Lower migration work
Keep familiar API patterns while connecting applications to additional model providers.
OpenAI Compatible API
OpenAI-compatible API access through a unified AI model gateway
HKR API helps developers keep familiar OpenAI-style API workflows while routing model calls through a centralized gateway for broader model coverage.
Why use an OpenAI-compatible API gateway
Centralized routing
Move model selection and routing into one gateway instead of duplicating logic across apps.
Team-ready management
Give teams one place to manage API access, model choices, and usage patterns.
Common use cases
Existing app migration
Move bots, tools, and internal apps toward a more flexible model gateway without a full rewrite.
Model fallback strategy
Adjust model routing at the gateway layer when cost, latency, or availability changes.
Company-wide API layer
Provide one AI API surface for multiple products or internal teams.
OpenAI-compatible API FAQ
What does OpenAI-compatible API mean?
It means the request and response patterns are designed to feel familiar to applications already built around OpenAI-style APIs.
Is HKR API only for OpenAI models?
No. HKR API is positioned as a model aggregation gateway for connecting and routing multiple LLM providers.
When should I use an OpenAI-compatible gateway?
Use one when multiple projects or model providers need a consistent API layer and easier long-term maintenance.
