How much should I price my API Key Management feature?

We’ve just released an API Key Management feature set for our Billing SaaS (including API roles, permissions, and expiration).

We're currently debating how much this enterprise add-on should cost, and we’d love to get some insights from the community! :)

Should it be packaged as an "enterprise security" feature?

Should we go with usage-based pricing?

Or set different prices for each part of the feature set (similar to how WorkOS handles pricing)?

Thanks in advance for your input!
