# Size an autopilot budget plan

`POST /autopilot/plan`

## Request

- Base URL: `https://api.emailchaser.com/r`

Turns a monthly budget into a concrete outbound setup: domains, mailboxes, sending volume, prospects and costs. expectedMeetingsPerMonth is a planning ESTIMATE on pessimistic funnel assumptions, not a promise. Changes nothing, but needs a read and write API key.

  - `budgetUsd` number: BudgetUsd is the total monthly budget in dollars, inclusive of the platform subscription. Required, must be greater than zero.
  - `maxMailboxes` integer: MaxMailboxes caps infrastructure regardless of budget. 0 means no cap.
