Is it safe to use Antigravity subscription accounts via the local API Proxy for OpenClaw agent loops?

[Gilsz]

Hi, I’m considering using Antigravity Manager specifically to route my Antigravity subscription accounts (not Gemini/Vertex API keys) through the local API Proxy (http://127.0.0.1:8045/v1) so that I can use them with OpenClaw for autonomous agent workflows (long‑running loops, tool use, multi‑turn reasoning).

My current understanding:

• Antigravity Manager’s proxy exposes OpenAI‑compatible endpoints and can use Antigravity accounts as upstream providers.
• Google’s Antigravity Additional Terms (Section 6) explicitly forbid “using the Service in connection with products not provided by us,” and there have been mass bans since February 2026 for users who connected OpenClaw directly to Antigravity via OAuth.
• Those bans appear to target the pattern of using Antigravity’s IDE/CLI subscription backend to power a third‑party tool, regardless of whether a local proxy is involved.

Given that, I need a very direct answer:

1. Is it safe (in terms of Google enforcement / account bans) to use Antigravity subscription accounts through Antigravity Manager’s local API Proxy with OpenClaw for autonomous agent loops?

   • If yes: what specific configuration do you recommend to minimize risk (e.g., rate limits, jitter, account rotation, model choices)?
   • If no or “unknown”: please say so explicitly.

2. If the answer to (1) is “no” or “high risk,” what is the intended use case for the proxy?

   • Is it only meant for official API keys (Gemini Dev API / Vertex AI / Anthropic / OpenAI)?
   • Or is there any scenario where using Antigravity subscription accounts behind the proxy is considered acceptable?

3. Do you personally use Antigravity subscription accounts behind the proxy with OpenClaw or similar tools?

   • If yes, have you or your users experienced any “Account not eligible” / 403 ToS bans on those accounts?
   • If no, why not?

I’m trying to decide whether to proceed with this setup or avoid it entirely. I’d prefer a blunt, realistic answer over optimism. If the honest answer is “this is high‑risk and you should not do it with accounts you care about,” that’s perfectly fine and actually very helpful.

Thanks in advance for your time and clarity.

Hi there, thanks for laying out all the context clearly. I’ll give you straight, non‑optimistic answers point‑by‑point. These are real‑world operational observations only and do not constitute legal advice.

1. Is it safe (in terms of Google enforcement / account bans) to use Antigravity subscription accounts through Antigravity Manager’s local API Proxy with OpenClaw for autonomous agent loops?
   Answer: High risk. There is no guarantee against account bans; you should not run this setup on subscription accounts you cannot afford to lose.

The local proxy (127.0.0.1:8045/v1) only rewrites and forwards traffic locally. It cannot hide usage patterns from Google backend telemetry. Google can detect request signatures: long‑running autonomous loops, heavy tool‑call bursts, high‑volume multi‑turn reasoning — these are exactly the trigger patterns behind the mass bans starting February 2026. This holds true whether traffic goes directly via OAuth or passes through this local proxy.

Rate‑limits, jitter, account rotation or model tweaks inside Antigravity Manager can only reduce the chance of an immediate ban. They cannot eliminate the ToS violation risk under Additional Terms Section 6. No configuration can make this setup truly “safe”.

2. If the answer to (1) is “no” or “high risk,” what is the intended use case for the proxy?
   Currently the proxy mainly supports opencode and self‑hosted API reverse‑proxy scenarios. Some projects want Gemini capabilities but prefer not to pay for official Gemini API keys, and leverage the proxy for that purpose.

Even so, routing Antigravity subscription accounts behind the proxy for external autonomous agent tools like OpenClaw is still not an officially supported workflow. The proxy is purely a protocol translation layer; it does not override Google’s terms of service.

3. Do you personally use Antigravity subscription accounts behind the proxy with OpenClaw or similar tools?
   I do not run long‑lived autonomous agent loops such as OpenClaw against my accounts.

I maintain roughly 5 Google accounts. I have not encountered bans under regular opencode usage. However, this does not guarantee you will see the same outcome. Ban outcomes depend entirely on Google’s dynamic internal risk‑control algorithm.

Some users in the project community have experimented with agent workloads via the proxy, and a subset of them received Account not eligible and 403 ToS‑enforced bans consistent with the reports you referenced. That is why I avoid running these high‑risk workloads on my own accounts.

Final note: If you value your Antigravity subscription accounts, you are strongly advised to avoid this setup entirely.
