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 PayPal payments API accessible via the x402 payment protocol. The URL path (`/api/v1/paypal/payments/15`) suggests it handles PayPal payment operations, though the exact request/response schema is not documented in the available crawl material.
The endpoint is live and returns a valid x402 challenge. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum amount of 20,000 base units, which equals $0.02 (USDC uses 6 decimals). The provider advertises a flat $0.02 per request across all their APIs, with no API keys, no rate limits, and instant access. The x402 scheme is "exact" with a 300-second timeout.
The provider hosts a broader catalog of APIs spanning data/analytics, AI/ML, finance/Web3, and infrastructure utilities — all at the same $0.02 price point. However, documentation is extremely sparse: the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no examples for this specific PayPal payments endpoint. The exact functionality (e.g., whether it initiates a PayPal payment, retrieves payment details for ID 15, or something else) cannot be confirmed from available material.
