`GET /sequencer/channels/capacity-estimate`

## Request

- Base URL: `https://be.graph8.com/api/v1`
- URL: `https://be.graph8.com/api/v1/sequencer/channels/capacity-estimate`
- Auth: HTTP bearer

How many mailboxes and domains a target volume needs, and what it costs.

Read-only: it computes an estimate and buys nothing.

## Query parameters

- `contacts_per_month` integer, required: Target contacts to reach per month.
- `warmed` boolean: False = cold start (25/day); True = warmed (100/day).
- `domain_tld` string: TLD for the per-domain USD cost estimate.

## Headers

- `Authorization` string, nullable
- `X-Target-Org-Id` string, nullable

## Response `200`

Successful Response

- ApiResponseAny
  - `data` unknown, required
  - `pagination` PaginationMeta
    - `page` integer, required: Current page number (1-indexed)
    - `limit` integer, required: Items per page
    - `total` integer, required: Total number of items
    - `has_next` boolean, required: Whether there are more pages
    - `next_cursor` string, nullable: Opaque cursor for the next page; null when there are no more items. Pass it back as the `cursor` query param to fetch the following page without computing page numbers.
    - `total_available` integer, nullable: Search endpoints only: how many records really match, when known. Can be larger than `total`, which is capped at the 10,000 results that can be paged. For company search this is a distinct-company estimate. Null when unknown; absent outside search.
    - `total_is_lower_bound` boolean, nullable: Search endpoints only: true when more records match than `total` shows (the result set is larger than the 10,000 results that can be paged). Absent outside search.
    - `notes` string[], nullable: Search endpoints only: plain-language notes about the result, e.g. that more records match than can be paged, or that a reversed `between` range was put in order.
