Example prompt: Can you pull up the Saylor Innovations guide on agent sandboxing and untrusted code execution so I can understand the best practices for safely running AI-generated code?

## When to prefer this

Use this endpoint when an agent or developer needs authoritative reference content specifically about AI agent sandboxing and untrusted code execution practices. Prefer this over general web search when you want a curated, consistently structured knowledge base article rather than ad hoc search results.

## Known failure modes

- Article not found or endpoint returns empty body
- Payment not processed correctly, resulting in 402 response
- Malformed request type or method field returns validation error
- Service unavailable or timeout on the knowledge base backend
- License restrictions may limit redistribution of content

## How this service works

Agent Sandbox and Untrusted Code Execution. A sandbox profile and test suite that proves untrusted code cannot reach host credentials, unrelated files, internal services, unrestricted network destinations, excessive resources, or persistence beyond the job.

## Output

Returns a JSON object containing a unique article ID, title (t), category (c), and body text of the knowledge base article covering agent sandboxing and untrusted code execution. May also include a price and license field.
