Useautumn

A billing API that replaces in-house usage tracking, gating, and asynchronous billing logic for AI applications. It solves the complexity of AI billing, which is harder than seat-based pricing, by decoupling billing logic from code. The product targets developers and engineering teams at AI startups who need to manage payments, balances, and entitlements across pricing changes. It is positioned as a single API and database purpose-built for real-time monetization, allowing configuration via dashboard or CLI.
