How to fix Claude API error 500?

Many users appeared to be getting an API error 500.

"Claude Down?? API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id":"req_011CZ9EZWq6y5UfubJ1t2v9M"}", one person wrote on X.

An API 500 error means there is an internal server error on the Anthropic side meaning there is no fix on the user side which is possible. It is usually triggered by transient issue, an outage, or a problem with the configuration of the request.

Claude or Anthropic are yet to release a statement about the outage. The cause for the outage also remains unknown.

Currently, the number of complaints appear to have sharply fallen to a little over 1,000 in the US. However, the outage appeared to be global with people from other countries complaining about the same error.

"Claude Code - UK not sure about others - anyone else getting API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id": etc. on all sessions?," one person asked on X.

Another wrote in Japanese on X “Since Claudecode-kun is down with a Claude Code API Error: 500, guess I'll hop in the bath too,” as per the translation.
