How It Works

Four steps from API call to active legal entity. Only one requires human time.

01
POST /v1/entity-orders

Agent Creates Order

Agent submits jurisdiction, entity type, member details, and authority scope in a single API call. Formation ID returned immediately.

02
Name Check + Payment

Name & Payment

Agent runs name availability against the state entity database. On confirmation, formation fee is charged to the payment method on file.

03
Human Kernel

5-Minute Human Session

Agent creates a secure kernel session via API and relays the URL to the human owner. They complete SSN, KYC, and operating agreement signature. Webhook fires on completion.

04
Formation Complete

Entity Active

Documents generated, state filing submitted, EIN applied for automatically. Formation webhooks pushed at each stage: filed, active, EIN assigned.

Pricing

Flat fees. No hourly billing. State filing fees and registered agent included.

Agent Discovery

Built for Agents

The API is designed to be discovered and consumed by autonomous agents — not just developers reading documentation.

llms.txt

Structured discovery file for LLM-native agents. Lists endpoints, entity types, pricing, and formation flow.

OpenAPI 3.1

Full OpenAPI spec for REST clients. Describes every endpoint, schema, and webhook payload.

MCP Server

Claude and compatible agents can use native MCP tools. No REST client required for supported agent frameworks.

ai-plugin.json

ChatGPT Plugin manifest for GPT-based agents. Auto-discoverable at the well-known path.

Create an Entity Order

A single POST request starts formation. The agent receives a formation ID and webhook updates at every stage.
