Google Antigravity IDE

Google Antigravity IDE: 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.

See notes / depends on the protocol

This app has exceptions — read Notes below before pasting.

Quick way — command / config

# Antigravity IDE: no instructions for community patches / reverse proxies.
# To use a API Store Hub token with a coding agent, choose one of these apps:

1) Claude Code   → https://apistorehub.com
2) Cursor        → https://apistorehub.com/v1
3) Cline / Roo   → Anthropic custom base https://apistorehub.com
4) OpenClaw      → https://apistorehub.com

MCP in Antigravity (mcp_config.json) only adds TOOL — it does not replace the main model with API Store Hub.

Where to place file / fill Settings

Interfaceany

Agent sidebar → MCP (tuỳ chọn)

Configure MCP tools only if needed. Do not expect this to switch the core model to API Store Hub.

Verify connection

Install Claude Code or Cursor with a API Store Hub key and verify usage in Dashboard Usage.

Troubleshooting
