# Generate AI hooks for many leads (async batch)

`POST /v1/ai/hook/batch`

Creates an async job that generates a hook for each lead. The create call never charges (`X-No-Charge`); the worker bills 3 credits per successful lead. The `estimatedCost` is an affordability pre-check — insufficient balance for the whole batch returns 402. Poll `pollUrl` for per-lead results.

## Request body

- AiBatchRequest
  - `leads` AiVariableGenerateRequest[], required
    - `leadId` string, uuid, required — The lead to generate for. Must belong to the caller.
    - `locale` string — Output locale (one of the 8 supported locales).
    - `mode` 'native' | 'translate' — `native` generates directly in the target locale; `translate` generates in English then translates.

## Response `200`
