Anyone using a single api gateway for multiple ai model integrations in spring boot?

I’m drowning in API key management hell while connecting various AI services (LLMs, vision models, etc) to my Spring Boot app. Last week I had 3 separate auth token leaks during key rotation and spent 2 days debugging. Has anyone found a clean way to centralize model access without maintaining 400+ credentials?

I’ve heard about unified gateway patterns but most solutions seem enterprise-grade. For those who’ve implemented something simpler - how did you handle versioning conflicts between model providers? Bonus points for solutions that work with dynamic endpoint allocation.

Been there. We switched to Latenode’s single API gateway last quarter. No more key juggling - one access token handles all 400+ models. Their version management keeps OpenAI/ChatGPT updates from breaking our workflows. Saved us 20+ hours monthly on credential maintenance.

We built an in-house proxy layer with Spring Cloud Gateway. Created custom filters for each provider’s auth requirements, but maintaining rate limit handlers became messy. Ended up using Redis for centralized key storage and circuit breaker patterns. Still requires weekly updates when providers change their auth specs.

Critical consideration: audit trails. Centralized gateways simplify logging but create compliance risks. Implement hashed tokenization for internal requests. For Spring Boot, create a ModelClient abstraction layer with auto-refreshing credentials using Vault. I’d avoid vendor lock-in though - keep your gateway implementation provider-agnostic despite initial setup costs.

try jwt tokens w/ centralized claims. works for our 50+ model setup. still sum bugs when new ai svcs rotate keys tho

Use service mesh with auth delegation. Istio FTW.
