# Start a knowledge job

`POST https://ai.inovacc.dev/v1/knowledge/jobs`

Start building a knowledge base from a completed upload of a recording.

## Body params

- `upload_id` (string), required: The id of a completed upload of the recording (its `X-Operation-Id` at `POST /v1/uploads`).
- `max_price_usd` (string), required: The most the job may cost, a decimal greater than zero such as `"5.00"`. Over your organization's cap it is refused before any paid work.
- `spoken_language` (string): The language the recording is in, such as `en` or `pt-BR`: a hint for transcription.
- `output_language` (string): The language the knowledge base is written in. Default English; quotes and the transcript are never translated.
- `power` ("light" | "medium" | "max"): The quality setting. Default `medium`; `light` turns off evidence reconciliation and extraction.
- `max_pointers` (integer): How many still frames the knowledge base may reference, 1 to 50.
- `keep_source_hours` (integer): Keep the recording after the job, so another job can reuse it: 1 to 168 hours, within your organization's cap.
- `references` (object): Supporting material: `transcript` and `notes`, each the id of a completed upload of at most 16 MiB.
- `transcript` (string): The meeting's own transcript; speaker names it carries improve who-said-what attribution.
- `notes` (string): A supporting notes document, in plain text or Markdown.
- `adaptive_evidence_reconciliation` (object): `{"enabled": false}` skips checking each entry against the evidence. Default from `power`.
- `adaptive_evidence_extraction` (object): `{"enabled": false}` captures no frames. Default from `power`.

## Headers

- `Authorization` (string), required: Bearer <API key>
- `X-Operation-Id` (string), required: a unique id you choose, on every call except GET
- `Content-Type` (string), required: application/json, on a call with a body
