<Note>This feature is currently in open beta.</Note>

### Concept

We provide our users with the ability to simplify the API request structure, sending unified requests
to Sendforsign's infrastructure and receiving unified responses.

Supported use cases:

* `Create a contract in free format`: Ask the system to generate a contract using your context and best practices. Optionally, specify the recipients' names and email addresses.
* `Create a contract from a template`: Ask the system to generate a contract using a template. Specify the name of the template.
* `Create and fill in a contract from a template`: Provide the template name, the recipients' names and email addresses, and the data to populate the placeholders.
* `See the list of templates`: Retrieve a list of templates created in your account.
* `See the list of template placeholders`: Retrieve a list of placeholders of a template. Specify the name of the template.
