How does your current customer base look? Do you see distinct tiers emerging for this feature? A straightforward pricing approach could split between small teams and enterprises, with usage limits and per-unit pricing over those limits. This way you could capture the nuance between small teams with simple API key vs. enterprises with different products requiring granular permissions. I wouldn't go with usage-based pricing from the start as you probably will not have proper numbers from the start to base how to price it, especially if serving customers with different sizes. Ultimately the best structure will depend on the needs and patterns of your existing users.
