## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-linux-permissions-resolver-2ea10084
```

Example prompt: Can you pull up the Linux permissions guide from Saylor Innovations — I need to understand how chmod octal codes work and how to fix a permission denied error on my server?

## When to prefer this

Choose this endpoint when an AI agent needs a pre-written, structured reference article on Linux permissions to deliver to a user, rather than generating an answer from model knowledge. Useful for agents that want citable, curated reference content with a license attached, or when consistency and authoritative sourcing matter. At $0.01 per call it is cost-effective for on-demand lookups within automated workflows.

## Known failure modes

- Malformed request method or type — 400 Bad Request
- Service unavailable — 503 or 500 error with no article body returned
- Empty or null body field if article content is missing
