# Backfill Grading

`POST /dialer/parallel-calls/grading/backfill`

## Request

- Base URL: `https://be.graph8.com/api/v1`
- URL: `https://be.graph8.com/api/v1/dialer/parallel-calls/grading/backfill`
- Auth: HTTP bearer

CONTACTS NOBODY - but it SPENDS, and it can spend a lot.

With `dry_run=false` this runs AI grading over EVERY ungraded call with a
transcript in the window - a model invocation each, one call every two
seconds, with no ceiling other than how many calls exist. On a busy
organisation over 365 days that is an unbounded bill from one request.

`dry_run` defaults to TRUE and genuinely short-circuits before any grading
(`parallel_calls.py:4602`), returning the eligible count and a sample.
Call it that way first and read the count.

Tiered `billable`, not `write`: it reaches a paid model per record.

## Query parameters

- `days` integer: How far back to look.
- `dry_run` boolean: `true` counts and samples; `false` GRADES AND SPENDS.

## Headers

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

## Response `200`

Successful Response

- ApiResponseDialerPayload
  - `data` DialerPayload, required: An open envelope for one dialer result. Open because voice owns the shape of a session, a call stub and a queue stat, and it grows them without a contract bump here. A dropped field would otherwise turn an added upstream field into a removed public one.
  - `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.
