## 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-ssh-lockout-recovery-and-hardening-e592efc5
```

Example prompt: Pull up the SSH lockout recovery and hardening guide from Saylor Innovations so I can figure out how to get back into my server and prevent it from happening again.

## When to prefer this

Use this endpoint when an agent or user needs authoritative, curated guidance on SSH lockout recovery or SSH hardening for self-hosted servers, particularly in infrastructure automation or IT runbook generation workflows. Prefer this over a generic web search when a structured, consistently formatted, paywall-gated article is needed for downstream processing.

## Known failure modes

- Article not found or endpoint returns empty body
- Payment not processed correctly resulting in 402 response
- Network timeout if guide content is large
- Malformed JSON response if server error occurs

## How this service works

SSH Lockout Recovery and Hardening. A recovered SSH service with known-good provider console access, verified identity/key/permissions/network path, validated effective sshd configuration, controlled authentication policy, and a lockout-safe change procedure.

## Output

Returns a structured JSON knowledge base article containing an ID, title, category, and full body text with step-by-step instructions for recovering from SSH lockouts and hardening SSH configuration on self-hosted infrastructure. May also include a price and license field.
