ATP Token is an enterprise AI gateway and governance platform. A single project key gives an application access to 50+ large language models from multiple providers through OpenAI-, Anthropic- and Gemini-compatible interfaces. Every request is metered at the token level, converted into credits, and attributed to a project, workspace and organization, so AI consumption can be budgeted, capped, audited and reconciled. The platform adds multi-source routing with automatic fallback, model-level permission bound to each key, and an orchestration runtime that turns a validated workflow into a deployable production agent.
