Kita Transcripts API

openapi: 3.2.0
info:
  title: Kita AI Underwriter Transcripts API
  version: v1
  summary: Create loan applications, upload borrower documents, and retrieve a deterministic credit picture and cited credit memo.
  description: 'The Kita AI Underwriter API turns borrower documents into a decision-ready credit file.

    Create an application, push documents, and poll for extraction, the deterministic credit

    picture (spread, adjustments, policy decision), and a cited credit memo.


    Authentication uses an organization API key prefixed `kita_uw_`, sent as either

    `Authorization: ApiKey <key>` or `Authorization: Bearer <key>`. Two scopes are enforced

    per endpoint: `read` for GET endpoints and `write` for mutations.


    Errors return `{ "message": "..." }` with a standard HTTP status. `POST /intake` is

    idempotent on `external_ref`.
