Anthropic experienced an issue on September 1, 2026, where users purchasing credits for the Claude API encountered delays in credit availability. This led to some API requests erroneously showing 'credit balance is too low' errors. The problem specifically affected credits bought between 05:10 AM PT and 2:35 PM PT on that day. Anthropic has since resolved the core issue, and purchased credits should now be available as expected, though they are working to address any lingering impacts. AI
IMPACT Minor disruption for Claude API users, with prompt resolution expected.
