How this service works

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

Output

Returns a JSON object with enriched entity data (company or person fields such as name, industry, location, employee count, job title, employer, etc.), payment settlement details (USDC amount charged), and a request tracking ID with a status URL.

Example use cases

Lead enrichment before sales outreach

“I have a lead named Jane Smith who works at Acme Corp — can you enrich her profile using Diffbot's Knowledge Graph by searching for her name, employer Acme Corp, and type Person, so I get her job title and other professional details?”

Company research by domain

“Look up the organization behind the domain openai.com in Diffbot's Knowledge Graph and give me everything they have — industry, headcount, location, and description.”

Verify and enrich a contact from email

“I have a person's email address, john.doe@example.com — can you use Diffbot's Knowledge Graph to find who this person is, their job title, and their employer?”

When to prefer

Choose this endpoint when you need structured, comprehensive entity enrichment at scale from Diffbot's curated 10B+ entity Knowledge Graph, especially when you have partial identifiers (name, URL, or email) and need authoritative company or person profiles. Prefer this over generic web scraping when you want structured, pre-parsed firmographic or professional data without building your own extraction pipeline. The pay-per-call x402 model makes it suitable for low-to-medium volume enrichment without a subscription commitment.

Side effects

No entity match found for the provided identifiers (low confidence or unknown entity)
Match confidence below the specified threshold — returns empty or partial results
Invalid entity type value (must be 'Person' or 'Organization')
Missing required identifiers — at least one of url, name, or email must be provided
Payment failure or insufficient funds via x402 protocol
Rate limiting or credit exhaustion on the Diffbot side
Refresh flag set to true incurs higher cost (100 credits vs 25)
