How do you handle API keys when an AI agent needs access to multiple external services?

Reddit r/AI_Agents News

Summary

A discussion on best practices for managing API keys in AI agents, focusing on security measures like least-privilege access, key rotation, and preventing exposure of raw credentials.

I’m experimenting with an agent that needs to call several external services, and API key management is starting to get messy. Do you keep separate keys for every service and store them behind a proxy/secret manager, or use some kind of integration layer? I’m mainly thinking about least-privilege access, key rotation, and making sure the agent never sees raw credentials. Curious what people are actually doing in production.
