Production readiness checklist
Python setup snapshot
Start with the smallest possible chat completion, then move the key to your server-side secret manager before production.
from openai import OpenAI
client = OpenAI(
api_key="your-xai-key",
base_url="https://api.x.ai/v1"
)
response = client.chat.completions.create(
model="grok-4-mini",
messages=[{"role": "user", "content": "Summarize xAI API billing risks in 5 bullets."}],
)
print(response.choices[0].message.content)cURL smoke test
Use this to verify endpoint, auth header, model name, response shape, and quota before adding SDK abstractions.
curl https://api.x.ai/v1/chat/completions \
-H "Authorization: Bearer $XAI_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "grok-4",
"messages": [{"role": "user", "content": "Hello from yangmao.ai"}]
}'Free API and pricing notes
未确认当前长期免费额度；以 xAI Console 为准
Search demand for Grok free credits is high, but many $150 credit or promo-code posts are stale. For production, trust only docs.x.ai and the xAI Console billing page.
Access and production risk
Relay or proxy may be needed
Mainland China access, signup, and billing reliability should be validated case by case; prepare Qwen, DeepSeek, GLM, or a compliant API-gateway fallback for China-facing products.
Decision checklist
Check xAI Grok API free credits and rate limits.
Compare same-category providers and Mainland China access needs.
Pick the provider with the clearest no-card/free API path for testing.
