Use AnyInt
Connect agent tools or build applications with one gateway to multiple AI model families.
AnyInt gives agent tools and applications one public gateway to multiple AI model families. Start from the task you want to complete rather than learning every API family first.
Connect an agent tool
Configure Claude Code, Codex, Gemini CLI, CC-Switch, or another compatible client.
Build with the API
Send a first request, discover model IDs, and choose the compatible API family for your application.
Popular starting points
Claude Code
Stable Anthropic-compatible setup.
Codex
OpenAI Responses setup, currently Beta.
Gemini CLI
Stable Gemini-compatible setup.
Create an API key
Open the AnyInt console and create a key for your tool or application.

What AnyInt provides
| API family | Use it for |
|---|---|
| OpenAI-compatible | Existing SDK clients, Chat Completions, and many custom-provider agent tools |
| OpenAI Responses | Agent clients that specifically require the Responses wire format |
| Anthropic-compatible | Claude-style messages, content blocks, and token counting |
| Gemini-compatible | Gemini-native content, streaming, and function declarations |
| Media APIs | Image and video generation workflows |
| AI Music | Song generation, transformation, lyrics, stems, and media tasks |
Before production use
- Keep API keys out of source control and client-visible code.
- Discover the model IDs available to the same key used by the application.
- Check whether the selected route is Stable, Beta, or pass-through.
- Verify streaming, tool calling, async tasks, and error handling required by the workload.
- Record the API family, model ID source, and fallback behavior next to the integration.
Use Agent Setup Troubleshooting for agent clients, or Errors and Limits for direct API integrations.
