Technical details
Endpoint
POSThttps://diffbot-kg.mpp.paywithlocus.com/diffbot-kg/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search across Diffbot's 10B+ entity knowledge graph using structured DQL queries — ideal for finding companies, people, or organizations by specific attributes like location, industry, or name. Prefer this over the Enhance endpoint when you are doing broad discovery queries rather than enriching a known entity. Best for business intelligence, lead generation, entity lookup, and knowledge graph exploration tasks.
Side effects
- Invalid DQL query syntax returns a 400 error
- Query returns 0 results if entity type or field names are misspelled
- Pagination offset beyond result set returns empty list
- Unsupported jsonmode value causes a format error
- Missing required 'query' field returns validation error
