What APIMart is
APIMart is a gateway that normalises several model providers behind one endpoint and one API key, using an OpenAI-compatible request format so existing clients work without rewriting integration code. Chat, image and video models from a range of providers are reachable through it.
What you can do with it
- Call several providers with one integration
- Keep an OpenAI-compatible client unchanged
- Compare models on cost and latency
- Add fallback vendors behind one key
- Prototype before committing to a provider
Who it is for
- Development teams wanting provider flexibility
- Products that need fallback capacity
- Teams comparing model costs
What to watch out for
- Compatibility layers occasionally diverge from the real provider APIs in edge cases
- Availability figures such as uptime percentages are vendor claims, not guarantees
- Prompts and files pass through an intermediary, so review its data handling
- Model names in the catalogue change as providers release new versions
