Knowledge Graph API - Company, People and News Data Search

Knowledge Graph API turns a global knowledge graph of organizations, people and articles into a clean, structured export. Write one query, choose an entity type, and export structured records - company firmographics, employee profiles, or news with sentiment - as JSON, CSV or Excel.

Bring your own API token and pay only for the records you keep.

Why use this actor?

• Three entity types, one query - search organizations (companies), people, or articles (news) from a single actor.
• Simple query language - filter by name, city, industry, employee count or current employer with plain fields, or drop into the advanced query for full control.
• Structured entity output - company name, website, employee count, industry and location; person name, current title and employer, skills and location; article title, author, source, date and sentiment - parsed into flat columns.
• Pay per result - you are charged only for the entity records actually returned, up to 1,000 per run.
• No proxies, no blocks - data comes through a stable API, so runs are fast and reliable.

Use cases

• Lead generation and TAM building - build company target lists by industry, location and size.
• People search - find people by current employer, title or location for recruiting and sourcing.
• Media monitoring - pull recent articles about a company or topic with sentiment scores.
• Market and competitor mapping - profile the organizations in a sector and rank them by size.
• CRM enrichment - append firmographics and entity records to your existing accounts.

Input

Configure everything from the visual editor - every filter is a proper field, no code needed. Example JSON input:

{
  "entityType": "Organization",
  "industry": "Artificial Intelligence Companies",
  "city": "San Francisco",
  "minEmployees": 100,
  "maxResults": 50,
  "apiKey": "YOUR_API_TOKEN"
}

Search people at a company:

{
  "entityType": "Person",
  "employer": "Google",
  "city": "London",
  "maxResults": 50,
  "apiKey": "YOUR_API_TOKEN"
}

Advanced query for full control:

{
  "entityType": "Organization",
  "query": "industries:\"Financial Services Companies\" nbEmployees>5000",
  "maxResults": 100,
  "apiKey": "YOUR_API_TOKEN"
}

Output

One clean JSON object per entity (fields depend on entity type):

{
  "name": "Acme AI",
  "entityType": "Organization",
  "homepageUri": "https://acme.ai",
  "nbEmployees": 240,
  "industries": ["Artificial Intelligence Companies"],
  "city": "San Francisco",
  "country": "United States",
  "entityUri": "https://example.com/entity/EABCDEF",
  "entityId": "EABCDEF"
}

Do I need an API key?

Yes. This actor calls a knowledge graph API on your behalf, which requires your own API token. Sign up self-serve with the provider to get a free monthly credit allowance and a token, paste it into the input, and run. Your token is stored securely and never logged.

Pay per result

You pay only for the entity records the actor actually returns - no subscriptions, no minimums. Set Maximum results to cap each run's spend exactly. Each returned entity also consumes credits against your own token, so keep the cap only as high as you need.

FAQ

What is the Knowledge Graph API?

It is a data API that answers structured queries against a knowledge graph of organizations, people and articles. You write a query with a simple query language, pick an entity type, and it returns matching entity records - firmographics for companies, profiles for people, and metadata plus sentiment for articles. This actor runs that search and exports the matches as JSON, CSV or Excel.

What entity types can I search?

Three: Organization (companies, with firmographics and industries), Person (people, with current title, employer and skills), and Article (news, with author, source, date and sentiment). Set the Entity type field to choose.

What filters can I use?

Built-in fields for name, city, industry, minimum employee count and current employer. For any other supported attribute, use the Advanced query field to pass raw query-language conditions such as revenue>1000000000 or educations.{institution.name:"Stanford University"}.

How does the query language work?

Each condition is attribute:value, combined with spaces, for example type:Organization industries:"Artificial Intelligence Companies" locations.city.name:"San Francisco". Numeric comparisons use operators such as nbEmployees>5000. Nested conditions use braces, for example employments.{employer.name:"Google" isCurrent:true}. The entity type is added for you from the Entity type field.

How many results can I get per run?

Up to 1,000 entity records per run, paged automatically. The API caps deep paging at an offset of 10,000, so for larger universes split the search by industry, location or size across multiple runs.

How much does it cost?

Pricing is pay-per-result: a small fixed amount per entity record returned, plus standard Apify platform usage, plus your own API credits against your token. A run that returns nothing costs almost nothing.

Can I run this on a schedule?

Yes. Use Apify Schedules to run it daily or weekly and connect the dataset to Zapier, Make, n8n, webhooks or the API to push new records into your CRM or data warehouse.

Is this legal?

The actor returns organization, people and article data retrieved through a licensed knowledge graph API using your own credentials. It focuses on business and public web data.
