PSA: API Credits expire after one year

I just got a mail that my access to Anthropic API has been disabled because I ran out of credits, even though I have not used the API in a year. At first, I thought I got hacked, but apparently, credits just expire.

The fact that credits expire is hidden on a separate "Supplemental Credit Terms" page, which is different from the "Commercial Terms of Service" page, which is again different from the regular "Consumer Terms of Service" page.

I found that kind of information hiding a bit shady, but apparently, this is common among API providers. I still feel robbed and will think hard before buying more credits in the future.
