Tip: making a prediction and getting a result requires two `curl` requests: a `POST` and a `GET`. The `POST` request returns an `EVENT_ID` and prints it to the console , which is used in the second `GET` request to fetch the results. We'll cover these two steps in more detail in the Guide below.
Note: making a prediction and getting a result requires two `curl` requests: a `POST` and a `GET`. The `POST` request returns an `EVENT_ID` and prints it to the console, which is used in the second `GET` request to fetch the results. You can combine these into a single command using `awk` and `read` to parse the results of the first command and pipe into the second, like this:

```bash
$ curl -X POST https://abidlabs-en2fr.hf.space/call/predict -H "Content-Type: application/json" -d '{
"data": ["Hello, my friend."]
}' \
| awk -F'"' '{ print $4}' \
| read EVENT_ID; curl -N https://abidlabs-en2fr.hf.space/call/predict/$EVENT_ID

>> event: complete
>> data: ["Bonjour, mon ami."]
```

In the rest of this Guide, we'll explain these two steps in more detail and provide additional examples of querying Gradio apps with `curl`.


**Prerequisites**: For this Guide, you do _not_ need to know the `gradio` library in great detail. However, it is helpful to have general familiarity with Gradio's concepts of input and output components.

When you make this `POST` request successfully, you will get an event id that is printed to the terminal in this format:

```bash

This `EVENT_ID` will be needed in the subsequent `curl` request to fetch the results of the prediction.
