Fireworks AI 402 "Account is not on a paid plan or has exceeded usage limits"

What does the error mean?

Fireworks’ error codes page lists 402 Payment Required with the cause Account is not on a paid plan or has exceeded usage limits. A related code, 412 Precondition Failed, covers a suspended account or a problem with account status.

There are two common triggers. Your balance can reach zero with Auto Reload off, in which case usage pauses until you add credits. Or your usage can reach 100% of the monthly spend limit. Then every API request pauses across serverless inference, deployments and training, even with credits left.

How do you fix it?

1. Open Billing and check the credit balance and the monthly spend limit.
2. If the balance is empty, add credits.
3. If you’re at the spend limit, raise it. Adding credits doesn’t. From the CLI, firectl quota list shows the limit and firectl quota update monthly-spend-usd --value 200 sets it to $200.
4. If a payment failed, fix the payment method and add credits, or pay outstanding invoices on a postpaid account. The account reactivates on its own within an hour.
5. If you only ever had the $1 starter credit, add a payment method. Without one, the account stays suspended once that credit is gone.

Contact inquiries@fireworks.ai if none of that clears it.

How do you keep it from coming back?

Turn on Auto Reload so credits are bought when the balance reaches the minimum you set. Then set the monthly spend limit above your real peak month, because Auto Reload doesn’t change how much usage the limit allows.

Fireworks emails a warning at 80% of the spend limit by default. Add earlier thresholds from the Billing page, or with firectl billing notification-settings update --monthly-spend-usd-thresholds=500,800.

With no payment method or no credits, the account is also held to 10 requests per minute instead of 6,000. A card that keeps paying keeps you on the higher limit. ernd is a card for AI spend that earns 4% back on AI vendor bills.
