=head1 NAME

AI::Image - Generate images using OpenAI's DALL-E

=head1 VERSION

Version 0.1

=head1 SYNOPSIS

    use AI::Image;

    my $ai = AI::Image->new(
        'key'   => 'sk-......',
    );
    
    my $image_url = $ai->image("A photorealistic image of a cat wearing a top hat and monocle.");

    print $image_url;

=head1 DESCRIPTION

This module provides a simple interface to generate images using OpenAI's DALL-E API.

=head1 API KEYS

A free OpenAI API can be obtained from L<https://platform.openai.com/account/api-keys>

=head1 MODELS

Although the API Key is free, each use incurs a cost.  This is dependent on the
model chosen and the size.  The 'dall-e-3' model produces better images but at a
higher cost.  Likewise, bigger images cost more.
The default model C<dall-e-2> with the default size of C<512x512> produces resonable
results at a low cost and is a good place to start using this module.

See also L<https://platform.openai.com/docs/models/overview>

=head1 METHODS

=head2 new

  my $ai = AI::Image->new(%params);

Creates a new AI::Image object.

=head3 Parameters

=over 4

=item key

C<required> Your OpenAI API key.

=item api

The API to use (currently only 'OpenAI' is supported).

=item model

The language model to use (default: 'dall-e-2').

See L<https://platform.openai.com/docs/models/overview>

=item size

The size for the generated image (default: '512x512').

=item debug

Used for testing.  If set to any true value, the image method
will return details of the error encountered instead of C<undef>

=back

=head2 image

  my $url = $ai->image($prompt);

Generates an image based on the provided prompt and returns the URL of the generated image.  The URL is valid for 1 hour.

=head3 Parameters

=over 4

=item prompt

The textual description of the desired image.

=back

=head2 success

  my $success = $ai->success();
