[BUG] Rate limit even though I should not be

[kiikoh]

Bug Description
Plugin stopped working for me entirely. Getting rate limit errors even though I can use antigravity editor fine. Logged on tonight and was able to send one query, then started getting rate limit errors.

To rule things out:

• Only use single account
• Able to use the antigravity editor directly (it sucks!)
• Using the vscode extension @tctinh made I can still see I have plenty of rate limit however I get the rate limit error toast.
• This happens with both opus and gemini models.
• My google account should have fairly high rep if that matters (10 yr+ account) paying for various other google services (but not ai pro)

Compliance Checklist
Please confirm:

• I'm using this plugin for personal development only
• I have an active Google Cloud project with Antigravity enabled
• This issue is not related to attempting commercial use or TOS violations
• I've reviewed the README troubleshooting section

Additional Context
This plugin normally works fine for me, so not sure what happened, could google have changed something?

I'm having the same exact issue, but I am paying for Google One AI pro account

Same here on my end. Also i can verify that antigravity itself is not rate limiting.

[faiz-gear]

For me, only flash model is working

[carlesoctav]

o7

[archodev]

Same, did Google block the plugin?

[dimx9173]

I'm experiencing the same issue, but my antigravity IDE is still functioning.

[PhucTruong-ctrl]

same for me

[Internal-Tide]

Same for me!
But models from gemini cli is normal!

[BGuimberteau]

Same here

[OptionalCoin]

damn I thought I was going nuts trying to figure this out why this was not working with my 2 pro accounts

[motonari728]

Is Google detecting plugin now? Holy shit.
I paid yearly pro account.

[royisme]

I think the reason is that this request method has been detected and blocked by Google, and currently only requests made through the antigravity IDE work normally.

similar issue occurs to all reverse proxy of antigravity:

CLIProxyAPI is same. Global problem.
