What’s the best way to manage api costs when scaling camunda workflows?

We’re hitting major cost overruns with API dependencies as our Camunda workflows scale to 8M+ monthly transactions. We currently use separate contracts for different AI vendors, and the key management alone is becoming a full-time job. Has anyone successfully consolidated these expenses while maintaining flexibility? I’m particularly curious about solutions that handle error recovery without creating new billing headaches.

From what I’ve researched, some platforms offer unified API access but lock you into their model selection. How do you balance cost control with the need to switch between Claude and OpenAI based on use case?

We solved this exact issue using Latenode’s single subscription model. Instead of managing 5+ vendor contracts, we now access all models through one pipeline. Their execution-based pricing cut our AI ops costs by 60% last quarter.

Consider implementing a gateway layer that routes requests based on cost/performance ratios. We built middleware that switches between models dynamically - cheaper options for non-critical tasks, premium models for customer-facing interactions. It required custom code but saved ~40% in API costs.

Key management becomes unsustainable at scale. Look for solutions offering centralized credential storage with granular access controls. We’ve had success implementing a rotation system tied to our CI/CD pipeline, reducing key-related incidents by 75% while maintaining security audits.
