Price: Free tier
Free trial: Yes
API authentication: API requests use HTTP Basic Auth with the Secret Token as the username and no password; browser requests are blocked by CORS to protect the token.

Compliance: The maker lists ESIGN and UETA, eIDAS at the Simple Electronic Signature level, GDPR, HIPAA support, and other regional e-signature frameworks.
Contract format: Contracts use responsive structured text rather than PDFs, and PDF or Word files can be converted into templates before sending.
Data residency: The maker lists data center choices in the United States, Canada, Australia, Germany, and the United Kingdom.
Embedded signing: The API documentation provides iframe instructions for embedding a signer page in another site or product.
Founded: 2015
