Pay-per-request PayPal payments endpoint via x402 on Base, settled in USDC at $0.02/call.
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/30` suggests it handles PayPal payment operations (the trailing `30` may indicate a specific payment configuration or tier). Each request costs $0.02 in USDC on the Base network, with no API keys, rate limits, or upfront commitments required.
The endpoint accepts POST requests and returns JSON responses. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header containing a signed USDC payment of up to 20,000 base units ($0.02) to the provider's wallet on Base. The x402 challenge confirms the endpoint is live and operational with a 300-second payment timeout window.
The broader lowpaymentfee.com platform advertises a suite of APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/crypto data feeds, and infrastructure utilities — all at the same $0.02 per-request price point. However, the specific functionality of this PayPal payments endpoint is not well-documented; the crawled docs, pricing, and API pages all returned only a wallet-connect prompt with no additional detail. The exact request body schema and response format are unknown.
