## 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 aiskills402-watchdog-alert-review-skill-file-69163803

Example prompt: Buy me the Watchdog Alert Review skill from AISkills402 — the one about silent and noisy alarms — so I can use it to evaluate my monitoring setup.

## When to prefer this

Choose this endpoint when an AI agent needs to acquire the specific 'Watchdog Alert Review: Silent and Noisy Alarms' SKILL.md instruction file to improve its ability to evaluate monitoring alerts. It is ideal for one-time skill purchases where permanent ownership and free re-downloads are valuable. Prefer this over generic document retrieval when the agent operates in a DevOps or observability context and needs a vetted, structured skill file delivered via x402 micropayment on Base.

## Known failure modes

- Invalid or expired payment header — returns 401 or 402
- Network error contacting Base blockchain for settlement verification
- Skill file temporarily unavailable — server error 500
- Malformed request headers — returns 400 Bad Request
