# Automate LLC Formation and Compliance Filings via API

> State formation filings, annual reports, registered agent correspondence, and compliance notices — mailed to state offices with certified delivery proof. An AI agent can manage all 50 states from one workflow.

## What gets mailed

- Articles of organization / incorporation
- Annual reports and biennial reports
- Amendments (name changes, address changes, member changes)
- Registered agent change notices
- Certificates of good standing requests
- Dissolution and withdrawal filings
- Cover letters with filing fee checks

## Why certified mail for state filings

- Proves the filing was submitted by the deadline
- If a state office loses the filing, USPS proof of mailing protects good standing
- Some states require certified mail for certain amendments and dissolutions

## The agent workflow

1. Agent monitors annual report deadlines across all 50 states
2. System generates the correct form with entity data pre-filled
3. POST the filing PDF to mailbox.bot with Secretary of State as recipient
4. Certified mail tracking confirms delivery
5. If state doesn't acknowledge within expected timeframe, agent flags for follow-up
