level 4: agent integration

E2B is a cloud platform providing secure computers with real-world tools for AI agents. It allows developers to build and deploy agentic workflows by giving AI access to a sandboxed environment. You can use E2B to create AI agents that can perform tasks requiring internet access, file manipulation, and other real-world interactions.
