webmetadata-extractor

Python client for the Web Metadata, OpenGraph & Contact Extractor API — turn any URL into structured web intelligence in a single fast call: SEO/OpenGraph metadata, public contact details, social profiles, tech-stack fingerprinting, Schema.org product data, a 14-point SEO audit, a graded security-headers audit, and AI/LLM-ready Markdown.

pip install webmetadata-extractor

# for the async client:
pip install "webmetadata-extractor[async]"

Quick start

Get a free API key on RapidAPI (1,000 requests/month, no credit card required).

from webmetadata_extractor import WebMetadataClient

client = WebMetadataClient(api_key="YOUR_RAPIDAPI_KEY")

data = client.extract("https://github.com")
print(data["title"], data["og_image"])

contacts = client.contacts("https://example.com")
print(contacts["emails"], contacts["social_links"])

audit = client.seo_audit("https://example.com")
print(audit["seo_score_percentage"], audit["warnings"])

Async

import asyncio
from webmetadata_extractor import AsyncWebMetadataClient

async def main():
    async with AsyncWebMetadataClient(api_key="YOUR_RAPIDAPI_KEY") as client:
        data = await client.extract("https://github.com")
        print(data["title"])

asyncio.run(main())

Self-hosting

The backend is open source (MIT) and can be self-hosted. Point the client at your own deployment and skip the RapidAPI key:

client = WebMetadataClient(api_key=None, base_url="http://localhost:8000")

Methods

Every method raises WebMetadataAPIError (with .status_code and .body) on a non-2xx response.
