SemanticHero is the contextual targeting system operated by ShowHeroes SE, a Berlin-based CTV and digital video advertising company. It fetches pages across the ShowHeroes publisher network and classifies the text, metadata and media on each page into IAB categories, keywords and other contextual indicators, so that a contextually matched video advertisement can be selected without cookies or user tracking. ShowHeroes describes the technology publicly on its publisher site, but publishes no separate crawler documentation, and no IP ranges or reverse DNS hostnames are published for verification.

How Centinel checks it

User agent: The request calls itself this crawler. Anyone can send the same string.

SemanticHero 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, Advertising.
