`POST https://api.border.bot/v1/classify/batch`

Requires an API key (`Authorization: Bearer bb_live_…`).

Each item is a classify request, run four at a time and charged as one classification by its own mode; one failing (an unclassifiable description, insufficient credits) never stops the others and is refunded. With an `Idempotency-Key`, each item replays on its own.

API key scope: `classify`.

## Headers

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `idempotency-key` | string | no | Make retries safe: a repeat with the same key returns the original result without charging again (keys are scoped to your workspace). |

## Request body (JSON)

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `items` | ClassifyRequest[] | yes |  |
