# Questions and Answers
## For how long will my files be stored?
Files will be removed if they have not been viewed for 30 days. A view is
counted when someone visits the file's download page (pixeldrain.com/u/somefile)
or views the file through a list the file is included in
(pixeldrain.com/l/somelist).
If you upload a file while logged into your pixeldrain account you will be able
to delete the file yourself from the download page of the file. If you are not
logged in and you accidentally upload something you shouldn't have, just don't
share the link. The file will expire eventually. File links are not indexed or
published anywhere. As long as you don't share it nobody will see it.
## Does pixeldrain cost any money?
No, pixeldrain is completely free at the moment. While there is an advertisement
on the file downloading page, it doesn't generate nearly enough revenue to pay
for maintaining this service. That's why I'd really appreciate it if you could
spare some coins. Possible methods for donating are:

## Do I need to register an account?
Not if you don't want to. You're free to use pixeldrain completely anonymously.
Without a pixeldrain account you can upload files, download files and create
lists of files. And view your uploaded files on the [history page](/history).
This page only shows files which were uploaded anonymously in this web browser.
By registering an account on pixeldrain you will be able to access your files
from any device with a web browser. Files you upload and lists you create will
be linked to your pixeldrain account and will show up on your [personal home
page](/user).
## What cookies does pixeldrain use?
When logging in to a pixeldrain account a cookie named 'pd_auth_key' will be
installed. This cookie keeps your login session active. When you delete it you
will be logged out of your account.
When you use the style selector on the [Appearance](/appearance) page a cookie
called 'style' will be set. This cookie controls the appearance of the website
for you.
When uploading a file pixeldrain will save a list of file links on your
browser's local storage. This data is **only** used for viewing your upload
history on the [history page](/history).
## Legality
I cannot be held liable for any illegal and / or copyrighted material that's
uploaded by the users of this application. Files uploaded to this website are
subjected to local laws. If laws are being broken, and I've been notified of the
fact I'll have to delete the offending content. If you find any files on this
domain that break the law, please contact me at
[abuse@pixeldrain.com](mailto:abuse@pixeldrain.com), and I'll take care of it.
Please share responsibly.

# Pixeldrain API documentation
The methods for uploading and retrieving files don't require an API key. The
methods for creating and retrieving lists also don't require an API key. All
methods which delete or modify a resource **do** require an API key.
API keys can be obtained from the login API.
Some JSON responses include fields which end in "_href" (some people don't know
this, but "href" stands for "Hypertext Reference", the more you know). These
point to different places in the API, which you can retrieve with a GET request.
The path is to be appended to the API URL, so "/file/someid/thumbnail" becomes
"{{apiUrl}}/file/someid/thumbnail".
The base URL for the API is "{{apiUrl}}", all paths below are relative to that
URL.
## Form value order
I recommend you put files at the end of every file upload form. By doing this
the pixeldrain server can respond to malformed requests before the file upload
finishes and this may save you a lot of time and bandwidth when uploading large
files. Make sure your HTTP client has support for premature responses,
pixeldrain uses them a lot. If the server responds before your request is
finished it will always indicate an error and you may abort the connection.
## File Methods
<details class="request_post">
<summary><span class="method">POST</span>/file</summary>
<div>
### Description
Upload a file.
### Parameters
Param | Type | Required | Maximum Size | Default | Description
----------|----------------|----------|----------------|---------------------|-----------------------------------

"success": true,
"id": "abc123" // ID of the newly uploaded file
}
```
HTTP 422: Unprocessable Entity
```
{
"success": false,
"value": "no_file",
"message": "The file does not exist or is empty."
}
```
HTTP 500: Internal Server Error
```
{
"success": false,
"value": "internal",
"message": "An internal server error occurred."
}
```
HTTP 413: Payload Too Large
```

</div>
</details>
<details class="api_doc_details request_get">
<summary><span class="method">GET</span>/file/{id}</summary>
<div>
### Description
Returns the full file associated with the ID. Supports byte range requests.
When '?download' is added to the URL the server will send an attachment header
instead of inline rendering, which causes the browser to show a 'Save File'
dialog.
Warning: If a file is using too much bandwidth it can be rate limited. The rate
limit will be enabled if a file has ten times more downloads than views. The
owner of a file can always download it. When a file is rate limited the user
will need to fill out a captcha in order to continue downloading the file. The
captcha will only appear on the file viewer page (pixeldrain.com/u/{id}). Rate
limiting has been added to prevent the spread of viruses and to stop direct
linking.
Pixeldrain also includes a virus scanner. If a virus has been detected in a file
the user will also have to fill in a captcha to download it.
### Parameters
Param | Required | Location | Description
---------|----------|----------|------------------------------------------
id | true | URL | ID of the file to request
download | false | URL | Sends attachment header instead of inline
### Returns

<h1>About pixeldrain</h1>
<div class="page_content"><div class="limit_width">
<h2>Questions and Answers</h2>
<h3>For how long will my files be stored?</h3>
<p>
Files will be removed if they have not been viewed for 30 days.
A view is counted when someone visits the file's download page
(pixeldrain.com/u/somefile) or views the file through a list the
file is included in (pixeldrain.com/l/somelist).
</p>
<p>
If you upload a file while logged into your pixeldrain account
you will be able to delete the file yourself from the download
page of the file. If you are not logged in and you accidentally
upload something you shouldn't have, just don't share the link.
The file will expire eventually. File links are not indexed or
published anywhere. As long as you don't share it nobody will
see it.
</p>
<h3>Does pixeldrain cost any money?</h3>
<p>
No, pixeldrain is completely free at the moment. While there is
an advertisement on the file downloading page, it doesn't
generate nearly enough revenue to pay for maintaining this

<h3>Do I need to register an account?</h3>
<p>
Not if you don't want to. You're free to use pixeldrain
completely anonymously. Without a pixeldrain account you can
upload files, download files and create lists of files. And view
your uploaded files on the <a href="/history">history page</a>.
This page only shows files which were uploaded anonymously in
this web browser.
</p>
<p>
By registering an account on pixeldrain you will be able to
access your files from any device with a web browser. Files you
upload and lists you create will be linked to your pixeldrain
account and will show up on your <a href="/user">personal home
page</a>.
</p>
<h3>What cookies does pixeldrain use?</h3>
<p>
When logging in to a pixeldrain account a cookie named
'pd_auth_key' will be installed. This cookie keeps your login
session active. When you delete it you will be logged out of
your account.
</p>
<p>
When you use the style selector on the <a
href="/appearance">Appearance</a> page a cookie called 'style'
will be set. This cookie controls the appearance of the website
for you.
</p>
<p>
When uploading a file pixeldrain will save a list of file links
on your browser's local storage. This data is
<b>only</b> used for viewing your upload history on the <a
href="/history">history page</a>.

<h1>Pixeldrain API documentation</h1>
<div class="page_content"><div class="limit_width">
<p>
Welcome to the pixeldrain API documentation.
<br/>
The methods for uploading and retrieving files don't require an
API key. The methods for creating and retrieving lists also
don't require an API key. All methods which delete or modify a
resource <strong>do</strong> require an API key.
<br/>
API keys can be obtained from the login API.
</p>
<p>
Some JSON responses include fields which end in "_href" (some
people don't know this, but "href" stands for "Hypertext
Reference", the more you know). These point to different places
in the API, which you can retrieve with a GET request. The path
is to be appended to the API URL, so "/file/someid/thumbnail"
becomes "{{apiUrl}}/file/someid/thumbnail".
</p>
<p>
The base URL for the API is "{{apiUrl}}", all paths below are
relative to that URL.
</p>
<h2>Form value order</h2>
<p>
I recommend you put files at the end of every file upload form.
By doing this the pixeldrain server can respond to malformed
requests before the file upload finishes and this may save you a
lot of time and bandwidth when uploading large files. Make sure
your HTTP client has support for premature responses, pixeldrain
uses them a lot. If the server responds before your request is
finished it will always indicate an error and you may abort the
connection.
</p>

<div>
<h3>Description</h3>
<p>
Returns the full file associated with the ID. Supports
byte range requests.
</p>
<p>
When '?download' is added to the URL the server will send an
attachment header instead of inline rendering, which causes the
browser to show a 'Save File' dialog.
</p>
<p>
Warning: If a file is using too much bandwidth it can be rate
limited. The rate limit will be enabled if a file has ten times more
downloads than views. The owner of a file can always download it.
When a file is rate limited the user will need to fill out a captcha
in order to continue downloading the file. The captcha will only
appear on the file viewer page (pixeldrain.com/u/{id}). Rate
limiting has been added to prevent the spread of viruses and to stop
direct linking.
</p>
<p>
Pixeldrain also includes a virus scanner. If a virus has been
detected in a file the user will also have to fill in a captcha to
download it.
