Claude API 529 Error vs 429: Causes, Retries, and Production Recovery
A Claude API 529 error and a 429 error can look almost identical inside an application: the request fails, the user waits, and a retry may work. But they describe different failure modes. A 529 response means the Claude API is temporarily overloaded across users, while a 429 response normally means your organization has exceeded…
