Google Antigravity CLI

Also known as: antigravity

Google Antigravity CLI: check the version and support for your own key and custom URLs before setup.

Published instructions · App version: unverified

Chat, ping, invoke and content-generation examples may send real billable requests. Check the model, balance, rate and minimum before running them. GET /v1/models checks authentication and the catalogue only. Set up environment variables safely

Base URL to paste

OpenAI SDKs generally use a URL ending in /v1; Anthropic SDKs use the root URL. Avoid adding /v1 twice. Protocol compatibility does not guarantee every provider feature.

Gemini-compatible (see notes)

This app has exceptions — read Notes below before pasting.

Prerequisites

Antigravity CLI is installed
Understand that the public ThAPI gateway is optimized for Anthropic + OpenAI

Recommended model: —

Quick way — command / config

# Antigravity CLI typically uses:
#   export GEMINI_API_KEY="..."
#   export GOOGLE_GEMINI_BASE_URL="https://…/gemini"
#   ~/.gemini/antigravity-cli/settings.json → modelProvider: "gemini"
#
# The public ThAPI currently primarily supports:
#   Anthropic  → https://thapi.cloud
#   OpenAI     → https://thapi.cloud/v1
#
# If you need Claude/GPT with a ThAPI token: use Claude Code, Cursor,
# OpenClaw, Cline or Codex — do not force Antigravity CLI to call /v1/messages.

Where to place file / fill Settings

Filemacos

~/.gemini/antigravity-cli/settings.json

Only change this after Gemini-compatible provider support has been confirmed with ThAPI. Default: switch to Claude Code/Cursor.

Filelinux

~/.gemini/antigravity-cli/settings.json

Same as macOS.

Filewindows

%USERPROFILE%\.gemini\antigravity-cli\settings.json

Same as macOS.

Verify connection

If you only have a ThAPI token, configure Claude Code or Cursor using its guide, then test a chat.
Do not expect Antigravity CLI to charge the ThAPI wallet unless ThAPI announces a Gemini endpoint.

Troubleshooting

Symptom	Reason	How to handle
404 / model_not_available when pointing to thapi.cloud/v1	Antigravity CLI does not use plain OpenAI Chat Completions.	Switch to Claude Code / Cursor / Cline with the same ThAPI key.
