Why developers look beyond OneSpan Sign
OneSpan Sign (formerly eSignLive) is built for banks and large enterprises. If that's not you, these are the trade-offs:
Built for regulated enterprises
OneSpan Sign targets banks, insurers and government, with compliance features to match. A startup sending contracts from code may not need them.
Enterprise pricing through sales
Third-party listings show per-user plans from about $20 per user per month; enterprise and volume pricing is quoted by sales.
More than typical contracts need
Bank-grade security features matter in regulated industries. For typical SaaS agreements, they can be capability you pay for but don't use.
Why APISign can be the better fit
We built APISign for developers who need simple, affordable e-signatures without the enterprise overhead.
REST, MCP and CLI
A REST API with an x-api-key header, a remote MCP server with 12 tools for AI agents, and the apisign-io CLI.
Transparent pricing
$0.25 per send, and a resend counts as a send. Test sends are free. No subscription, no seats.
Markdown templates
Define contracts in Markdown with {{variables}}, or import a .docx. No proprietary document builder to learn.
