That's it.

**2 lines**.

And it has the same shape and structure that all your *path operation functions* have.

You can think of it as a *path operation function* without the "decorator" (without the `@app.get("/some-path")`).

And it can return anything you want.

In this case, this dependency expects:

  // The field is populated by the apiserver only if the
  // StorageVersionHash feature gate is enabled.
  // This field will remain optional even if it graduates.
  // +optional
  optional string storageVersionHash = 10;
}

// APIResourceList is a list of APIResource, it is used to expose the name of the
// resources supported in a specific group and version, and if the resource
// is namespaced.
message APIResourceList {

    ```

Let's focus on the parameters declared:

* Even though this function is a dependency ("dependable") itself, it also declares another dependency (it "depends" on something else).
    * It depends on the `query_extractor`, and assigns the value returned by it to the parameter `q`.
* It also declares an optional `last_query` cookie, as a `str`.

  * Not all "remote" repositories will fail. Specifically, if the remote
    repo uses the file:// protocol, and it doesn't refer to a shared
    filesystem, it will continue to be available.

  The question remaining is: Which level of offline mode will we support? It
  seems reasonable to assume that users will be able to tell when localhost is

To create the callback *path operation* use the same `APIRouter` you created above.

It should look just like a normal FastAPI *path operation*:

* It should probably have a declaration of the body it should receive, e.g. `body: InvoiceEvent`.
* And it could also have a declaration of the response it should return, e.g. `response_model=InvoiceEventReceived`.

The result of calling it is something that can be encoded with the Python standard <a href="https://docs.python.org/3/library/json.html#json.dumps" class="external-link" target="_blank">`json.dumps()`</a>.

It doesn't return a large `str` containing the data in JSON format (as a string). It returns a Python standard data structure (e.g. a `dict`) with values and sub-values that are all compatible with JSON.

 * The `java.net.URI` class is strict around what URLs it accepts. It rejects URLs like
 * `http://example.com/abc|def` because the `|` character is unsupported. This class is more
 * forgiving: it will automatically percent-encode the `|'` yielding `http://example.com/abc%7Cdef`.
