+
+        !!! note "api client context manager"
+            It is necessary to use a `with` context manager for the API
+
+        Examples
+        --------
+        ### Create API client with host and token
+        >>> import cript
+        >>> with cript.API(
+        ...     host="https://api.criptapp.org/",
+        ...     api_token=os.getenv("CRIPT_TOKEN"),

+        ...    pass
+
+
+        ---
+
+        ### Creating API Client
+        !!! Warning "Token Security"
+            It is **highly** recommended that you store your API tokens in a safe location and read it into your code
+            Hard-coding API tokens directly into the code can pose security risks,
+            as the token might be exposed if the code is shared or stored in a version control system.
+            Anyone that has access to your tokens can impersonate you on the CRIPT platform
+
+        ### Create API Client with Environment Variables
+
+        Another great way to keep sensitive information secure is by using
+        [environment variables](https://www.freecodecamp.org/news/python-env-vars-how-to-get-an-environment-variable-in-python/).
+        Sensitive information can be securely stored in environment variables and loaded into the code using
+        [os.getenv()](https://docs.python.org/3/library/os.html#os.getenv).
+
+        Examples
+        --------
+        >>> import cript
+        >>> import os
+        >>> # securely load sensitive data into the script
+        >>> cript_host = os.getenv("cript_host")
+        >>> cript_api_token = os.getenv("cript_api_token")
+        >>> cript_storage_token = os.getenv("cript_storage_token")
+        >>> with cript.API(
+        ...     host=cript_host, api_token=cript_api_token, storage_token=cript_storage_token
+        ... ) as api:
+        ...     pass
+
+        ### Create API Client with None
+        Alternatively you can configure your system to have an environment variable of
+        `CRIPT_TOKEN` for the API token and `CRIPT_STORAGE_TOKEN` for the storage token, then
+        initialize `cript.API` `api_token` and `storage_token` with `None`.
+
+        The CRIPT Python SDK will try to read the API Token and Storage token from your system's environment variables.
+
+        ```python
+        with cript.API(host=cript_host, api_token=None, storage_token=None) as api:
+            # write your script
+            pass
+        ```
+
+        ### Create API client with config.json
+        `config.json`
+        ```json
+        {
+            "host": "https://api.criptapp.org/",
+            "api_token": "I am API token",
+            "storage_token": "I am storage token"
+        }
+        ```
+
+        Examples
+        --------
+        `my_script.py`
+        >>> from pathlib import Path
+        >>> import cript
+        >>> # create a file path object of where the config file is
+        >>> config_file_path = Path(__file__) / Path('./config.json')
+        >>> with cript.API(config_file_path=config_file_path) as api:   # doctest: +SKIP
+        ...     # node creation, api.save(), etc.
+        ...     pass
+
+        Parameters
+        ----------
+        host : str, None
+            CRIPT host for the Python SDK to connect to such as https://api.criptapp.org/`
+            This host address is the same address used to login to cript website.
+            If `None` is specified, the host is inferred from the environment variable `CRIPT_HOST`.
+        api_token : str, None
+            CRIPT API Token used to connect to CRIPT and upload all data with the exception to file upload that needs
+            a different token.
+            You can find your personal token on the cript website at User > Security Settings.
+            The user icon is in the top right.
+            If `None` is specified, the token is inferred from the environment variable `CRIPT_TOKEN`.
+        storage_token: str
+            This token is used to upload local files to CRIPT cloud storage when needed
+        config_file_path: str
+            the file path to the config.json file where the token and host can be found
+
+
+        Notes
+        -----
+        * if `host=None` and `token=None`
+            then the Python SDK will grab the host from the users environment variable of `"CRIPT_HOST"`

When verbose is set to False, the class will only provide essential logging information, +making the terminal output less cluttered and more user-friendly.

+ + + +

Examples:

+ 
>>> import cript

+...     api_token=os.getenv("CRIPT_TOKEN"),
+...     storage_token=os.getenv("CRIPT_STORAGE_TOKEN")
+... ) as api:
+...     # turn off the terminal logs
+...     api.verbose = False
+
+ + + +

Returns:

+ + + + + + + + + + + + + +
TypeDescription

+ + + + +
+ + + + +

+ __init__(host=None, api_token=None, storage_token=None, config_file_path='') + +

+ + +
+ +

Initialize CRIPT API client with host and token. +Additionally, you can use a config.json file and specify the file path.

+
+

api client context manager

+

It is necessary to use a with context manager for the API

+
+ + + +

Examples:

+
Create API client with host and token
+ 
>>> import cript
+>>> with cript.API(
+...     host="https://api.criptapp.org/",
+...     api_token=os.getenv("CRIPT_TOKEN"),
+...     storage_token=os.getenv("CRIPT_STORAGE_TOKEN")
+... ) as api:
+...    # node creation, api.save(), etc.
+...    pass
+
+
+
Creating API Client
+
+

Token Security

+

It is highly recommended that you store your API tokens in a safe location and read it into your code +Hard-coding API tokens directly into the code can pose security risks, +as the token might be exposed if the code is shared or stored in a version control system. +Anyone that has access to your tokens can impersonate you on the CRIPT platform

+
+
Create API Client with Environment Variables
+

Another great way to keep sensitive information secure is by using +environment variables. +Sensitive information can be securely stored in environment variables and loaded into the code using +os.getenv().

+ + + +

Examples:

+ 
>>> import cript
+>>> import os
+>>> # securely load sensitive data into the script
+>>> cript_host = os.getenv("cript_host")
+>>> cript_api_token = os.getenv("cript_api_token")
+>>> cript_storage_token = os.getenv("cript_storage_token")
+>>> with cript.API(
+...     host=cript_host, api_token=cript_api_token, storage_token=cript_storage_token
+... ) as api:
+...     pass
+
+
Create API Client with None
+

Alternatively you can configure your system to have an environment variable of +CRIPT_TOKEN for the API token and CRIPT_STORAGE_TOKEN for the storage token, then +initialize cript.API api_token and storage_token with None.

+

The CRIPT Python SDK will try to read the API Token and Storage token from your system's environment variables.

+
with cript.API(host=cript_host, api_token=None, storage_token=None) as api:
+    # write your script
+    pass
+
+
Create API client with config.json
+

config.json +

{
+    "host": "https://api.criptapp.org/",
+    "api_token": "I am API token",
+    "storage_token": "I am storage token"
+}
+

+ + + +

Examples:

+

my_script.py

+ 
>>> from pathlib import Path
+>>> import cript
+>>> # create a file path object of where the config file is
+>>> config_file_path = Path(__file__) / Path('./config.json')
+>>> with cript.API(config_file_path=config_file_path) as api:
+...     # node creation, api.save(), etc.
+...     pass
+
+ + + +

Parameters:

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
NameTypeDescriptionDefault
host + (str, None) + +
+

CRIPT host for the Python SDK to connect to such as https://api.criptapp.org/This host address is the same address used to login to cript website. +IfNoneis specified, the host is inferred from the environment variableCRIPT_HOST`.

+
+ 		+ None +
api_token + (str, None) + +
+

CRIPT API Token used to connect to CRIPT and upload all data with the exception to file upload that needs +a different token. +You can find your personal token on the cript website at User > Security Settings. +The user icon is in the top right. +If None is specified, the token is inferred from the environment variable CRIPT_TOKEN.

+
+ 		+ None +
storage_token + Union[str, None] + +
+

This token is used to upload local files to CRIPT cloud storage when needed

+
+ 		+ None +
config_file_path + Union[str, Path] + +
+

the file path to the config.json file where the token and host can be found

+
+ 		+ '' +
+
Notes
+
    +
  • if host=None and token=None + then the Python SDK will grab the host from the users environment variable of "CRIPT_HOST" + and "CRIPT_TOKEN"
    • +
+ + + +

Warns:

+ + + + + + + + + + + + + +
TypeDescription
+ UserWarning + +
+

If host is using "http" it gives the user a warning that HTTP is insecure and the user should use HTTPS

+
+

TypeDescription
+ CRIPTConnectionError + +
+

If it cannot connect to CRIPT with the provided host and token a CRIPTConnectionError is thrown.

+
+

+
+
+How to get node_type in snake case +

You can get the node type in snake case of a node via: + 

 import cript
+ print(cript.ComputationProcess.node_type_snake_case)
+computation_process
+

+

You can also call api.delete_node_by_uuid() with + 

api.delete(
+    node_type=cript.ComputationProcess.node_type_snake_case,
+    node_uuid="2fd3d500-304d-4a06-8628-a79b59344b2f",
+)
+

+
+
Notes
+

After the node has been successfully deleted, a log is written to the terminal if cript.API.verbose = True

+
INFO: Deleted 'Material' with UUID of '80bfc642-157e-4692-a547-97c470725397' from CRIPT API.
+
+
Warnings
+

After successfully deleting a node from the API, keep in mind that your local Project node in your script +may still contain outdated data as it has not been synced with the API.

+

To ensure you have the latest data, follow these steps:

+
    +
  1. Fetch the newest Project node from the API using the +cript.API.search() provided by the SDK.
    2. +
  2. Deserialize the retrieved data into a new Project node using the +load_nodes_from_json utility function.
    3. +
  3. Replace your old Project node with the new one in your script for accurate and up-to-date information.
    4. +
+ + + +

Parameters:

+ + + + + + + + + + + + + + + + + + + + + + + +
NameTypeDescriptionDefault
node_type + str + +
+

the type of node that you want to delete in snake case

+
+ 		+ required +
node_uuid + str + +
+

the UUID of the primary node, supporting node, or sub-object +that you want to delete from the API

+
+ 		+ required +
+ + + +

Raises:

+ + + + + + + + + + + + + +
TypeDescription
+ APIError + +
+

If the API responds with anything other than HTTP status 200, then the CRIPT Python SDK raises APIError +APIError is raised in case the API cannot delete the specified node. +Such cases can happen if you do not have permission to delete the node +or if the node is actively being used elsewhere in CRIPT platform and the API cannot delete it.

+
+
+ + + +

Returns:

+ download_file(file_source, destination_path='.') + +

+ + +
+ +

Download a file from CRIPT Cloud Storage (AWS S3) and save it to the specified path.

+
+Cloud Storage vs Web URL File Download +

If the object_name does not starts with http then the program assumes the file is in AWS S3 storage, +and attempts to retrieve it via +boto3 client.

+

If the object_name starts with http then the program knows that +it is a file stored on the web. The program makes a simple +GET request to get the file, +then writes the contents of it to the specified destination.

+
+

Note: The current version of the program is designed to download files from the web in a straightforward +manner. However, please be aware that the program may encounter limitations when dealing with URLs that +require JavaScript or a session to be enabled. In such cases, the download method may fail.

+

We acknowledge these limitations and plan to enhance the method in future versions to ensure compatibility +with a wider range of web file URLs. Our goal is to develop a robust solution capable of handling any and +all web file URLs.

+
+
+ + + +

Parameters:

+ + + + + + + + + + + + + + + + + + + + + + + +
NameTypeDescriptionDefault
file_source + str + +
+

object_name: file downloaded via object_name from cloud storage and saved to local storage +object_name e.g. "Data/{file_name}"

+
+

URL file source: If the file source starts with http then it is downloaded via GET request and +saved to local storage +URL file source e.g. https://criptscripts.org/cript_graph_json/JSON/cao_protein.json

+
+ 		+ required +
destination_path + str + +
+

please provide a path with file name of where you would like the file to be saved +on local storage.

+
+

If no path is specified, then by default it will download the file +to the current working directory.

+

The destination path must include a file name and file extension + e.g.: ~/Desktop/my_example_file_name.extension

+
+
+ 		+ '.' +
+ + + +

Examples:

+ 
>>> from pathlib import Path
+>>> import cript
+>>> with cript.API(
+...     host="https://api.criptapp.org/",
+...     api_token=os.getenv("CRIPT_TOKEN"),
+...     storage_token=os.getenv("CRIPT_STORAGE_TOKEN")
+... ) as api:
+...     desktop_path = (Path(__file__).parent / "cript_downloads" / "my_downloaded_file.txt").resolve()
+...     my_file = cript.File(
+...         name="my file node name",
+...         source="https://criptapp.org",
+...         type="calibration",
+...         extension=".csv",
+...     )
+...     api.download_file(file_source=my_file.source, destination_path=str(desktop_path))
+
+ + + +

Raises:

TypeDescription
+ FileNotFoundError + +
+

In case the file could not be found because the file does not exist or the path given is incorrect

+

Paginator

+ +
+ + + + +
+ + + +
+ + + + + + + + +
+ + + + +

+ Paginator + + +

+ + +
+ + +

Paginator is used to flip through different pages of data that the API returns when searching.

+
+

Instead of the user manipulating the URL and parameters, this object handles all of that for them.

+
+

When conducting any kind of search the API returns pages of data and each page contains 10 results. +This is equivalent to conducting a Google search when Google returns a limited number of links on the first page +and all other results are on the next pages.

+

Using the Paginator object, the user can simply and easily flip through the pages of data the API provides.

+
+

Do not create paginator objects

+

Please note that you are not required or advised to create a paginator object, and instead the +Python SDK API object will create a paginator for you, return it, and let you simply use it

+
+ + + +

Attributes:

+ + + + + + + + + + + + + + + +

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param {Observer|Function} observerOrNext (optional) Either an observer with methods to be called,\n * or the first of three possible handlers, which is the handler for each value emitted from the subscribed\n * Observable.\n * @param {Function} error (optional) A handler for a terminal event resulting from an error.
