# CodePulse API – CVE Security Vulnerability Lookup

> CodePulse API – CVE Security Vulnerability Lookup is a paid API for AI agents from codepulse-api.hahavoid0.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Checks a specific package version against known CVE/GHSA vulnerability databases and returns whether it is vulnerable along with applicable advisory IDs.

## Facts

- Endpoint: POST https://codepulse-api.hahavoid0.workers.dev/security/cve
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/codepulse-api-cve-security-vulnerability-lookup-8c807728
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_VUV_qrb0Ou-OS3Kf4w4g6

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 codepulse-api-cve-security-vulnerability-lookup-8c807728 -d '<json body>'
```

Example prompt: Can you check if lodash version 4.17.15 on npm has any known CVEs or security vulnerabilities?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call CVE/GHSA check for a specific package-version pair across npm, PyPI, Go, or Crates ecosystems without managing API keys. Prefer it over manual NVD queries or full SCA tools when you need a lightweight, agent-callable lookup in an automated pipeline at low cost ($0.02 USDC per call).

## Known failure modes

- Unsupported ecosystem returns supported:false with no CVE data
- Unknown or misspelled package name may return no results or low confidence
- Very new vulnerabilities may not appear if data_as_of date lags behind disclosure
- Malformed version strings may cause lookup failures
- Network or worker errors return non-200 HTTP responses

## How this service works

Checks package names and versions against the free open-source vulnerability database OSV.dev.

## Output

Returns a JSON object indicating whether the package version is vulnerable (true/false), a list of CVE/GHSA advisory IDs if vulnerable, a confidence level (e.g. 'high'), the data freshness date, and a disclaimer. Also includes warnings and a 'supported' flag indicating whether the ecosystem/package is covered.
