Riza Code Interpreter API
Riza provides a secure, sandboxed code execution API optimized for AI agents. Agents can execute arbitrary Python, JavaScript, Ruby, and PHP code in isolated microVMs without the security risks of running code on your servers. Sub-second cold starts, no infrastructure to manage.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
⚡ Reliability
Best When
Your agent generates code and needs to execute it safely without standing up your own sandboxing infrastructure. Purpose-built for AI-generated code.
Avoid When
You need persistent execution environments, network access to private resources, or GPU-accelerated code.
Use Cases
- • Agent-generated Python/JS code execution in isolated environments
- • Data analysis and transformation by AI agents (pandas, numpy, etc.)
- • Math and computation tasks delegated to agents
- • Automated testing code execution in secure sandboxes
- • AI coding assistants that verify generated code actually runs
Not For
- • Long-running processes (execution time limit applies)
- • Code requiring network access to internal services (sandboxed network)
- • Heavy compute workloads (not optimized for ML training)
- • Production workloads needing persistent state between executions
Interface
Authentication
Simple API key authentication via Authorization: Bearer header. One key per project. No scoped permissions — key has full account access.
Pricing
Very competitive pricing for agent use cases. Free tier is sufficient for development and low-volume production.

Known Gotchas
- ⚠ Execution timeout: default 30 seconds, configurable up to 300 seconds
- ⚠ No network access by default — code cannot make HTTP calls to external services
- ⚠ Package availability: pre-installed packages only; no pip install at runtime
- ⚠ Memory limit: 512MB default — large datasets may hit this
- ⚠ Output size limit: 5MB — large print outputs get truncated
- ⚠ No persistent filesystem between executions — stateless by design
