Overview

VulDB is a vulnerability database API that lets you query detailed information about security vulnerabilities, CVEs, and threat intelligence data. You can retrieve vulnerability entries by ID, search across their database, and even set up automated bots for continuous monitoring. It is a great resource for security researchers and developers building threat-tracking tools.

Beginner Tip

Start with a simple GET request using your API key to fetch a specific CVE entry by its VulDB ID. Keep in mind that the free tier has strict rate limits, so cache responses locally to avoid hitting the quota quickly.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

JSON Response · Illustrative

{
  "status": "success",
  "data": {
    "result": "Data from VulDB",
    "description": "VulDB API allows to initiate queries for one or more items along with transactional bots",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

id Unique VulDB identifier for the vulnerability entry

entry.title Human-readable title describing the vulnerability

cve.id Official CVE identifier (e.g., CVE-2023-12345) if assigned

cvss.score CVSS score from 0 to 10 indicating severity of the vulnerability

entry.summary Brief description of the vulnerability and its potential impact

affected.vendor Name of the vendor or organization whose software is affected

Implementation Example

Request skeleton. The URL below is this API's documentation page, not a live endpoint — swap in the path you need from the provider's docs before running it.

Request

const url = "https://vuldb.com/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

401 Unauthorized Missing or invalid API key in the request header

✓ Add the X-VulDB-ApiKey header with your valid API key obtained from your VulDB account

429 Too Many Requests You have exceeded the rate limit for your subscription tier

✓ Slow down your request frequency and cache results locally; upgrade your plan if you need higher limits

Empty results array The CVE ID or search query did not match any entries in the database

✓ Double-check the CVE ID format (e.g., CVE-2023-12345) and confirm it exists in VulDB before querying

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
