    Unified REST API for AI media generation at `api.varg.ai/v2`.

    One API key, ~80 models across 8 providers, async jobs, stable output URLs
    on `s3.varg.ai`, files with lineage, and transparent credit billing
    (1 credit = 1 cent = $0.01).

    **The async job pattern:** every generation request returns `202 Accepted`
    with a job object (`status: queued`). Poll `GET /jobs/{id}` until the job
    reaches a terminal status (`completed`, `failed`, or `cancelled`), then read
    `output.outputs[0].url`. Alternatively, set `options.webhook_url` in the
    request to receive an HMAC-signed callback when the job finishes.
