This PR introduces a new, optional input to the GitHub Action,
`responses-api-endpoint`, which makes it possible to use this Action
with Azure. As explained in the updated `README.md`, if
`responses-api-endpoint` is specified, it will be the URL that Codex
hits to make Responses API requests. In practice, we expect this to be
used mostly by Azure users.
With the Azure account I just created, I got this working with the
following configuration:
```yaml
jobs:
codex:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v5
- name: Start Codex proxy
uses: openai/codex-action@71690bb0c5
with:
openai-api-key: ${{ secrets.AZURE_OPENAI_API_KEY }}
responses-api-endpoint: "https://bolinfest-7804-resource.cognitiveservices.azure.com/openai/v1/responses"
```
Under the hood, if `responses-api-endpoint` is non-empty, it simply
becomes the `--upstream-url` argument to `codex-responses-api-proxy`.
TO DISCUSS: Better/shorter name than `responses-api-endpoint`?
This PR builds on the work of https://github.com/openai/codex/pull/6129.
