Setup guides

Set up your RocketKey API key in Claude Code, Codex, Cline and Cursor. Every snippet uses the placeholder key sk-rk-YOUR_KEY_HERE: replace it with your key.

Getting startedBuy a monthly plan with VietQR, get your RocketKey API key and test it with one curl command before setting up Claude Code, Codex, Cline or Cursor.
Claude CodeConfigure Claude Code with a RocketKey API key: ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN for bash, PowerShell, CMD, settings.json and VS Code.
CodexAdd the RocketKey provider to ~/.codex/config.toml (wire_api responses) and set ROCKETKEY_API_KEY so Codex CLI uses your RocketKey monthly plan.
ClineConfigure Cline in VS Code with a RocketKey API key: pick the OpenAI Compatible provider, then enter the base URL, key and model ID.
CursorUse a RocketKey API key in Cursor via Override OpenAI Base URL: setup, which models work and the limits (chat and agent only, not Tab).
