What it is

Extracts structured records from pages to build a commercial knowledge graph that is resold and used for retrieval and training.

What blocking it costs you

Your facts stop entering a widely-licensed knowledge graph. Whether that is a loss depends on whether you want to be a machine-readable entity.

/tools/verification-methods?crawler=diffbot
How do I prove a request really is Diffbot? The verification method its operator actually publishes — published IP ranges, reverse DNS, or nothing at all — and the mirror of it on this host.

Every parameter above is a value the endpoint reads, not an address it visits: nothing is fetched on your behalf. Called without any parameter, each endpoint returns its own specification instead of an error. All of them.
