    Properties

    apiKey?: string

    Google AI API key. Default: process.env.GEMINI_API_KEY.

    baseURL?: string

    API base. Default: "https://generativelanguage.googleapis.com/v1beta".

    fetch?: {
        (input: URL | RequestInfo, init?: RequestInit): Promise<Response>;
        (input: string | URL | Request, init?: RequestInit): Promise<Response>;
    }

    Injectable fetch (default: global fetch).

    Type Declaration

      • (input: URL | RequestInfo, init?: RequestInit): Promise<Response>

      • MDN Reference

        Parameters

        • input: URL | RequestInfo
        • Optionalinit: RequestInit

        Returns Promise<Response>

      • (input: string | URL | Request, init?: RequestInit): Promise<Response>

      • MDN Reference

        Parameters

        • input: string | URL | Request
        • Optionalinit: RequestInit

        Returns Promise<Response>

    maxRetries?: number

    Retries on transient errors (503/429/500). Default 4 (exponential backoff).

    mimeType?: string

    Override the image mime type sent to the model (else the challenge's).

    model?: string

    Model id. Default: "gemini-3.1-flash-lite".

    prompt?: string

    Instruction sent alongside the image.

    rasterize?: (
        challenge: CaptchaChallenge,
    ) => Promise<{ data: Uint8Array; mimeType: string }>

    Convert the challenge image to a Gemini-supported raster (PNG/JPEG/WEBP). Gemini vision rejects image/svg+xml, and the tutti captcha is an SVG — supply a rasterizer (e.g. a small SVG→PNG step) to auto-solve it.
