Call sandbox_create with a template such as node, python, react, or nextjs, optionally adding packages and environment variables. Then use sandbox_execute with the sandbox_id, your code, language, and a timeout to run it and capture output.

Browse available templates with template_list or template_get, then call template_deploy with the template name, a deployment name, and any required variables like database URLs. You can also publish your own apps using app_store_publish_app.

Flow Nexus offers seven templates: node, python, react, nextjs, vanilla, base, and claude-code. Each provides a preconfigured environment, and you can extend them with install_packages, environment variables, and startup scripts.

Check your balance with check_balance and buy credits via create_payment_link, which returns a Stripe payment URL with a $10 minimum. You can enable auto-refill at a set threshold and earn credits through challenges, referrals, and template sales.

Executions time out when the timeout parameter is too low or the code is inefficient. Increase the timeout value in sandbox_execute, optimize the code, and check sandbox_logs for errors such as failed package installs or memory limits.

List challenges with challenges_list filtered by difficulty and category, then submit solutions via challenge_submit. Rewards range from 10-25 credits for beginner challenges up to 600-1000 for master level, plus achievement bonuses.
