A Python interface to the Akismet spam-filtering service.

Two API clients are available from this library:

• akismet.SyncClient is an Akismet API client which performs synchronous (blocking) HTTP requests to the Akismet web service.
• akismet.AsyncClient is an Akismet API client which performs asynchronous (async/await/non-blocking) HTTP requests to the Akismet web service.

Aside from one being sync and the other async, the two clients expose identical APIs, and implement all methods of the Akismet web API.

To use this library, you will need to obtain an Akismet API key and register a site for use with the Akismet web service; you can do this at <https://akismet.com>. Once you have a key and corresponding registered site URL to use with it, place them in the environment variables PYTHON_AKISMET_API_KEY and PYTHON_AKISMET_BLOG_URL, and they will be automatically detected and used.

You can then construct a client instance and call its methods. It's recommended that you always use a client construction method which will automatically validate your API key with the Akismet web service. You can do this by creating your client as a context manager, in which case the key is automatically validated on entering the with block:

import akismet

with akismet.SyncClient() as akismet_client:
    if akismet_client.comment_check(
        user_ip=submitter_ip,
        comment_content=submitted_content,
        comment_type="forum-post",
        comment_author=submitter_name
    ):
        # This piece of content was classified as spam; handle it appropriately.

Or using the asynchronous client:

import akismet

async with akismet.AsyncClient() as akismet_client:
    if await akismet_client.comment_check(
        user_ip=submitter_ip,
        comment_content=submitted_content,
        comment_type="forum-post",
        comment_author=submitter_name
    ):
        # This piece of content was classified as spam; handle it appropriately.

Or you can use the validated_client() constructor method, which will validate your key when constructing the client instance:

import akismet

akismet_client = akismet.SyncClient.validated_client()

if akismet_client.comment_check(
    user_ip=submitter_ip,
    comment_content=submitted_content,
    comment_type="forum-post",
    comment_author=submitter_name
):
    # This piece of content was classified as spam; handle it appropriately.

Or using the asynchronous client:

import akismet

akismet_client = await akismet.AsyncClient.validated_client()

if await akismet_client.comment_check(
    user_ip=submitter_ip,
    comment_content=submitted_content,
    comment_type="forum-post",
    comment_author=submitter_name
):
    # This piece of content was classified as spam; handle it appropriately.
