SDKs overview

Software Development Kits (SDKs) and libraries for VulDB enable developers to integrate vulnerability information and threat intelligence directly into their applications and systems. VulDB provides a RESTful API that returns data in JSON format, making it accessible from various programming languages. While VulDB maintains comprehensive API documentation, the ecosystem primarily relies on direct API calls and community-contributed libraries rather than officially maintained SDKs across multiple languages.

The API facilitates tasks such as querying vulnerability details, searching for specific Common Vulnerabilities and Exposures (CVEs), and retrieving threat intelligence feeds. Authentication for all API interactions is handled via API keys, which are obtained through a VulDB subscription. The API design emphasizes ease of use, with clear parameters and consistent response structures, allowing developers to build custom integrations for security monitoring, automated patch management, and vulnerability research.

Developers can leverage the API to:

  • Fetch detailed information about known vulnerabilities.
  • Integrate real-time threat intelligence into security operations centers (SOCs).
  • Automate vulnerability assessments and asset prioritization based on VulDB's proprietary data.
  • Develop custom dashboards and reporting tools for security posture management.

Official SDKs by language

VulDB's API is designed for direct consumption via standard HTTP requests. As of May 2026, VulDB does not provide officially maintained SDKs for multiple programming languages. However, the comprehensive API documentation includes examples for common languages like curl and Python, guiding developers on how to interact with the API directly.

The primary method for integration involves making direct HTTP requests to the API endpoints using an API key for authentication. This approach offers flexibility and allows developers to use their preferred HTTP client libraries in any language. The API adheres to REST principles, ensuring predictable resource-oriented URLs and standard HTTP methods for operations.

While a dedicated official SDK is not available, the developer experience is supported by detailed documentation on VulDB's website that outlines endpoint structures, request parameters, and expected JSON response formats. This enables developers to quickly construct API calls and parse responses in their chosen programming environment.

Installation

Since VulDB primarily relies on direct API calls rather than installable SDKs, installation typically involves setting up an HTTP client in your chosen programming language. For Python, this might involve libraries like requests. For other languages, similar HTTP client libraries are available.

To begin, ensure you have an active VulDB API subscription and an API key. The API key is essential for authenticating all requests to the VulDB API. Store your API key securely and avoid hardcoding it directly into your application's source code.

Python (using requests library):

First, install the requests library if you haven't already:

pip install requests

This library simplifies making HTTP requests in Python. For more information on requests, refer to its official documentation.

Other Languages:

  • JavaScript (Node.js/Browser): Use fetch API or libraries like axios.
  • PHP: Use GuzzleHttp client.
  • Java: Use java.net.http.HttpClient (Java 11+) or libraries like OkHttp.
  • Ruby: Use Net::HTTP or httparty gem.

The core requirement is an HTTP client capable of sending GET requests with custom headers for API key authentication and parsing JSON responses.

Quickstart example

This quickstart demonstrates how to fetch a vulnerability's details using the VulDB API with Python and the requests library. Replace YOUR_API_KEY and VULDB_ID with your actual API key and a specific VulDB vulnerability ID (e.g., 200000).

import requests
import json

# Replace with your actual VulDB API Key
API_KEY = "YOUR_API_KEY"
# Replace with the VulDB ID of the vulnerability you want to query
VULDB_ID = "200000"

# VulDB API endpoint for vulnerability details
API_URL = f"https://vuldb.com/?api.{VULDB_ID}"

headers = {
    "X-VulDB-ApiKey": API_KEY,
    "Accept": "application/json"
}

try:
    response = requests.get(API_URL, headers=headers)
    response.raise_for_status()  # Raise an HTTPError for bad responses (4xx or 5xx)

    vulnerability_data = response.json()

    print("Vulnerability Details:")
    print(json.dumps(vulnerability_data, indent=2))

    # Example of accessing specific fields
    if 'result' in vulnerability_data and vulnerability_data['result'] == 'success':
        vulnerability = vulnerability_data['vulnerability']
        print(f"\nTitle: {vulnerability.get('title')}")
        print(f"CVSSv3 Score: {vulnerability.get('cvss3score')}")
        print(f"Discovery Date: {vulnerability.get('discovery')}")
    else:
        print(f"API request failed: {vulnerability_data.get('message', 'Unknown error')}")

except requests.exceptions.HTTPError as http_err:
    print(f"HTTP error occurred: {http_err}")
except requests.exceptions.ConnectionError as conn_err:
    print(f"Connection error occurred: {conn_err}")
except requests.exceptions.Timeout as timeout_err:
    print(f"Timeout error occurred: {timeout_err}")
except requests.exceptions.RequestException as req_err:
    print(f"An unexpected error occurred: {req_err}")
except json.JSONDecodeError:
    print(f"Failed to decode JSON from response: {response.text}")

This snippet demonstrates:

  • Setting up the API endpoint and headers, including the X-VulDB-ApiKey.
  • Making a GET request using requests.get().
  • Handling potential HTTP errors and connection issues.
  • Parsing the JSON response and extracting key vulnerability details.

For a complete list of API endpoints and their parameters, consult the official VulDB API documentation.

Community libraries

While VulDB does not currently offer official SDKs, the developer community has created libraries and wrappers to simplify interaction with the API. These community-driven projects can provide language-specific abstractions over the raw HTTP requests, potentially reducing boilerplate code.

A notable example for Python is a community-maintained library that aims to provide an object-oriented interface to the VulDB API. Such libraries typically handle:

  • API key management.
  • Request construction for various endpoints.
  • JSON response parsing into native data structures.
  • Error handling.

Developers are encouraged to search public repositories like GitHub for vuldb api python or similar queries for other languages to find community contributions. When using community libraries, it is important to:

  • Review the source code: Ensure the library's implementation aligns with security best practices and correctly handles API keys.
  • Check maintenance status: Prefer libraries that are actively maintained and compatible with the latest VulDB API versions, as detailed in the VulDB API reference.
  • Understand licensing: Be aware of the license under which the library is distributed.

As the VulDB API is RESTful, developers can also build their own lightweight wrappers or integrate directly using standard HTTP client libraries available in virtually all programming languages, as outlined in the MDN Web Docs on HTTP.
