When you search a brand, person, or place, Google often shows a knowledge panel — a box with a title, image, description, and key facts. That panel is powered by the Knowledge Graph, Google’s database of entities and their relationships.
What’s in it
For an entity query, the panel typically includes:
- Title and description (e.g. “Tesla — American electric vehicle maker”)
- Description (often from an authoritative source)
- Attributes — founded, headquarters, CEO, etc.
- Links to official site and profiles
Why it matters
The Knowledge Graph shapes how users perceive an entity before they click anything. For brands, monitoring your panel matters; for apps, entity data is useful for enrichment, disambiguation, and answering factual queries.
Getting it via a SERP API
A SERP API that parses the live page returns the knowledge panel alongside organic results. With serp.cheap, entity queries include a knowledgeGraph object:
import requests
data = requests.post("https://api.serp.cheap/v1/search",
headers={"X-API-Key": "YOUR_KEY"},
json={"q": "Tesla", "gl": "us"}).json()
if data.get("knowledgeGraph"):
print(data["knowledgeGraph"]) # title, description, attributesThe knowledgeGraph field is present when Google shows a knowledge panel for the query (brand, person, place); for generic queries it may be empty.
Knowledge Graph vs the official KG Search API
Google’s own Knowledge Graph Search API returns entries from its entity database, not what appears on the live SERP, and is limited. If you want the panel as shown to users, a SERP API is the practical route — and it returns organic results in the same call.
