To qualify for Tier 2, you'll need to purchase a cumulative total of $40 of API usage credits on your Console account. Here's what you need to do:
1. Log into your Console account (console.anthropic.com)
2. Go to the Billing page
3. Add $40 in usage credits to your balance, either through a single purchase or multiple purchases totaling $40
After making this purchase, your account will automatically upgrade to Tier 2, increasing your monthly usage limit to $500. You're not allowed to deposit more than your monthly spend limit, which helps minimize the risk of overfunding your account.
See our API docs for more information about rate limits and usage tiers.
