Handling insufficient balance, insufficient quota, and no permission
This is the most common reason you "have quota but can't use it." First work out which kind of "not enough" it is.
Differences between the three kinds of "insufficient"
| Symptom | What it really is | Error signature |
|---|---|---|
| Insufficient balance | The account's "money" has run out | insufficient balance / 429 |
| Insufficient subscription quota | The plan quota is used up (daily/weekly/monthly) | Quota exceeded notice |
| No permission | The group/model isn't open to you | 403 |
Insufficient balance
- Check the balance on your dashboard and confirm whether it is 0 or too low
- Top up (Top-up) or redeem (Redemption code)
- Turn on Balance alerts so you don't get cut off unexpectedly
TIP
When an OpenAI-family channel is short on quota, it returns the standard insufficient quota error format. This may mean the channel account's own quota is used up rather than a problem with your balance — retry later or contact support (support@kuaiapi.net).
Insufficient subscription quota
- Check the "Subscription" page: remaining quota, reset time
- Daily/weekly cards reset daily/weekly, just wait for the reset
- Need more → upgrade your plan or stack subscriptions
No permission (403)
- The group bound to the key does not include that model
- The group is "Exclusive" and you are not authorized for it
- The site has disabled that group/model
Solution: switch to an available model, or contact support (support@kuaiapi.net) to get access.
