codex-api-tool

A lightweight local proxy + GUI for Codex-compatible Responses API routing.

What it does

• Runs a local proxy server.
• Lets you create multiple model rewrite rules in GUI.
• Each rule is exact-match:
  • If incoming model == source model, rewrite to target model.
  • If no rule matches, request is forwarded unchanged.
• Splits logs into two pages:
  • Event Log: startup/shutdown/config/rule/error + request summary
  • Request Log: per-request timestamp, source model, final model, matched rule, status

Example

Rule:

• Source: gpt-5.3-codex
• Target: gpt-5.3-codex-xhigh

Result:

• Incoming gpt-5.3-codex -> rewritten to gpt-5.3-codex-xhigh
• Incoming gpt-5.5 -> unchanged

Run

python rightcode_proxy_gui.py

Then set your Codex/ccswitch provider base_url to:

http://127.0.0.1:8787/codex/v1

Build EXE

python -m pip install pyinstaller
python -m PyInstaller --noconfirm --clean --onefile --windowed --name rightcode-proxy-gui rightcode_proxy_gui.py

Output:

• dist/rightcode-proxy-gui.exe

Generated files

• rightcode_proxy_config.json
• rightcode_proxy_events.jsonl
• rightcode_proxy_requests.jsonl

Notes

• Authorization headers are forwarded to your configured upstream.
• Rules are order-sensitive; first exact match wins.
