Redeyed Sentinel for Laravel

Add Redeyed Sentinel — a self-hosted CAPTCHA + IP-reputation service — to any Laravel app in a couple of minutes.

Sentinel is free to install and completely inert until you set your keys. Before keys are configured the package fails open (verification passes and a warning is logged) so your forms never break. Once your keys are in place, every protected form is verified server-side.

Requirements

• PHP >= 8.1
• Laravel 10 or 11

Installation

composer require redeyed/sentinel-laravel

The service provider is auto-discovered — there is nothing to register manually.

Optionally publish the config:

php artisan vendor:publish --tag=sentinel-config

Configuration

Grab your keys from the Redeyed Lab panel:

• Site key (public): Developer → Sentinel Sites
• API key (secret): Developer → API Keys

Add them to your .env:

SENTINEL_SITE_KEY=your-public-site-key
SENTINEL_API_KEY=your-secret-api-key

# Optional — only change if you self-host Sentinel elsewhere
# SENTINEL_BASE_URL=https://redeyed.com

The SENTINEL_API_KEY is secret and stays server-side — it is only ever sent as the X-Api-Key header during verification and is never exposed to the browser.

Usage

1. Render the widget in your form

Drop the component anywhere inside your <form>:

<form method="POST" action="/register">
    @csrf

    {{-- ...your fields... --}}

    <x-sentinel-captcha />

    <button type="submit">Submit</button>
</form>

Prefer a directive? @sentinel does exactly the same thing:

<form method="POST" action="/register">
    @csrf
    @sentinel
    <button type="submit">Submit</button>
</form>

The widget loads the Sentinel script once per page and injects a hidden input named sentinel-token into your form.

2. Verify on the server

Add the rule to your validation. Either use the rule class:

use Redeyed\LaravelSentinel\Rules\Sentinel;

$request->validate([
    // ...your other rules...
    'sentinel-token' => ['required', new Sentinel],
]);

…or the string alias:

$request->validate([
    'sentinel-token' => ['required', 'sentinel'],
]);

If verification fails the user sees:

Human verification failed — please try again.

How verification works

On submit, the package POSTs to {BASE_URL}/api/v1/verify with the X-Api-Key header and a JSON body of {"site_key": "...", "token": "..."}. The submission passes only when the response reports success === true (both the { "data": { "success": true }, "meta": {} } envelope and a flat { "success": true } shape are supported).

If keys are not configured, verification fails open and logs a warning so forms keep working until you finish setup.
