help Frequently Asked Questions

Is the SiliconFlow API free to use?

Yes! SiliconFlow provides free API access or free developer credits. Refer to the model list table above for context window and rate limit details.

Do I need a credit card to get an API key?

Most free tier providers in our directory (including SiliconFlow) do not require a credit card for developer key activation. Check their official developer portal for exact signup requirements.

What happens if I hit the rate limit?

If your application exceeds the RPM (Requests Per Minute) or RPD (Requests Per Day) quota, the API will respond with an HTTP 429 status code until your quota window resets.
