6. Is there free quota?
New users receive a certain amount of free testing quota after registration for development and debugging.
7. 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.
8. How to set fallback models?
Use fallback_models parameter:
json
{
"model": "doubao-seed-2-0-pro-260215",
"fallback_models": ["doubao-seed-2-0-lite-260215", "doubao-seed-2-0-mini-260215"]
}System will automatically try fallback models when primary model is unavailable.
9. Is streaming supported?
Yes. Set stream: true to enable streaming. See Streaming for details.
10. How to get technical support?
