How do you call the grok-4.5 API?

For an existing project this is a configuration change, not a code change: new base_url, new api_key, done.

1. Confirm the account group：First, confirm the current account's group and corresponding multiplier in the platform panel. The actual billed price is the benchmark price multiplied by that multiplier.
2. Verify the model name：Confirm in the available model list that the model name used for the request is grok-4.5.
3. Obtain integration details：Obtain the request endpoint, authentication credentials, and request format for the current account from the platform panel. Do not use the environment variable placeholder values from the example in a production environment.
4. Make a minimal request：Start with a short-text request to verify model availability, response format, and the actual billing record.
5. Check billing and latency：Cross-check request token usage, the group multiplier, and billing records. Performance data such as time to first token must be measured in your own network environment.

Complete code example

import json
import os
from urllib.request import Request, urlopen

api_url = os.environ["API_URL"]  # 替换为面板提供的实际请求地址
api_key = os.environ["API_KEY"]  # 替换为面板提供的实际鉴权凭证

payload = {
    "model": "grok-4.5",
    "messages": [
        {"role": "user", "content": "请用一句话说明这段请求用于连通性测试。"}
    ]
}

request = Request(
    api_url,
    data=json.dumps(payload).encode("utf-8"),
    headers={
        "Content-Type": "application/json",
        "Authorization": f"Bearer {api_key}"
    },
    method="POST"
)

with urlopen(request, timeout=60) as response:
    print(response.read().decode("utf-8"))
