How this service works

Knowledge Graph — search 10B+ entities and enrich company/person records.

Output

Returns a JSON object containing matched entity records from Diffbot's Knowledge Graph (companies, people, or other entity types), along with pagination metadata, payment settlement details (USDC amount charged), and a request ID for status tracking. The 'data' field holds the entity results matching the DQL query.

Example use cases

Lead enrichment for sales pipeline

“I have a list of company names from our CRM — can you look up each one in Diffbot's Knowledge Graph and pull back their headquarters city, industry, employee count, and founding year so I can prioritize outreach?”

Competitor landscape research

“Search Diffbot's Knowledge Graph for all organizations in the 'fintech' industry located in New York City — I want to see up to 50 results with their names, descriptions, and website URLs.”

Executive contact discovery

“Find people in Diffbot's Knowledge Graph who hold a 'Chief Technology Officer' title at companies with more than 500 employees — give me their names and employer details, up to 30 results.”

When to prefer

Choose this endpoint when you need to search or enrich records against a massive, structured knowledge graph of 10B+ real-world entities (companies, people, organizations) using structured DQL queries. It is ideal for firmographic enrichment, lead research, and entity lookup at scale. Prefer this over web scraping or simpler business search APIs when you need structured, canonical entity data with rich facts and relationships, and when you are comfortable with per-call USDC micropayment billing via the x402 protocol.

Side effects

Invalid DQL query syntax returns an error with no results
Querying an entity type that doesn't exist yields empty data
Pagination offset beyond result set returns empty array
Malformed JsonPath filter expression causes a filter error
Payment authorization failure prevents the query from executing
Rate limiting or network timeout from the upstream Diffbot API
