Secure Python & Bash execution API for AI agents
Run real Python 3.11 and shell commands inside an isolated workspace with memory and timeout limits, keeping untrusted code off your own machines.
List the libraries or system tools your agent needs and they are installed automatically and reproducibly for that run.
Send input data for processing and download everything the agent creates, including charts, logs, reports, and transformed datasets.
Use it as a single tool inside any agent framework with the agentsandbox-sdk, working client-side or server-side with minimal setup.
Build, test, and deploy production-grade voice AI agents over API
Configure speech recognition, an LLM reasoning layer and text-to-speech through one API instead of integrating several vendors separately.
The platform handles real-time audio streaming, interruption handling and call state so conversations feel natural and responsive.
Provision Vapi phone numbers or bring Twilio, Vonage or Telnyx, and support both inbound and outbound calling from the same agent.
Simulate calls before launch, then track transcripts, effectiveness metrics and compliance signals across every production call.
