Claude API pricing — is it not a monthly subscription, just pay-as-you-go?

Hi there, admin here. To cut to the chase: Claude API works on a prepaid credit system, just like ChatGPT API. You buy credits upfront and your API calls are deducted from that balance—not post-paid billing. Let me break down how it works. 1. Billing model: According to the official help center (support.claude.com), "API and Workbench usage is billed against prepaid credits, and you must purchase credits before making any API calls." Once your balance hits zero, API calls stop working. 2. How to add credits: Go to console.anthropic.com, navigate to Settings > Plans & Billing, and pay for whatever amount you need. There's no cap—you can add as much as you want. 3. Auto-reload (optional): In your Console billing settings, you can turn on auto-reload so that when your balance drops below a threshold you set, it automatically recharges by a fixed amount. This is totally optional; turn it off and your credits just deplete over time. 4. Credit expiration: Credits expire 1 year from purchase and can't be extended. No refunds either, so I'd recommend starting with a small amount like $5–$10 to test things out. 5. Relationship to Claude.ai Pro/Max: Claude.ai subscriptions (Pro/Max) and API billing are completely separate. Even if you have a Pro subscription, you still need to separately charge API credits in the console to use the API. You can use just the API, just Claude.ai, or both. 6. No surprise charges: Because it's prepaid, you can never be billed more than what you've charged. As long as you don't enable auto-reload, you won't go over—which actually makes it safer for people getting started. Start with $5–$10 and go from there.
