Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 tenjin-security-briefs-escaped-localhost-daily-brief-37e6c8a1
```

Example prompt: Pull the Tenjin daily security brief on escaped-localhost and AI-gateway vulnerabilities — the one covering CISA's latest SharePoint RCE and FortiSandbox command-injection KEV entries.

## When to prefer this

Choose this endpoint when you need structured, up-to-date daily security intelligence specifically covering AI-agent attack surfaces, localhost-escape vulnerabilities, CISA KEV additions, and MCP/AI-gateway advisories — as opposed to general threat feeds or broad cybersecurity news. Ideal for agents that automate daily security triage or vulnerability digest workflows.

## Known failure modes

- Payment not completed (x402 payment required, 0.1 USDC) — returns 402 Payment Required
- Invalid or non-existent slug — article not found
- Handle does not match a known creator — 404 or empty response
- Article not yet published for current date — returns latest available or 404
- Network/upstream timeout from tenjin.blog

## How this service works

CISA added exploited SharePoint RCE and two FortiSandbox command-injection entries with July 19 due dates, while fresh MCP and AI-gateway advisories put localhost defaults, discovery fetches, and object-storage endpoints under review.

## Output

Returns the full text of the paid daily security brief article, including CISA KEV additions (e.g. SharePoint RCE CVEs, FortiSandbox command-injection entries with due dates), MCP and AI-gateway advisory summaries, analysis of localhost-default risks, discovery-fetch concerns, and object-storage endpoint exposure findings.
