Cursor errors / Rate limit
User API Key Rate limit exceeded
Cause
Cursor relays the rate-limit from the upstream provider when a BYOK key exhausts its requests-per-minute or token quota, which Agent mode can hit quickly via parallel tool calls.
Fix
Wait for the provider's rate-limit window to reset (usually 60s). Check your tier's RPM/TPM limits on the provider dashboard. In Settings > Models, reduce Agent concurrency or switch to a higher-quota model. Upgrade the provider tier if Agent workloads routinely hit the cap.
