satsgate is an innovative service designed to facilitate the integration of Lightning paywalls for AI agents, APIs, and web applications, enabling users to charge satoshis (sats) effortlessly—without the complexities of developing a payment infrastructure.

Key Features:

• L402 Paywall Management: Seamlessly implement a Lightning paywall by utilizing two straightforward API calls: /v1/paywall/challenge (to return a 402 status) and /v1/paywall/verify.
• Prepaid Credits: Manage financial transactions with prepaid credit plans, ensuring predictable cost structures where 1 credit equates to 1 successful verification.
• Usage Reporting and Forecasting: Gain insights through detailed usage reports, ledger entries, daily summaries, and forecasts that guide purchasing decisions, ensuring efficient budget management.
• Lightweight Design: satsgate functions as a cash management system, serving as a turnstile for your agent without placing additional load on LLMs in real-time processing.
