Lago is an open-source billing platform for usage-based, subscription-based, and hybrid pricing models. It provides metering, billing, invoicing, entitlements, and related billing operations for SaaS, AI, fintech, and infrastructure companies.
Lago exposes a documented REST API with an OpenAPI spec and an MCP server/toolkit for AI agents; both rely on Lago API keys, and no public GraphQL API or first-party CLI surface was found.
