Pay-per-call PayPal payments endpoint on Base via x402, $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides a "Premium API Access" resource at the path `/api/v1/paypal/payments/65`. It is part of a broader platform offering various pay-per-request APIs (data analytics, AI/ML, finance, infrastructure) all settled via the x402 protocol on the Base network using USDC.
The endpoint accepts POST requests and charges 20,000 base units of USDC (0.02 USD) per call, paid via the x402 payment header. No API keys or rate limits are advertised — access is gated purely by micropayment. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, using the USDC contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`.
The specific functionality behind this particular path (`/paypal/payments/65`) is not documented beyond the generic "Premium API Access" label. The platform's landing page lists many endpoint categories but does not include this exact path among them, and the docs/pricing/README pages all render only a "Connect wallet" prompt with no further documentation. As a result, the actual response payload and use case for this endpoint remain unclear.
