Frequently asked questions¶

The following notes answer common questions, and may be useful to you when using akismet.

What versions of Python are supported?¶

The 25.10.0 release of akismet supports the following versions of Python:

Python 3.10
Python 3.11
Python 3.12
Python 3.13
Python 3.14

Older versions of Python are not supported and will cause errors.

Do I have to send all the optional arguments?¶

The Akismet web service supports a large number of optional arguments to provide additional information for classification and training. You can submit as many of them as you wish with the comment_check, submit_ham, and submit_spam operations. The Akismet documentation recommends sending as much information as possible, though only the user_ip argument to those methods is actually required.

Is this only for blog comments?¶

The Akismet web service can handle many types of user-submitted content, including comments, contact-form submissions, user signups and more. See Akismet’s documentation of the comment check operation for details.

Why doesn’t the default constructor validate the config?¶

Both of the Akismet API clients provide an alternate constructor – akismet.SyncClient.validated_client() and akismet.AsyncClient.validated_client() – and you’re encouraged to use these nearly any time you want an instance of an Akismet API client (the exception is using a client as a context manager – see below), because the validated_client() constructor will validate your Akismet configuration (via the verify-key API operation) automatically. If you don’t do this, you’ll need to call verify_key() manually (and ideally only once for each client instance).

The technical reason for this is that the validated_client() constructor allows both the sync and async clients to provide the same interface. SyncClient could perform the validation in its __init__() method, but AsyncClient cannot, because its verify_key() method is asynchronous; calling it in __init__() would require making the __init__() method asynchronous too, and an async __init__() is not currently supported by Python.

This limitation does not apply to classmethods used as alternate constructors, so to perform automatic validation of your Akismet configuration, AsyncClient defines the alternate constructor validated_client(). And to ensure both client classes have the same interface, SyncClient also provides a validated_client() constructor.

Using either client class as a context manager does not have this technical limitation (the entry method of an async context manager is async, so the verify-key operation can be called there), so using one of the Akismet client classes as a context manager does not require using the alternate constructor.

How do I check my key?¶

The simplest way is to either:

Use akismet.SyncClient.validated_client() / akismet.AsyncClient.validated_client(), or
Create a client as a context manager (e.g., with akismet.SyncClient() as akismet_client or async with akismet.AsyncClient() as akismet_client)

Either of these approaches automatically verifies the key and URL for you, and will raise APIKeyError if the key is invalid.

If you’re not able to do this, you can also manually instantiate a client and then call its verify_key() method, passing the key and URL you want to check as the arguments. For example:

Sync

import akismet

client = akismet.SyncClient()
if not client.verify_key(key_to_test, url_to_test):
    # The key/URL were invalid.

Async

import akismet

client = akismet.AyncClient()
if not await client.verify_key(key_to_test, url_to_test):
    # The key/URL were invalid.

How can I test that it’s working?¶

akismet provides test-client implementations you can use in your own application’s tests; it also provides its own thorough test suite you can run to verify its behavior, and you can perform some live end-to-end testing through the standard Akismet API clients. See the testing guide for details.

What user-agent string is sent by `akismet`?¶

The Akismet web service documentation recommends sending a string identifying the application or platform with version, and Akismet plugin/implementation name with version. In accordance with this, akismet sends an HTTP User-Agent based on the versions of Python and akismet in use. For example, akismet 24.4.0 on Python 3.10.4 will send akismet.py/24.4.0 | Python 3.10.4.

Does `akismet` support the “pro-tip” header?¶

For content determined to be “blatant” spam (and thus which does not need to be placed into a queue for review by a human), the Akismet web service will add the header X-akismet-pro-tip: discard to its comment-check response.

The comment-check operations of both the sync and async clients provide a mechanism to read this, expressed through the CheckResponse enum.
