Diffbot
Diffbot operates an automatic structured-extraction crawler that converts web pages into typed entities (Article, Product, Organisation, Event). Diffbot resells the resulting dataset and Knowledge Graph; AI-model training is one of several downstream uses.
At a glance
- Operator: Diffbot
- Type: Scraper
How Centinel checks it
- User agent: The request calls itself this crawler. Anyone can send the same string.
Diffbot publishes nothing Centinel can check a source against, so a match reports the name and leaves the source unconfirmed. The match tokens, verification domains, and address feeds are not published here.
Allowing or blocking it
The crawler object in the /validate response sets access_allowed to true only for a verified source that your tenant allowlists. A policy rule can allow or block this crawler by its category, Scraper.
