OpenRouter

export OPENROUTER_API_KEY="sk-or-v1-..."

from ai_query import generate_text
from ai_query.providers import openrouter

result = await generate_text(
    model=openrouter("openai/gpt-4o"),
    prompt="Explain machine learning in simple terms."
)

result = await generate_text(
    model=openrouter("anthropic/claude-3.5-sonnet"),
    prompt="Write a creative story.",
    provider_options={
        "openrouter": {
            "temperature": 0.9,
            "max_tokens": 1000
        }
    }
)

## Tool Calling

Tool calling works the same as with other providers:

```python
from ai_query import generate_text
from ai_query.providers import openrouter, tool, Field

@tool(description="Search the web")
async def search(query: str = Field(description="Search query")) -> str:
    return f"Results for: {query}"

result = await generate_text(
    model=openrouter("openai/gpt-4o"),
    prompt="Search for the latest Python news",
    tools={"search": search}
)

from ai_query import stream_text
from ai_query.providers import openrouter

result = stream_text(
    model=openrouter("openai/gpt-4o"),
    prompt="Write a poem about coding."
)

async for chunk in result.text_stream:
    print(chunk, end="", flush=True)
