Signature API

The signing API built for agents — and the humans they represent.

Every dashboard capability is available over the API with scoped credentials. Agents prepare and route envelopes, and where you authorize it, machine identities sign with the same evidentiary rigor as people — including flows that pair with emerging agent-to-agent commerce models.

Scoped API keys, idempotency, and webhooks suited to autonomous orchestration.

Actor attribution in the audit trail: human, API integration, recipient token, or delegated agent.

One envelope model for traditional sales contracts and programmatic agent commerce.
