Codex CLI Responses API Base URL Setup

Codex CLI and Codex Desktop users often search for exact configuration phrases rather than broad AI terms. That makes Codex CLI base_url and Codex CLI Responses API useful niche keywords.

For AI Supermarket, Codex should use the OpenAI-compatible /v1 endpoint:

https://aisupermarket.work/v1

Example config.toml​

model_provider = "OpenAI"
model = "your-model"
review_model = "your-model"
model_reasoning_effort = "high"
disable_response_storage = true

[model_providers.OpenAI]
name = "OpenAI"
base_url = "https://aisupermarket.work/v1"
wire_api = "responses"
requires_openai_auth = true

Example auth.json​

{
  "OPENAI_API_KEY": "your-api-key"
}

Why wire_api = "responses" Matters​

Codex-style workflows often expect the Responses API rather than classic Chat Completions. If your client supports a wire_api field, set it to:

wire_api = "responses"

If you use a model or group that only supports Chat Completions, switch to a compatible group or use a client configuration that explicitly supports Chat Completions.

Debugging Checklist​

  • base_url includes /v1
  • wire_api is set to responses
  • the model exists in your Key group
  • auth.json contains the correct API Key
  • Codex Desktop or the IDE extension was restarted after config changes
