    **Authentication:** `Authorization: Bearer f0_live_*` or `alk_live_*` API
    keys (write or read scope).


    **Async ingest (default):** POST ingest endpoints return `202 Accepted` with
    a `receipt_id`.

    Poll `GET /v1/receipts/{id}` until `status` is `committed` or `failed`.

    Force synchronous ingest with header `X-Fact0-Sync: true`  or query
    `?sync=true`.
