Error strings

• 429
• RESOURCE_EXHAUSTED

Situation

You create several API keys in one Google Cloud project to get more quota.

Symptom

429 RESOURCE_EXHAUSTED persists across keys.

Cause

Gemini rate limits are applied per project, not per API key, and daily request quotas reset at midnight Pacific time.

Fix

Plan quota per project and schedule bulk jobs around the Pacific midnight reset.

Snippet

# check usage per Google Cloud project, not per key

Verify

Compare your request rate with the limits shown for the project, and wait for the Pacific midnight reset for daily quotas.
