Start here

If you are using the FastPix Python SDK for the first time, follow these steps in order:

  1. Check your Python version
  2. Create a Python project
  3. Install the SDK
  4. Verify the installation
  5. Configure authentication
  6. Initialize the FastPix client
  7. Make your first API request
  8. Verify the API response
  9. Understand the media workflow

Do not skip the verification step. If installation or authentication fails, troubleshoot that problem before continuing to the next API operation.

Before you begin

To use the SDK make sure you have:

  • Python 3.9.2 or later.
  • Internet access.
  • A FastPix account.
  • A FastPix Access Token.
  • A FastPix Secret Key.

FastPix uses Basic Authentication:

SDK value FastPix credential
username Access Token
password Secret Key

You can obtain your credentials from the FastPix Dashboard. Follow the steps in the Authentication with Basic Auth guide to obtain your credentials.

1. Check your Python version

python3 --version

Output is similar to:

Python 3.9.2

or a later version.

If your Python version is earlier than 3.9.2, install a supported version before continuing.

2. Create a Python project

a. Create a new directory for your FastPix application:

mkdir fastpix-python-demo
cd fastpix-python-demo

b. Create a virtual environment:

python3 -m venv .venv

c. Activate the virtual environment.

macOS and Linux

source .venv/bin/activate

Windows

.venv\Scripts\activate

d. Verify that the virtual environment is active:

python --version

3. Install the SDK

Using pip

pip install fastpix-python

Using uv

uv add fastpix-python

Using Poetry

poetry add fastpix-python

4. Verify the installation

Before making an API request, verify that Python can import the SDK:

python -c "import fastpix_python; print('FastPix SDK installed successfully')"

Output is similar to:

FastPix SDK installed successfully

If this command fails, do not continue to API calls.

Check:

  • The virtual environment is active.
  • fastpix-python is installed.
  • The Python interpreter belongs to the expected virtual environment.
  • Your Python version is supported.

You can verify the installed package with:

pip show fastpix-python

5. Configure authentication

FastPix uses Basic Authentication.

Set the Access Token and Secret Key as environment variables:

macOS and Linux

export FASTPIX_USERNAME="<YOUR_ACCESS_TOKEN>"
export FASTPIX_PASSWORD="<YOUR_SECRET_KEY>"

Windows PowerShell

$env:FASTPIX_USERNAME="<YOUR_ACCESS_TOKEN>"
$env:FASTPIX_PASSWORD="<YOUR_SECRET_KEY>"

The SDK maps these variables as follows:

FASTPIX_USERNAME → Access Token
FASTPIX_PASSWORD → Secret Key

Verify the credentials are set

Do not print the actual credential values.

Instead, run:

python -c "import os; print('Access Token:', 'set' if os.getenv('FASTPIX_USERNAME') else 'missing'); print('Secret Key:', 'set' if os.getenv('FASTPIX_PASSWORD') else 'missing')"

Output is similar to:

Access Token: set
Secret Key: set

Security

Never:

  • Commit credentials to Git.
  • Put credentials directly into source code.
  • Include credentials in screenshots, logs, or bug reports.
  • Print authentication headers during debugging in production.

Use environment variables or a secure credential-management system.

6. Initialize the FastPix client

a. Create a file named example.py:

import os
from fastpix_python import Fastpix, models

fastpix = Fastpix(
    security=models.Security(
        username=os.getenv("FASTPIX_USERNAME"),
        password=os.getenv("FASTPIX_PASSWORD"),
    ),
)

print("FastPix client initialized")

b. Run:

python example.py

Output is similar to:

FastPix client initialized

What this code does

Fastpix is the top-level SDK client.

models.Security contains the credentials used to authenticate API requests.

The SDK client does not make an API request simply because it is initialized.

An API request occurs when you call an operation such as:

fastpix.input_video.create_media(...)

7. Make your first API request

The easiest way to verify the complete integration is to create media from a publicly accessible video URL.

FastPix provides a sample video URL:

https://static.fastpix.com/fp-sample-video.mp4

a. Replace the contents of example.py with:

import json
import os
from fastpix_python import Fastpix, models

with Fastpix(
    security=models.Security(
        username=os.getenv("FASTPIX_USERNAME"),
        password=os.getenv("FASTPIX_PASSWORD"),
    ),
) as fastpix:
    response = fastpix.input_video.create_media(
        inputs=[
            {
                "type": "video",
                "url": "https://static.fastpix.com/fp-sample-video.mp4",
            },
        ],
        access_policy="public",
        metadata={
            "source": "fastpix-python-demo",
        },
    )

    print(
        json.dumps(
            response.model_dump(
                mode="json",
                by_alias=True,
                exclude_unset=True,
            ),
            indent=2,
        )
    )

b. Save the file and run:

python example.py

8. Verify the API response

A successful request returns a response containing a media ID.

The response has the following general structure:

{
  "success": true,
  "data": {
    "id": "..."
  }
}

The value of:

data.id

is the unique ID assigned to the media.

Save the media ID

You will need the media ID for subsequent media operations.

For example:

MEDIA_ID=<value returned in data.id>

Do not confuse a media_id with a playback_id.

They identify different resources and are used for different operations.

9. Understand the media workflow

Creating media is usually the first operation in an on-demand video workflow.

The basic workflow is:

FastPix media workflow: create media returns a media ID, retrieve the media, check status until ready, create a playback ID, then play the video.

The media ID is the identifier you carry from one operation to the next.

A playback ID is created separately when you need playback access.

More examples: For runnable, end-to-end flows (direct upload, live streaming, playlists, analytics, and more), see the examples/ directory in the repo.

Common tasks

Create media

Goal: Create a FastPix media asset from a video URL.

SDK method:

fastpix.input_video.create_media(...)

Required information:

  • Video URL.
  • Access policy.

Example:

response = fastpix.input_video.create_media(
    inputs=[
        {
            "type": "video",
            "url": "https://static.fastpix.com/fp-sample-video.mp4",
        },
    ],
    access_policy="public",
)

Result:

Save the media ID from:

response.data.id

Next steps

After verifying your integration, you can use the SDK to:

  • Manage media — list, retrieve, update, and delete media.
  • Create playback IDs — generate playback access for your media.
  • Manage live streams — create and manage live streaming sessions.
  • Create playlists — organize media into playlists.
  • Manage signing keys — create and manage keys for secure playback.
  • Analyze video performance — retrieve metrics, views, dimensions, and errors.
  • Use in-video AI — generate subtitles, summaries, chapters, and named entities.
  • Manage media tracks — add, update, and delete audio or subtitle tracks.

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a RetryConfig object to the call:

import os
import json
from fastpix_python import Fastpix, models
from fastpix_python.utils import BackoffStrategy, RetryConfig


with Fastpix(
    security=models.Security(
        username="your-access-token",
        password="your-secret-key",
    ),
) as fastpix:

    res = fastpix.input_video.create_media(
        inputs=[
            {
                "type": "video",
                "url": "https://static.fastpix.com/fp-sample-video.mp4",
            },
        ],
        access_policy="public",
        metadata={
            "key1": "value1",
        },
        retries=RetryConfig(
            "backoff",
            BackoffStrategy(1, 50, 1.1, 100),
            False
        ),
    )

    print(json.dumps(res.model_dump(mode="json", by_alias=True, exclude_unset=True), indent=2))

If you'd like to override the default retry strategy for all operations that support retries, you can use the retry_config optional parameter when initializing the SDK:

import os
import json
from fastpix_python import Fastpix, models
from fastpix_python.utils import BackoffStrategy, RetryConfig


with Fastpix(
    retry_config=RetryConfig(
        "backoff",
        BackoffStrategy(1, 50, 1.1, 100),
        False
    ),
    security=models.Security(
        username="your-access-token",
        password="your-secret-key",
    ),
) as fastpix:

    res = fastpix.input_video.create_media(
        inputs=[
            {
                "type": "video",
                "url": "https://static.fastpix.com/fp-sample-video.mp4",
            },
        ],
        access_policy="public",
        metadata={
            "key1": "value1",
        },
    )

    print(json.dumps(res.model_dump(mode="json", by_alias=True, exclude_unset=True), indent=2))

Error Handling

FastpixError is the base class for all HTTP error responses. It has the following properties:

Property Type Description
err.message str Error message
err.status_code int HTTP response status code eg 404
err.headers httpx.Headers HTTP response headers
err.body str HTTP body. Can be empty string if no body is returned.
err.raw_response httpx.Response Raw HTTP response

Example

import os
import json
from fastpix_python import Fastpix, errors, models


with Fastpix(
    security=models.Security(
        username="your-access-token",
        password="your-secret-key",
    ),
) as fastpix:
    try:
        res = fastpix.input_video.create_media(
            inputs=[
                {
                    "type": "video",
                    "url": "https://static.fastpix.com/fp-sample-video.mp4",
                },
            ],
            access_policy="public",
            metadata={
                "key1": "value1",
            },
        )
        print(json.dumps(res.model_dump(mode="json", by_alias=True, exclude_unset=True), indent=2))
    except errors.FastpixError as e:
        print(e.message)
        print(e.status_code)
        print(e.body)
        print(e.headers)
        print(e.raw_response)

Error Classes

Primary error:

Less common errors (5)

Network errors:

Inherit from FastpixError:

  • ResponseValidationError: Type mismatch between the response data and the expected Pydantic model. Provides access to the Pydantic validation error via the cause attribute.

Server Selection

Override Server URL Per-Client

The default server can be overridden globally by passing a URL to the server_url: str optional parameter when initializing the SDK client instance. For example:

import os
import json
from fastpix_python import Fastpix, models


with Fastpix(
    server_url="https://api.fastpix.com/v1/",
    security=models.Security(
        username="your-access-token",
        password="your-secret-key",
    ),
) as fastpix:

    res = fastpix.input_video.create_media(
        inputs=[
            {
                "type": "video",
                "url": "https://static.fastpix.com/fp-sample-video.mp4",
            },
        ],
        access_policy="public",
        metadata={
            "key1": "value1",
        },
    )

    print(json.dumps(res.model_dump(mode="json", by_alias=True, exclude_unset=True), indent=2))

Custom HTTP Client

The Python SDK makes API calls using the httpx HTTP library. In order to provide a convenient way to configure timeouts, cookies, proxies, custom headers, and other low-level configuration, you can initialize the SDK client with your own HTTP client instance.

Depending on whether you are using the sync or async version of the SDK, you can pass an instance of HttpClient or AsyncHttpClient respectively, which are Protocol's ensuring that the client has the necessary methods to make API calls.

This allows you to wrap the client with your own custom logic, such as adding custom headers, logging, or error handling, or you can just pass an instance of httpx.Client or httpx.AsyncClient directly.

For example, you could specify a header for every request that this SDK makes as follows:

from fastpix_python import Fastpix, models
import httpx

http_client = httpx.Client(headers={"x-custom-header": "someValue"})
s = Fastpix(
    client=http_client,
    security=models.Security(
        username="your-access-token",
        password="your-secret-key",
    ),
)

Or you could wrap the client with your own custom logic:

from fastpix_python import Fastpix, models
from fastpix_python.httpclient import AsyncHttpClient
import httpx
from typing import Union, Optional, Any

class CustomClient(AsyncHttpClient):
    client: AsyncHttpClient

    def __init__(self, client: AsyncHttpClient):
        self.client = client

    async def send(
        self,
        request: httpx.Request,
        *,
        stream: bool = False,
        auth: Union[
            httpx._types.AuthTypes, httpx._client.UseClientDefault, None
        ] = httpx.USE_CLIENT_DEFAULT,
        follow_redirects: Union[
            bool, httpx._client.UseClientDefault
        ] = httpx.USE_CLIENT_DEFAULT,
    ) -> httpx.Response:
        request.headers["Client-Level-Header"] = "added by client"

        return await self.client.send(
            request, stream=stream, auth=auth, follow_redirects=follow_redirects
        )

    def build_request(
        self,
        method: str,
        url: httpx._types.URLTypes,
        *,
        content: Optional[httpx._types.RequestContent] = None,
        data: Optional[httpx._types.RequestData] = None,
        files: Optional[httpx._types.RequestFiles] = None,
        json: Optional[Any] = None,
        params: Optional[httpx._types.QueryParamTypes] = None,
        headers: Optional[httpx._types.HeaderTypes] = None,
        cookies: Optional[httpx._types.CookieTypes] = None,
        timeout: Union[
            httpx._types.TimeoutTypes, httpx._client.UseClientDefault
        ] = httpx.USE_CLIENT_DEFAULT,
        extensions: Optional[httpx._types.RequestExtensions] = None,
    ) -> httpx.Request:
        return self.client.build_request(
            method,
            url,
            content=content,
            data=data,
            files=files,
            json=json,
            params=params,
            headers=headers,
            cookies=cookies,
            timeout=timeout,
            extensions=extensions,
        )

s = Fastpix(
    async_client=CustomClient(httpx.AsyncClient()),
    security=models.Security(
        username="your-access-token",
        password="your-secret-key",
    ),
)

Debugging

You can setup your SDK to emit debug logs for SDK requests and responses.

You can pass your own logger class directly into your SDK.

from fastpix_python import Fastpix, models
import logging

logging.basicConfig(level=logging.DEBUG)
s = Fastpix(
    debug_logger=logging.getLogger("fastpix_python"),
    security=models.Security(
        username="your-access-token",
        password="your-secret-key",
    ),
)

You can also enable a default debug logger by setting an environment variable FASTPIX_DEBUG to true.
