API Error: Request rejected (429) · this may be a temporary capacity issue. If it persists, check https://status.claude.com.Status: By designLast verified 3 documented fixes2 sources
What it means
You have hit the rate limit configured for your API key, Amazon Bedrock project, or Google Cloud project. This is distinct from the server-side throttle API Error: Server is temporarily limiting requests (not your usage limit).
Causes
- The rate limit tier on your API key or cloud project
- A stray ANTHROPIC_API_KEY routing requests through a low-tier key instead of your subscription
- High concurrency from many parallel subagents or tool calls
How to fix it
- Fix 1.
Run /status and confirm the active credential is the one you expect.
Slash command/status - Fix 2.
Check your provider console for active limits and request a higher tier if needed.
- Fix 3.
Reduce concurrency: lower CLAUDE_CODE_MAX_TOOL_USE_CONCURRENCY, avoid running many parallel subagents, or switch to a smaller model with /model for high-volume scripted runs.
