2. Create a Sandbox & Execute Code

python

print(result.stdout)  # "420"

# Clean up
cell.kill()

typescript

import { Cell } from '@runsynapse/sdk';

const cell = await Cell.create({ apiKey: 'sk_live_...' });

await cell.run('x = 42');
const result = await cell.run('print(x * 10)');
console.log(result.stdout); // "420"

await cell.kill();
