cannot be confirmed from available materials. Prospective users should proceed with caution given the lack of documentation.
