## 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-guide-library-troubleshooting-cname-records-0ed6cb9c
```

Example prompt: Can you pull up the CNAME troubleshooting guide from the Saylor Innovations knowledge base so I can figure out why my custom domain isn't resolving correctly?

## When to prefer this

Use this endpoint when an agent or user needs authoritative step-by-step guidance on diagnosing and fixing CNAME DNS record issues, especially when looking for structured knowledge-base content rather than a live DNS lookup or real-time record check. Prefer this over general web search when you want a curated, paywall-gated technical article with a stable, citable ID and license.

## Known failure modes

- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Article not found at the specified path — returns 404 Not Found
- Service unavailable or upstream error — returns 500 or 503
- Malformed request method — only GET is supported, other methods may return 405

## How this service works

Troubleshooting CNAME Records. How to verify and debug a CNAME record: looking it up with nslookup or dig/MXToolbox, and resolving the common failures — unpropagated changes, mistyped Label/Target values, trailing-dot errors, and the A-vs-CNAME conflict on the same hostname.

## Output

A JSON object containing a unique article ID, title (t), category (c), and a body field with the full text of the CNAME troubleshooting knowledge-base article, plus optional price and license metadata.
