# Ambolt Package Vulnerability Scanner

> Ambolt Package Vulnerability Scanner is a paid API for AI agents from api.ambolt.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-10).

Checks an npm or PyPI package for known security vulnerabilities, deprecation status, and latest version info sourced from OSV.dev

## Facts

- Endpoint: GET https://api.ambolt.dev/v1/package-vulnerabilities?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ambolt-package-vulnerability-scanner-963d761e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_pQWeZ5xGKBCiYKdrQaqc-

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 ambolt-package-vulnerability-scanner-963d761e
```

Example prompt: Check if lodash version 4.17.20 on npm has any known security vulnerabilities and tell me what severity they are and which version fixes them.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call programmatic vulnerability check for a specific npm or PyPI package without setting up a full security scanning pipeline. It's ideal for AI agents doing pre-install checks, CI gatekeeping, or auditing individual dependencies on demand. Prefer it over running local tools (e.g. npm audit) when operating in a serverless or agent context without local package install access. The OSV.dev data source covers a broad range of CVEs and GitHub Security Advisories.

## Known failure modes

- Invalid package name format — returns error if name doesn't match allowed pattern
- Package not found in the specified ecosystem — may return empty results or error
- Version string doesn't exist — endpoint may fall back to latest or return an error
- Unsupported ecosystem value — only 'npm' and 'PyPI' are accepted
- Transient OSV.dev upstream unavailability — may cause delayed or failed responses
- Payment failure (x402) — call not executed if USDC payment not settled

## How this service works

Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.

## Output

Returns a JSON object containing the checked package name, ecosystem, checked version, latest published version, whether the checked version is the latest, a deprecation notice if applicable, a list of vulnerabilities (each with GHSA/CVE IDs, summary, severity, published date, and first fixed version), a total vulnerability count, the data source attribution, and the timestamp of the check.
