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" service at the path `/api/v1/paypal/payments/16`. It is part of a broader platform offering dozens of pay-per-call API endpoints across categories like data analytics, AI/ML inference, finance, crypto, and utility services — all gated by the x402 payment protocol on the Base network.
The specific endpoint accepts POST requests and is priced at 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, meaning the caller includes an X-PAYMENT header with a signed payment for each call. No API keys, rate limits, or upfront commitments are required — access is instant once payment is attached.
The platform's landing page lists a uniform $0.02/request pricing model across all endpoints. Documentation pages (/docs, /pricing, /README) appear to require a wallet connection and returned minimal content during crawl, so the actual request/response schemas for this particular PayPal payments endpoint are unknown. The endpoint's purpose — whether it initiates PayPal payments, retrieves payment data, or performs some other PayPal-related operation — cannot be confirmed from the available material.
