# Sandbox Mode

You can make up to 1,000 free calls by month to the Image Editing API using sandbox mode (100 max per day).

Sandbox mode is meant to be used for testing and prototyping, and will produce an image with a watermark.

To use sandbox mode, prepend `sandbox_` to your API key. (Example: `sandbox_xxxxxxxxxxxxxxxx`)

```bash
curl --request POST \
  --url https://sdk.photoroom.com/v1/segment \
  --header 'x-api-key: sandbox_xxxxxxxxxxxxxxxx' \
  --form image_file=@/path/to/image.jpg \
  --output result-sandbox-mode.png
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.photoroom.com/remove-background-api-basic-plan/sandbox-mode.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
