Console tip: set quotas per API key

A quick console feature worth knowing about: every API key can carry its own monthly spend quota. When a key hits its cap, requests fail fast with a clear 429 instead of quietly burning your balance.

This is the safest way to hand keys to side projects, coding agents, or teammates — set a small quota first, raise it when trust is earned.

Quotas, usage history and key rotation all live in the console. Log in and check the Keys section to try it.
