# Add Agency Statement Line Item

`POST /marketplace/agencies/{slug}/service-statements/{statement_id}/line-items`

## Request

- Base URL: `https://be.graph8.com/api/v1`
- URL: `https://be.graph8.com/api/v1/marketplace/agencies/{slug}/service-statements/{statement_id}/line-items`
- Auth: HTTP bearer

Add commission / bonus / expense / discount. RECOMPUTES THE TOTAL.

This is the money the REP may never put on a client's bill - it belongs to
the agency, which is the party with a commercial stake in the amount.
`retainer` and `meeting` are system-generated from the engagement's rate and
cannot be added by hand, by anyone.

## Path parameters

- `slug` string, required: Agency slug, e.g. `netrion-labs`. You must operate it.
- `statement_id` string, required: Service statement id (UUID).

## Headers

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

## Request body

- LineItemCreateRequest: One money line on a statement. `extra="forbid"` mirrors the app model: a typo'd field is a 422 naming it rather than a silently dropped charge.
  - `kind` 'commission' | 'bonus' | 'expense' | 'discount', required: Only `discount` may carry a negative unit amount.
  - `label` string, required
  - `quantity` union
    - number
    - string
  - `unit_amount_usd` union, required: Signed. Negative is refused unless `kind` is `discount`.
    - number
    - string
  - `source_ref` string, nullable

## Response `201`

Successful Response

- ApiResponseMarketplacePayload
  - `data` MarketplacePayload, required: One record, or one action result.
  - `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.
