Install packagist.org/packages/ramlev/kireifilter

$ composer require ramlev/kireifilter

Client setup

use Ramlev\Kireifilter\KireifilterClient;

$client = new KireifilterClient('kf_live_...');

// One argument: your API token.
// Guzzle is bundled — no extra wiring.

Check + handle result

$result = $client->check(
    type:     'comment',
    content:  $input->getContent(),
    metadata: ['ip' => $request->getClientIp()],
);

if ($result->isSpam) {
    // block, flag, or queue for review
}

// $result->score     float 0.0–1.0
// $result->reasons   string[]
// $result->id        int  (server-side ID)

Detection pipeline

Independent layers run in sequence. Scores accumulate; high-confidence matches short-circuit the chain.

#	Layer	What it checks
1	Custom rules Pro+	Your own allow and deny lists applied before anything else
2	IP & sender reputation	Real-time blocklists, prior submission history, and repeat offenders
3	Content analysis	Links, patterns, obfuscation attempts, and text quality signals
4	Email intelligence	Address validity, spoofing, authentication, and throwaway detection

Get started in three steps

1

Create an account

Free plan included — no credit card required.
2

Generate an API token

From the dashboard settings. You can create and revoke tokens at any time.
3

Run composer require ramlev/kireifilter

Call $client->check() before persisting data. Act on $result->isSpam — reject, queue for review, or pass through. Raw HTTP also works.
