Same here, but my API key is still working on Typing Mind.

Yeah was getting a lot of it today. Switched some of my programming queries to Claude but just glad I’m not using it for a real service with users

I'm getting ridiculous amount of "overloaded_error" from Anthropic API recently. It has always been a problem, but in the last few days it is just ridiculous. For example, it has been happening non-stop for the last two hours.
The only way to use Anthropic models is through Amazon Bedrock, which doesn't have all the features that the native API has (especially the beta features). It's really disappointing. I'm often forced to use OpenAI, even though I find their model are worse for what I use them.

February 28, 2025 - Thank you ... You're right—this isn't a Zapier issue directly. The 529 Overloaded Error from Claude AI means that Anthropic's servers are under heavy load and rejecting or delaying requests.

r/Anthropic on Reddit: Impossibly too many API Error (529) overloaded_error

July 16, 2025 -

Anyone experiencing an "overload of overloads" in Claude Code? Today is the worst it's ever been. Literally over two dozens API Errors (529) in an hour. My buddy reports the same on his end. Is this because Kiro is using Sonnet, or what gives? Is Anthropic aware? I'm a paying customer of Claude Code, would love a working piece of software.

I have a feeling that Claude let AWS use their API in a full way and instead started rate limiting existing Claude users, lol, since we're already addicted to their product unlike the new AWS Kiro users

Same here—paying for the Max plan and I still can’t do anything today. I keep running into API errors. Seriously, what’s the point? .

November 5, 2024 -

I am facing the server overloaded error for 2 + hours now. Anyone else facing the same issue. I am using the sonnet 3.7 model. The api status is fine till now. So i don't know why its not working?

I feel that in the last month, I've been seeing more and more capacity issues when using the API. It's annoying as hell.
