FastCron is a webhook callback used for webhook delivery, payment notifications, service callbacks, and server-to-server integration events.
Its primary user-agent pattern is FastCron; related patterns include FastCron online cron job service.
FastCron is Unverified at the identity-evidence level. The listed identity remains useful for detection, but this record does not currently contain authoritative evidence sufficient to authenticate the identity claim.
Robots.txt behavior is not currently confirmed.
FastCron should be reviewed against site policy, source evidence, crawl rate, and requested paths before a permanent allow or block rule is created.
