# Get Capacity Plan

`GET /deliverability/capacity-plan`

## Request

- Base URL: `https://be.graph8.com/api/v1`
- URL: `https://be.graph8.com/api/v1/deliverability/capacity-plan`
- Auth: HTTP bearer

How much sending capacity a target volume needs, and what the shortfall costs.

RECOMMENDATION ONLY. It buys nothing and holds nothing - the credit figure
it returns is an estimate of what closing the gap WOULD cost. The buying
is `POST /mailboxes/schedule-buy/plans`, which is a separate, deliberate
act.

## Query parameters

- `contacts_per_month` integer, required: Volume you intend to send per month.
- `delivery_days` integer: Days you want to spread that volume over.
- `warmed` boolean: Assume new mailboxes must warm up before they count as capacity.
- `domain_tld` string: Extension to price against.
- `exclude_committed` boolean: Treat the target as ADDITIONAL volume: mailboxes already in live sequences are not capacity.

## Headers

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

## Response `200`

Successful Response

- ApiResponseMailboxDomainPayload
  - `data` MailboxDomainPayload, required: An open envelope for one provider/deliverability result. Open on purpose. These payloads are provider state and advisory reads whose contents grow with the product, and a dropped field reads as "nothing to report" rather than "we did not tell you". Every value passes through ``scrub_vendor_names`` on the way in.
  - `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.
