=head1 DESCRIPTION

This module allows you to interact with the Sirene API of INSEE (Institut National de la Statistique et des Études Économiques) in France.

It contains a set of functions that can perform searches on INSEE's database to get some information about french companies like their SIREN number, company name, company headquarters address, etc.

The terms "enterprise", "legal unit" and "establishment" used in this documentation are defined at the INSEE website in the following pages:

=head1 CONSTANTS

=head2 DEFAULT_MAX_RESULTS

The API's default number of results for each request. You can override it with the C<< setMaxResults >> method. A too big value may impact response time and general performances.

This constant is set to 20 results.

=head2 DEFAULT_TIMEOUT

This constant specifies how many seconds the client module has to wait for server response before giving up. You can override it with the C<< setTimeout >> method.

This constant is set to 20 seconds.

=head2 HARD_MAX_RESULTS

The maximum number of results that you can get. This value can't be increased (restricted by API). If you try to send a request with a higher value, the C<nombre> parameter will be forced to HARD_MAX_RESULTS value.

This constant is set to 1000 results.

=head2 MAX_SIREN_LENGTH

A SIREN number has a maximum length of 9 digits.

=head2 MAX_SIRET_LENGTH

A SIREN number has a maximum length of 14 digits.

=head2 MIN_LENGTH

In order to avoid useless requests with too short SIREN/SIRET numbers, the module requires at least 3 digits to allow you performing a search.
