Add one stable API layer between your SaaS product and multiple AI model providers. I’ll build a focused gateway that keeps provider calls behind a consistent interface, supports streaming, and adds the routing, fallback, key handling, and usage visibility your product needs. This is for teams that want to reduce provider-specific code without commissioning an entire AI platform. What’s included: • One documented, OpenAI-compatible REST endpoint where feasible • Integration for up to three agreed model providers • Configurable routing, provider fallback, and streaming responses • Secure provider-key handling plus practical request and error controls • Usage and error logs, automated tests, and deployment documentation Send me your current provider setup or requirements and I’ll tell you the cleanest way to add a gateway.
