})The Translation Layer That Just Works
Other gateways forward your errors. Zaguán actively translates your OpenAI-style calls to work optimally with each provider's specific API, parameters, and features. One integration, 500+ models.
CoreX: One Reliable Gateway for AI Models
CoreX gives developers one OpenAI-compatible API for 500+ models, without juggling provider keys, rewrites, rate limits, or surprise integration work.
Drop-In API
OpenAI-compatible by default
Change your base URL, keep your existing SDK, and start routing requests through CoreX in minutes.
Smart Translation
Provider-specific behavior handled for you
CoreX adapts requests for each provider’s API, parameters, and model quirks so your application code stays clean.
Provider Freedom
Avoid lock-in from day one
Test, compare, and switch models without rebuilding your integration every time the AI market changes.
