Amazon Q · Rate Limits

Amazon Q Rate Limits

Amazon Q APIs (qbusiness, qdeveloper) follow standard AWS API throttling per account/region. Q Business agentic-request quotas and Q Developer agentic-request limits are tracked per user/subscription and surface as plan-level quotas rather than per-second throttles. AWS recommends exponential backoff with jitter on ThrottlingException.

Amazon Q Rate Limits is the machine-readable rate-limit profile for Amazon Q on the APIs.io network, in the API Commons Rate Limits shape.

It captures 5 rate-limit definitions, measuring varies, requests_per_second, requests_per_month, and lines_per_month.

Limit state is signalled in the requestId and retryAfter response headers, and an exhausted limit returns HTTP 400.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, and serviceUnavailable.

Tagged areas include Rate Limiting, GenAI, and Amazon Q.

Policies

Backoff with jitter
AWS SDKs default to standard retry mode (truncated exponential backoff with jitter, max 20s, 3 attempts).
Plan vs throttle quotas
Per-user agentic-request limits behave as monthly quotas; exceeding triggers a quota error rather than throttling.
Quota increases
Account-level API throttle limits are raisable via Service Quotas or AWS Support.
