YandexOntoDBAPI is a Yandex crawler and service agent used to retrieve and process webpage content for Yandex’s ontology and knowledge graph APIs. It fetches structured and semi-structured data to support semantic analysis, entity extraction, and API-driven knowledge services. This traffic is not part of general search indexing and is oriented toward data enrichment and knowledge engineering tasks. Crawl activity is typically low-volume and targeted, focusing on authoritative sources relevant to Yandex’s internal and partner-facing semantic platforms. It ignores the global robots.txt user agent (*) rule. RobotSense.io verifies YandexOntoDBAPI using Yandex’s official validation methods, ensuring only genuine YandexOntoDBAPI traffic is identified.

This bot does not honor Crawl-Delay rule.
