OpenAI-compatible
Chat completions, image generations, models, and health are available under https://chatgpt.authapi.dev/v1.
Hosted API · paired macOS bridge
Your ChatGPT app.
Available anywhere.
Pair your Mac once, then use the hosted playground or an OpenAI-compatible API client. The bridge keeps your authenticated ChatGPT session on your Mac and maintains an outbound encrypted relay connection.

A secure hosted surface
Use ChatGPT remotely without exposing your Mac to inbound network traffic or moving its desktop credentials to the server.
Outbound-only bridge
Your Mac connects outward over TLS and accepts only four typed operations. The hosted browser does not access your local network.
Credentials stay home
ChatGPT cookies, tokens, passwords, and desktop session data never leave your Mac.
Transient payloads
Prompts and responses transit authapi.dev in memory over TLS to your paired Mac and are not stored.
Named devices
Pair multiple Macs, see online and sign-in status, select a default, and revoke access instantly.
History cleanup
Text uses Temporary Chat. Image chats are deleted before Temporary Chat is restored.
Pair in under a minute
Requires the official ChatGPT macOS app, an active signed-in session, and Node.js 22 or newer.
1. Install bridge v11
Install or update the background bridge on your Mac. It validates a private download and restores the previous executable and service if installation fails.
set -eu umask 077 BIN="$HOME/.local/bin/chatgpt-api" mkdir -p "$HOME/.local/bin" TMP_DIR=$(mktemp -d "$HOME/.local/bin/.chatgpt-api-update.XXXXXX") TMP="$TMP_DIR/chatgpt-api.js" OLD="$TMP_DIR/previous" trap 'rm -rf "$TMP_DIR"' EXIT HUP INT TERM curl -fsSL https://chatgpt.authapi.dev/bridge.js -o "$TMP" node --check "$TMP" chmod 700 "$TMP" HAD_OLD=0 if [ -f "$BIN" ]; then HAD_OLD=1; cp -p "$BIN" "$OLD"; fi mv -f "$TMP" "$BIN" if ! "$BIN" install; then if [ "$HAD_OLD" = 1 ]; then cp -p "$OLD" "$BIN"; else rm -f "$BIN"; fi [ "$HAD_OLD" = 0 ] || "$BIN" install || true echo 'Bridge update failed; previous executable and service were restored.' >&2 exit 1 fi trap - EXIT HUP INT TERM
2. Create and paste a token
In Dashboard, name the Mac and create a 10-minute one-time token. Then run this command and paste the token at its hidden prompt:
~/.local/bin/chatgpt-api pair
Experimental and unofficial. This platform automates the official desktop UI and is not an OpenAI-supported ChatGPT API. Desktop app changes may require bridge updates.
