Troubleshooting Guide
Solutions to common issues when using WaveSpeedAI.
Generation Failed
What should I do?
- Check your parameters — Some models have specific requirements (e.g., image dimensions, file formats). Read the model’s README.
- Check your balance — Ensure you have sufficient credits.
- Try again — Temporary issues may resolve on retry.
- Report the issue — Copy the Task ID from Predictions and contact support.
Failed requests are automatically refunded within 3 hours.
How to report issues
If you believe there’s a technical problem:
- Go to Predictions
- Copy the Task ID (shown in the ID column)
- Provide it to our support team

API Key Issues
My API key doesn’t work. Why?
API keys require a top-up to activate. Keys generated before your first top-up will not work. Add credits to your account, then try again.
Also check:
- The key is copied correctly (no extra spaces)
- The key hasn’t been deleted or regenerated
- You’re using the correct header format:
Authorization: Bearer YOUR_API_KEY
Rate Limit Errors
I’m getting “Too Many Requests” errors.
You’ve hit your tier’s rate limit. Options:
- Wait — Limits reset every minute.
- Upgrade — Add credits to reach the next tier threshold.
- Optimize — Reduce concurrent requests or add delays between calls.
See Account Levels & Rate Limits for tier details.
Output Quality Issues
Why is my output quality poor?
- Use Prompt Enhancer — It optimizes your prompt for better results ($0.001/use).
- Check model parameters — Resolution, steps, and other settings affect quality.
- Choose the right model — Different models excel at different tasks. Try a few to find the best fit.
- Provide clear prompts — Be specific and descriptive.
