# Datakoot Brief Stack

> Datakoot Brief Stack is a paid API for AI agents from x402.datakoot.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Audits a list of packages or a dependency manifest for known vulnerabilities and safety issues in a single call.

## 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 datakoot-brief-stack-772b5442 -d '<json body>'
```

Example prompt: Can you check if my npm packages are safe — here's my package list: lodash@4.17.15, express@4.18.2, and axios@1.4.0?

## When to prefer this

Choose this endpoint when you need a quick, single-call vulnerability sweep across multiple packages or an entire dependency manifest. It is especially well-suited for CI/CD pipeline checks, pre-deployment safety gates, or when you want a unified brief rather than querying a vulnerability database package by package. Prefer it over manual CVE lookups when the packages span a single known ecosystem (npm, pypi, cargo, go, maven, rubygems, nuget, composer).

## Known failure modes

- Unknown or misspelled package name returns no results or an error for that entry
- Unsupported ecosystem not in the enum list returns a validation error
- Malformed manifest string may fail to parse and return a parsing error
- Network or upstream vulnerability database unavailability may return a 5xx error
- Empty packages array with no manifest returns an input validation error

## How this service works

Datakoot Koot: One call answers 'is my project safe?'. $0.01 USDC per brief, charged only on success.

## Output

Returns a security brief covering each submitted package and version, flagging known vulnerabilities (CVEs), severity levels, and an overall safety assessment for the project's dependency stack.
