Rate limits

When to use this page

Use this page to understand capacity protection and customer package behavior.

Limit layers

Quotaflow can enforce limits at multiple layers:

• Product capacity
• API key capacity
• Customer package limits
• Request queue limits
• Temporary usage limits

Dynamic capacity

Quotaflow estimates available capacity continuously. Temporary capacity changes may reduce the number of requests accepted until capacity recovers.

Queue behavior

When capacity is exhausted, eligible requests may wait in a bounded queue. If the queue is full or the wait exceeds the configured safe window, the request fails with a capacity error.

Retry guidance

• Retry 429 with exponential backoff and jitter.
• Retry 503 and timeouts.
• Do not retry authentication errors until the key is fixed.
• Keep session ids stable across retries.
