Registered Agent API

Stable now supports full Company and Registered Agent management through our REST API. Create a company, assign it to a jurisdiction, and provision a registered agent location, all in a few API calls (docs here).

A Registered Agent location is the address at which Stable, acting as a registered agent, accepts service of process and official state mail on behalf of one of your companies in a single US jurisdiction. Registered Agents are typically required in every state or territory where your legal entity is operating.

What's new:

  • Company endpoints: create, list, get, update, and deactivate (/v1/companies)
  • Registered Agent (RA) location endpoints: create and deactivate
  • GET /v1/locations returns RA locations alongside CMRA locations
  • Input validation for EIN format, jurisdiction requirements, and WY-specific fields
  • Pending status with polling support for async RA provisioning

Redesigned Companies Page

We redesigned the companies page and introduced a few small improvements

  • EIN and State entity ID storage
  • Bulk dismiss Registered Agent creation tasks
  • New tab view for jurisdiction and entity information sections
