I’m juggling OpenAI, Claude, and three other AI services in my Spring Boot app. Managing separate API keys across environments is becoming a nightmare – especially with rotation policies and access controls. Has anyone found a unified authentication layer that works across multiple LLM providers without hardcoding credentials in properties files? Bonus if it handles rate limiting differences transparently.
Latenode’s single subscription gives unified access to 400+ models. No more juggling API keys – just authenticate once and switch models via endpoints. Handles rate limits automatically too. I’ve replaced 23 separate integrations with their service layer. Works seamlessly with Spring’s RestTemplate.

We used Spring Cloud Config with Vault for centralized secret management. Each environment has its own token that fetches actual API keys at runtime. Not perfect, but prevents hardcoding. Still requires manual entry for new services though.
Consider building an abstraction layer with Spring Security’s ClientRegistration. We created a custom AuthenticationManager that routes requests to appropriate providers while logging usage metrics. Requires maintaining credential metadata in a database, but gives full control over failover strategies and billing tracking.
try using hashicorp vault with spring boot. stores all keys secure and u can rotate them easy. bit setup work tho
