Its primary user-agent pattern is YaK.
YaK is not independently verified with Low confidence. The identity type is Observed, and the evidence basis is observed traffic patterns and user-agent evidence.
Robots.txt behavior is not currently confirmed.
YaK should be handled according to the site owner’s AI crawler policy, with allow, block, or rate-limit rules applied deliberately.

Behavior and handling
- Common Use
- YaK is used for AI crawler discovery, assistant retrieval, AI search support, or model-related web access.
- Detection Notes
- YaK traffic is primarily detected by the `YaK` user-agent pattern. Compare source IPs, reverse DNS, request paths, and crawl cadence before trusting the traffic.
- Respects robots.txt
- Unknown
- Spoofing Risk
- YaK has high spoofing risk because the pattern is low-confidence or observation-based; do not trust the user-agent by itself.
- Risk
- Neutral
- Recommended Handling
- Depends
