E2B Toolkit
The E2B toolkit integrates E2B sandboxed code execution into Arcade, enabling LLMs to safely run code and generate visual output without local compute.
Capabilities
- Sandboxed code execution: Run arbitrary code in an isolated E2B sandbox and capture stdout/stderr output.
- Chart generation: Execute Python code using matplotlib and receive the resulting chart as a base64-encoded image, ready for embedding or display.
Secrets
E2B_API_KEY — An API key issued by E2B that authenticates requests to the E2B sandbox API. To obtain one, sign up at e2b.dev, then retrieve your API key from the E2B dashboard. No specific plan tier is documented as required for basic sandbox access, but usage may be subject to E2B's free-tier limits. Copy the key and register it as a secret in Arcade.
For configuring secrets in Arcade, see the Arcade secrets guide or manage them directly at https://api.arcade.dev/dashboard/auth/secrets.
