# Vulnerability Intelligence – Batch Package Vulnerability Check

> Vulnerability Intelligence – Batch Package Vulnerability Check is a paid API for AI agents from vuln-intel.x402tookit.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-21).

Check up to 10 package versions across ecosystems (npm, PyPI, Go, Maven, etc.) for known vulnerabilities in a single call, returning advisory counts, verdicts, and affected package details.

## Facts

- Endpoint: GET https://vuln-intel.x402tookit.com/vuln-batch?utm_source=zero.xyz
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-21
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/vulnerability-intelligence-batch-package-vulnerability-check-19079be2
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_4g_adlDKu2SLZ_vFqwL5U

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 vulnerability-intelligence-batch-package-vulnerability-check-19079be2
```

Example prompt: Can you check these packages for known vulnerabilities all at once: npm:lodash@4.17.15, PyPI:requests@2.19.0, and npm:express@4.17.1?

## When to prefer this

Use this endpoint when you need to check multiple packages in a single request across one or more ecosystems (npm, PyPI, Go, Maven). It is more efficient than calling the single-package endpoint repeatedly. Prefer it when auditing a dependency list, running a CI/CD security gate, or vetting a batch of third-party libraries before adoption. If you need deeper detail on a single advisory by CVE/GHSA ID, use the single-advisory endpoint instead.

## Known failure modes

- More than 10 packages submitted — only up to 10 are supported per call
- Malformed package identifier format (missing ecosystem prefix or version) — package may appear in notChecked list
- Unknown or unsupported ecosystem — package returned as unchecked
- Stale or unavailable upstream vulnerability database — degraded flag set to true
- Network timeout or upstream data source unavailability — may return partial results

## How this service works

Check up to 10 package versions at once for known vulnerabilities: list as npm:lodash@4.17.15,PyPI:requests@2.19.0.

## Output

Returns a verdict (e.g. vulnerable/safe), the number of vulnerable packages, advisory counts per package, CVE/GHSA IDs per package, the data source and timestamp, a summary string, a list of any packages that could not be checked, and a disclaimer. Optionally includes a degraded flag if the data source was partially unavailable.
