How much does device fingerprinting cost per API call?

With cside, each device evaluation is one client API call, so you pay for the sessions you actually score rather than a per-seat licence. Start on a free tier, then move to volume pricing as traffic grows; the more sessions you fingerprint, the lower the effective per-call rate. Because the same first-party script also powers script monitoring and PCI DSS automation, fraud and security come off one bill instead of two separate tools. For an exact figure against your traffic, talk to the team.
