## 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-agent-tool-security-preflight-guide-8a518452
```

Example prompt: Pull up the agent tool security preflight guide from Saylor Innovations — I need the best practices article on what checks an AI agent should run before calling an external HTTP tool.

## When to prefer this

Choose this endpoint when an AI agent or developer needs structured, on-demand security guidance specifically about preflight checks for agent-callable HTTP tools. It is particularly useful during agent pipeline design, security audits, or developer onboarding when a curated knowledge-base article is preferred over a general web search.

## Known failure modes

- Invalid or missing 'input.type' (must be 'http') returns a validation error
- Invalid 'input.method' enum value returns a 400-level error
- Service unavailable or network timeout returns no article body
- Payment not processed (x402 flow failure) results in access denial
