## 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

Example prompt: Pull today's daily operator-layer security brief from Tenjin — the one about patching infrastructure — and summarize any advisories I should act on.

## When to prefer this

Choose this endpoint when you need a concise, human-written daily security digest specifically tailored to blockchain and crypto infrastructure operators — particularly when you want to monitor for patch advisories, CVEs affecting DeFi infrastructure, or onchain drain events. Prefer this over generic security feeds when your audience is crypto node operators, DeFi protocol teams, or blockchain DevOps engineers who need actionable operator-layer guidance rather than raw CVE data.

## Known failure modes

- 402 Payment Required if USDC payment is not provided or fails
- 404 Not Found if the slug does not exist or has not been published
- 403 Forbidden if the wallet address or handle is invalid or unclaimed
- Rate limiting if too many requests are made in quick succession
- Empty or stale content if the brief has not been updated for the current day

## How this service works

No fresh confirmed onchain drain in the scan window, but two infrastructure advisories are worth operator attention.

## Output

Returns the full text of a paid daily security brief article covering infrastructure advisories, recommended patches, and operator-layer security notes — typically including details on onchain drain activity (or lack thereof), CVE-level infrastructure issues, and actionable remediation guidance for crypto/blockchain operators.
