[Bug] Anthropic API Credential Restriction Preventing API Requests

started this morning

same here
Windows VSCode
Using Claude Code
> claude doctor
⎿ API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"This credential
is only authorized for use with Claude Code and cannot be used for other API
requests."},"request_id":"req_011CTQxWurzPBesaHzT67FW6"}
UPD: relogin helped

I've tried running claude setup-token again and the issue still persists. Started this morning for me too.

Yes, I see the same error. Yesterday it worked fine.

I see this error (Mac VSCode, using claude code)

Seems to be affecting zed through ACP too.

My experience is that when Claude fixed Claude App and API connectivity errors, certain users are required to re-anthentic their account but the API error didn't prompt that. The workaround is to run claude /login

This worked for me. Just re-login.

Yes, work for me too with re-login.

Not for me. After Re-Login it's the same

Still failing after claude setup-token

still failing after re-login here, but I still had an export for an existing CLAUDE_CODE_OAUTH_TOKEN. Once I removed that export and tried "claude /login" it worked for me.

Also affects the Claude GitHub integration for PR reviews

Hi, also fixed with claude /login, thanks

Also having the problem seems today with OpCode (name was 'Claudia' before), re-logged in without any better result.
It seems I can still use Claude Code by selecting Claude Sonnet 4 but not anymore using Claude Opus 4.1 where I do have this error 400.

Confirming claude /login fixes this problem for me in Claude Code.

Hi, Confirming as well that claude /logout and then claude /login fixes in Claude Code.

I can confirm that logging out and then back in (claude /logout and then claude /login) resolved the issue.
By the way, before it was fixed, I had access to Opus 4.1 despite being only on the Pro plan. Now back to normal.

I found the cause of the problem, because after the claude code update, the recommended configuration was updated, but this recommended configuration is not applicable to Pro subscribers.
You can use the /model command to see the model currently used by Claude Code, which will output:

│  Select Model                                                                │
│  Switch between Claude models. Applies to this session and future Claude     │
│  Code sessions. For custom model names, specify with --model.                │
│                                                                              │
│     1. Default (recommended)   Opus 4.1 for up to 50% of usage limits,       │
│                                then use Sonnet 4                             │
│     2. Opus                    Opus 4.1 for complex tasks · Reaches usage    │
│                                limits faster                                 │
│   ❯ 3. Sonnet                  Sonnet 4 for daily use ✔                      │
│     4. Opus Plan Mode          Use Opus 4.1 in plan mode, Sonnet 4           │
│                                otherwise

The default configuration uses the Opus 4.1 model, which is not available for the pro subscription, which is also the root cause of the error.
Select "3. Sonnet", problem solving.

@zorth44 Thank you, this works! So it's only a problem for Pro users.

Thanks to @zorth44's comment, it's now also clear how to fix the GitHub code review workflow: The default setting now also appears to try to use the Opus model. So Pro users need to explicitly ask for Sonnet in claude-code-review.yml:
claude_args: '--model sonnet --allowed-tools "Bash(gh issue view:*),Bash(gh search:*),Bash(gh issue list:*),Bash(gh pr comment:*),Bash(gh pr diff:*),Bash(gh pr view:*),Bash(gh pr list:*)"'

Also affects the Claude GitHub integration for PR reviews

This issue also affects the Claude GitHub integration for PR reviews. Previously, it automatically used claude-opus-4-1-20250805 model and even worked with Pro accounts.

Here is what I've found in Claude Code Preview logs with a Pro account showing the mixed model usage:

"modelUsage": {
  "claude-3-5-haiku-20241022": {
    "inputTokens": 2303,
    "outputTokens": 180,
    "cacheReadInputTokens": 0,
    "cacheCreationInputTokens": 0,
    "webSearchRequests": 0,
    "costUSD": 0.0025624000000000003
  },
  "claude-opus-4-1-20250805": {
    "inputTokens": 41,
    "outputTokens": 1297,
    "cacheReadInputTokens": 139599,
    "cacheCreationInputTokens": 8747,
    "webSearchRequests": 0,
    "costUSD": 0.47129475
  }
}

for the recently released sonnet 4.5, use this instruction to fix it.
Tell this to your Claude Code or Codex Cloud

---

1. Open .github/workflows/claude.yml. In the Run Claude Code step, set claude_args to --model claude-sonnet-4-5-20250929, preserving every other setting in the workflow.
2. Open .github/workflows/claude-code-review.yml. In the Run Claude Code Review step, update the claude_args string so it starts with --model claude-sonnet-4-5-20250929 while leaving the quoted --allowed-tools list untouched.
3. Save both workflow files, commit with a message such as Add model argument to Claude workflows, and push the branch.
4. Open a PR describing that the general and review Claude workflows now request the Sonnet 4.5 model.

IT STILL OCCURS

Just got this now in opencode

@GukDev lmao me too

same

same

I'm having it now in opencode

I just ran into this on opencode as well — logging out and back in had no effect, the problem keeps happening

Same here: Opencode and tried to re-login. I hope they're not forcing us to just use claudeCode.

Time to code a work around in CC with Opus to get CC sub working in OpenCode again!

we are going back to September 23 2025, instead of moving forward lol

Also just got this issue

We got back in time. Isn't it guys?

just got bombed out as well. Not sure how to get it to work again. sigh.

Also Opencode. I just renewed my subscription a few hours ago. This just interrupted my work. If they really start restricting to use other tools WITHOUT ANY ANNOUNCEMENT, I'm out.

We got back in time. Isn't it guys?

"Ich bin du, Jonas"

Just got this in opencode as well.

looks like im not the only one

got the same issue

Same issue.

Got it using clawdbot. Hope I can clear it.

Fuck I got the same issue

me too, why does it matter what harness??? didn't we pay for the compute?

Same here

Getting this issue on RooCode as well, using Claude Code as the API Provider / Even with 0Auth Sign-in / Still getting this Error

I'm experiencing this issue as well.

Same here

Same issue here. Re-auth with opencode or claude code does not work.

Same. So frustrating.

anthropic want everyone to open CC and allow data sharing for improving their models 💀

Bro I just got on this bandwagon today, what the helly

Anyone with an academic .edu license might be able to get github copilot for free, so I was able to spin up Claude 4.5 via my github copilot auth within OpenCode. However, my main Claude subscription no longer authenticates in OpenCode.

Just got this in opencode as well, on a claude max subscription.

the same here in opencode... are we gonna get forced to use Claude code or are they gonna try to sneak an upsell in our subscriptions?

I'm having the same issue too, only in opencode though, everything's fine in claude code cli. tried logging in again but it didn't help

Getting this too! That is not cool at all for $200 a month

anyone found a fix yet?

It looks like there are a few comments from the last few hours. I also have an expensive subscription. Seems like Opencode is logging in fine, but using the token doesn't work

same here stoped working with open code

I forgot how to code, fix this or I'll be fired.

Hitting this too. It's a real shame too - I got a ton of appreciation of my subscription and it's price from being able to use my subscription in the way that best suited me.

please fix this. was perfectly fine yesterday. also using opencode with a claude max subscription.

Same issue here. Saw this error when i tried it with OpenCode.

same issue here with opencode

Pinging just so i know when its resolved

Same issue with opencode, yesterday it was working in opencode, today its not

glad I'm not the only one... was freaking out... better get this fixed or I'll look for a job at Walmart or something similar

The chiringuito is over https://github.com/charmbracelet/crush/pull/1783

Just as I figured. They are blocking 3rd party clients and instead of just outright announcing it, you have to FA&FO. Nice!

Just saying ping or commenting is only making this thread difficult to read.. there is a possible solution by using https://github.com/anomalyco/opencode-anthropic-auth as referenced from @n2k3 solution ->

Fuck, their patch it

https://github.com/anthropics/claude-code/issues/17118

My workaround:

Step 1:
https://claude.ai/new , click on profile picture (bottom left corner), "Request help", request a refund via their chatbot (I used the reason "other"). For me it worked, they already confirmed the refund.

Step 2:
Subscribe to Minimax and GLM, accept slightly lower quality but at the same time be safe from stuff like that happening again (without prior warning, and THAT is what really annoys me about the situation) because the models are open and cheap so you can just switch providers if necessary. And btw this also saves you a lot of money and I've never managed to even get close to their limits while even with the most expensive Claude Max subscription I had to slow down multiple times.

Step 3:
Watch Anthropic go down because they overestimated the value of their ecosystem and how much developers hate to be locked into a closed system.

VERY interesting how it suddenly does not work anymore after people have been stating they were migrating to OpenCode because Anthropic refuses to fix this recurrent showstopping bug

"how much developers hate to be locked into a closed system."

😂🤣😂🤣 laughs at how large the iOS dev scene is

Same problem - very upsetting.

Just became a user yesterday and it worked great, now - I'm here 🙃

Yup, got this today as well. Worked for me until yesterday. Smells very bad to lock people in to their apps – who else have I hated on over the decades for this same behavior, let me think… Oh yes.
