API without a second plan
The Sign API comes with Flaxxa plans that include API access, not a separate subscription.
Dropbox Sign, formerly HelloSign, is a focused e-signature tool tied closely to Dropbox, with a separately priced API. Flaxxa Sign covers the same simple signing, templates, signing order and an audit certificate, and its API comes with Flaxxa plans that include API access.
