# pkgsafe.adrwent.fyi

> pkgsafe.adrwent.fyi is a paid API for AI agents from pkgsafe.adrwent.fyi, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Checks npm or PyPI packages for safety signals and returns a verdict (ok, caution, avoid, unknown) with evidence including malware flags, maintainer changes, install scripts, and vulnerability advisories.

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 pkgsafe-adrwent-fyi-c49abfb0
```

Example prompt: Before I install it, can you check if the npm package 'lodash' is safe — look for any malware flags, maintainer changes, or suspicious install scripts?

## When to prefer this

Use this endpoint when an agent needs to vet an npm or PyPI package before installation or dependency updates, especially in automated CI/CD pipelines, dependency review workflows, or when a user asks whether a specific open-source library is safe. Prefer this over generic vulnerability scanners when you need a fast, per-package signal that includes supply-chain indicators like maintainer changes, install script additions, and publisher shifts — not just CVE lookups.

## Known failure modes

- Unknown package name returns verdict 'unknown' with no signals
- Unsupported ecosystem (not npm or pypi) results in validation error
- Package version not found may fall back to latest or return unknown
- Network or registry lookup failures may return unknown verdict
- Very new or obscure packages may have limited signal data

## How this service works

Call before installing or updating an npm or PyPI dependency. Returns a verdict (ok, caution, avoid, unknown) plus evidence signals: install script added, maintainer or publisher change, very recent publish, build provenance dropped, known malware and vulnerability advisories. A clean result is not a guarantee of safety.

## Output

Returns a safety verdict (ok, caution, avoid, or unknown) for the specified package, along with evidence signals such as: whether an install script was added, whether the maintainer or publisher changed, how recently the package was published, whether build provenance was dropped, and any known malware or vulnerability advisories. A clean verdict does not guarantee safety.
