 - `--port <PORT>`: Port to bind on `127.0.0.1`. If omitted, an ephemeral port is chosen.
 - `--server-info <FILE>`: If set, the proxy writes a single line of JSON with `{ "port": <PORT>, "pid": <PID> }` once listening.
 - `--http-shutdown`: If set, enables `GET /shutdown` to exit the process with code `0`.
+- `--upstream-url <URL>`: Absolute URL to forward requests to. Defaults to `https://api.openai.com/v1/responses`.
+- Authentication is fixed to `Authorization: Bearer <key>` to match the Codex CLI expectations.
+
+For Azure, for example (ensure your deployment accepts `Authorization: Bearer <key>`):
+
+```shell
+printenv AZURE_OPENAI_API_KEY | env -u AZURE_OPENAI_API_KEY codex-responses-api-proxy \
+  --http-shutdown \

 Care is taken to restrict access/copying to the value of `OPENAI_API_KEY` retained in memory:
 
 - We leverage [`codex_process_hardening`](https://github.com/openai/codex/blob/main/codex-rs/process-hardening/README.md) so `codex-responses-api-proxy` is run with standard process-hardening techniques.
-- At startup, we allocate a `1024` byte buffer on the stack and write `"Bearer "` as the first `7` bytes.
+- At startup, we allocate a `1024` byte buffer on the stack and copy `"Bearer "` into the start of the buffer.
 - We then read from `stdin`, copying the contents into the buffer after `"Bearer "`.
 - After verifying the key matches `/^[a-zA-Z0-9_-]+$/` (and does not exceed the buffer), we create a `String` from that buffer (so the data is now on the heap).
 - We zero out the stack-allocated buffer using https://crates.io/crates/zeroize so it is not optimized away by the compiler.
