How do you call the DeepSeek V4 Flash API?

How do you call the DeepSeek V4 Flash API?

Two variables change: base_url points at the gateway, api_key becomes the token we issue. Nothing else.

1. Confirm the model identifier：Use deepseek-v4-flash in the model configuration and verify its current availability in the panel before making a call.
2. Confirm the assigned group：Check the group assigned to the account and its corresponding multiplier. The final price equals the model benchmark price multiplied by that multiplier.
3. Check real-time pricing：Call the panel pricing API or verify the model price in the console. Do not estimate costs based solely on a static page.
4. Configure access credentials：Create and save credentials in the proxy service console. Do not commit credentials to a code repository or include them in frontend code.
5. Validate with production-like samples：Use samples with input and output lengths close to real-world usage to validate the response format, context requirements, time to first token, and final bill.

import json
from urllib.request import urlopen

PRICING_URL = "https://api.openlux.ai/api/pricing"
MODEL_ID = "deepseek-v4-flash"

with urlopen(PRICING_URL, timeout=15) as response:
    payload = json.load(response)

# 接口返回结构可能随面板更新；递归查找包含目标模型名的对象。
def find_model(value):
    if isinstance(value, dict):
        if value.get("model") == MODEL_ID or value.get("id") == MODEL_ID or value.get("name") == MODEL_ID:
            return value
        for child in value.values():
            result = find_model(child)
            if result is not None:
                return result
    elif isinstance(value, list):
        for child in value:
            result = find_model(child)
            if result is not None:
                return result
    return None

model = find_model(payload)
if model is None:
    raise SystemExit(f"未在定价接口响应中找到 {MODEL_ID}")

print(json.dumps(model, ensure_ascii=False, indent=2))
print("请结合账户所在分组倍率计算最终价格。")
