Describe the agreement in plain language and get a contract back, from scratch or from your own template, with recipients and placeholder data filled in. One request, ready for signing.
Contracts in free format
Ask for a contract using your own context and best practices. Optionally name the recipients and their email addresses.
From your templates
Generate a contract from a template by name, and fill in its placeholders with the data you pass in the same message.
Explore your library
Ask for the list of your templates or the placeholders of a template, without building separate API calls.
Preview and contract key
When a contract is created, you get its contract key for the rest of the API and a preview link to check the result.
