4. Is API compatible with OpenAI?
Yes, AI-TokenHub API is fully compatible with OpenAI API format. You can use OpenAI SDK directly, just modify base_url:
python
from openai import OpenAI
client = OpenAI(
base_url="https://ai-tokenhub.com/api/v1",
api_key="$YOUR_API_KEY"
)5. How does billing work?
- Charged by token usage
- Different models have different pricing
- View real-time usage and costs in console
- Supports recharge and quota management
6. How to handle rate limits?
When rate limit is exceeded, API returns 429 error. Recommendations:
- Implement retry mechanism, wait and retry
- Batch process requests to reduce request count
- Use streaming to reduce concurrency
See API Key Limits for details.
When the primary model is unavailable, the system automatically tries fallback models.
7. Is streaming supported?
Yes. Set stream: true to enable streaming. See Streaming for details.
8. How to get technical support?
- Check Errors and Debugging documentation
- Login to console to view usage logs
- Contact customer service for help
