X AI Integration

Gateway Integration

Create a Helicone account

Log into helicone or create an account. Once you have an account, you can generate an API key.

Create an X AI account

Log into https://console.x.ai/ or create an account. Once you have an account, you can generate an API key from your dashboard.

Set HELICONE_API_KEY and XAI_API_KEY as environment variables

HELICONE_API_KEY=<your API key>
XAI_API_KEY=<your API key>

Modify the base URL and add Auth headers

Replace the following X AI URL with the Helicone Gateway URL:https://api.x.ai/v1/chat/completions -> https://x.helicone.ai/v1/chat/completionsand then add the following authentication headers:

Authorization: Bearer $XAI_API_KEY
Helicone-Auth: Bearer $HELICONE_API_KEY

Now you can access all the models on X AI with a simple fetch call:

Example

curl --request POST \
      --url https://x.helicone.ai/v1/chat/completions \
      --header "Content-Type: application/json" \
      --header "Authorization: Bearer $XAI_API_KEY" \
      --header "Helicone-Auth: Bearer $HELICONE_API_KEY" \
      --data '{
          "model": "grok-4-latest",
          "messages": [
              {
                  "role": "system",
                  "content": "You are a robot called Marvin with a brain the size of the planet."
              },
              {
                  "role": "user",
                  "content": "Say this is a test"
              }
          ],
          "temperature": 1
        }'
