## Summary - Switches sandbox filesystem file uploads from `multipart/form-data` to `application/octet-stream` in both the JS and Python SDKs - Each file is now uploaded as raw binary with the path passed as a query parameter, matching the `application/octet-stream` content type in the envd API spec - Multi-file writes send one request per file sequentially ## Test plan - [ ] Run JS SDK filesystem write tests (`pnpm run test` in `packages/js-sdk`) - [ ] Run Python SDK filesystem write tests (`pytest` in `packages/python-sdk`) - [ ] Verify single file write, multi-file write, and various data types (string, bytes, streams) 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
What is E2B?
E2B is an open-source infrastructure that allows you to run AI-generated code in secure isolated sandboxes in the cloud. To start and control sandboxes, use our JavaScript SDK or Python SDK.
Run your first Sandbox
1. Install SDK
pip install e2b
2. Get your E2B API key
E2B_API_KEY=e2b_***
3. Start a sandbox and run commands
from e2b import Sandbox
with Sandbox.create() as sandbox:
result = sandbox.commands.run('echo "Hello from E2B!"')
print(result.stdout) # Hello from E2B!
4. Code execution with Code Interpreter
If you need run_code(), install the Code Interpreter SDK:
pip install e2b-code-interpreter
from e2b_code_interpreter import Sandbox
with Sandbox.create() as sandbox:
execution = sandbox.run_code("x = 1; x += 1; x")
print(execution.text) # outputs 2
