Introduction
The X-AI Grok API enables developers to work seamlessly with the Grok family of AI models—Grok-4, Grok-4.1, and Grok-Code-Fast—inside applications. By routing requests through Wisdom-Gate, you get a single interface for all models while benefiting from significantly lower usage costs.
Understanding the X-AI Grok API
Core Models Overview
- Grok-4: General-purpose model suited for complex reasoning and natural language understanding.
- Grok-4.1: Enhanced version with improved factual grounding and accuracy.
- Grok-Code-Fast: Engineered for faster code generation and developer-centric tasks.
Unified Access via Wisdom-Gate
Wisdom-Gate provides developers with a consistent endpoint and payload format across all Grok models. The key advantages:
- Single Base URL: https://wisdom-gate.juheapi.com/v1
- Consistent schema for requests and responses means fewer integration changes when switching models.
- Streamlined authentication with one API key.
Key Features and Benefits
Lower Pricing
Using Wisdom-Gate vs. OpenRouter reduces cost per million tokens, both input and output.
| Model | OpenRouter Input / Output | Wisdom-Gate Input / Output | Savings |
|---|---|---|---|
| GPT-5 | $1.25 / $10.00 | $1.00 / $8.00 | ~20% |
| Claude Sonnet 4 | $3.00 / $15.00 | $2.00 / $10.00 | ~30% |
| grok-4 | $3.00 / $15.00 | $2.00 / $10.00 | ~30% |
Model Flexibility
Change only the model field to switch between Grok-4, Grok-4.1, and Grok-Code-Fast.
Scalable Performance
Optimized for high-concurrency requests and low-latency responses, supporting production-grade deployments.
Getting Started
Prerequisites
- Get your API key from Wisdom-Gate.
- Install curl or configure your preferred HTTP client.
Base URL and Endpoints
- Base: https://wisdom-gate.juheapi.com/v1
- Endpoint (chat completions):
/chat/completions
Example Integration Steps
Step 1: Setup Request
Prepare the POST request with required headers and JSON payload.
Step 2: Choose Model
Select "grok-4", "grok-4.1", or "grok-code-fast" in the model parameter.
Step 3: Parse Response
Handle response JSON to extract model output.
Sample Request
Simple Chat Example
curl --location --request POST 'https://wisdom-gate.juheapi.com/v1/chat/completions' \
--header 'Authorization: YOUR_API_KEY' \
--header 'Content-Type: application/json' \
--header 'Accept: */*' \
--header 'Host: wisdom-gate.juheapi.com' \
--header 'Connection: keep-alive' \
--data-raw '{
"model":"grok-4",
"messages": [
{
"role": "user",
"content": "Hello, how can you help me today?"
}
]
}'
Switching Models Example
Change only:
"model": "grok-4.1"
Or:
"model": "grok-code-fast"
Pricing Deep Dive
For developers processing millions of tokens monthly, the ~30% savings on Grok models scale to thousands of dollars saved annually.
Example: 10M tokens with grok-4 output cost:
- OpenRouter: $150.00
- Wisdom-Gate: $100.00 Savings: $50.00
Best Practices
Request Formatting Tips
- Match messages array format exactly.
- Use clear role definitions (user, assistant, system).
Rate Limits Awareness
Review Wisdom-Gate documentation for rate limits to avoid throttling.
Error Handling
Catch network errors and read error fields in API JSON responses.
Use Cases
Conversational Agents
Build customer support bots with Grok-4's reasoning ability.
Code Assistants
Use Grok-Code-Fast for quick, context-aware code generation.
Knowledge QA Systems
