Step 2: Select a Model and Make API Calls

Once you have your XRoute API KEY, you can select from over 60 large language models available on XRoute.AI and start making API calls. The platform’s OpenAI-compatible endpoint ensures that you can easily integrate models into your applications using just a few lines of code.

Here’s a sample configuration to call an LLM:

curl --location 'https://api.xroute.ai/openai/v1/chat/completions' \
--header 'Authorization: Bearer $apikey' \
--header 'Content-Type: application/json' \
--data '{
    "model": "gpt-5",
    "messages": [
        {
            "content": "Your text prompt here",
            "role": "user"
        }
    ]
}'

With this setup, your application can instantly connect to XRoute.AI’s unified API platform, leveraging low latency AI and high throughput (handling 891.82K tokens per month globally). XRoute.AI manages provider routing, load balancing, and failover, ensuring reliable performance for real-time applications like chatbots, data analysis tools, or automated workflows. You can also purchase additional API credits to scale your usage as needed, making it a cost-effective AI solution for projects of all sizes.
