Complete guide to using grok-imagine
Modify and restyle any reference image using natural language via the grok-imagine/image-to-image endpoint on ApiPass. Simply upload a JPEG, PNG, or WebP file along with your text prompt to initiate an asynchronous generation task. This developer-friendly API seamlessly handles everything from subtle edits to complete artistic overhauls.
The Grok Image-to-Image workflow utilizes one uploaded reference image and a targeted text prompt to generate a transformed image asset. It is engineered for enterprise visual remixes, style transfers, character reinterpretation, programmatic layout overhauls, high-end product placement, and rapid automated prototyping.
Describe the visual change you want and use one reference image as context. The prompt can specify subject changes, lighting, composition, mood, style, background, text treatment, or commercial art direction.
The image_urls parameter accepts an array of file URLs, but this endpoint supports a maximum of one reference image per request. Supported reference formats are JPEG, PNG, and WebP, with a maximum size of 10MB per file.
Create a task with POST /api/v1/jobs/createTask, store the returned taskId, and query results with GET /api/v1/jobs/recordInfo. You can also provide callBackUrl to receive completion or failure updates automatically.
Use detailed prompts to guide the generated image toward a specific look, mood, scene, or composition. The endpoint is useful for turning a simple reference into a more polished visual concept.
Upload one image as the source reference and point to it with @image1 inside the prompt. This keeps the request clear and helps the model understand which visual input should guide the output.
The API is built around asynchronous task creation. Submit the job, receive a taskId, and retrieve results later through the query endpoint or a callback URL when the task completes.
Transform a reference image into a poster-style composition with dramatic lighting, refined typography direction, stylized characters, or a polished entertainment concept.
Create premium product-style mockups, visual variations, background changes, or concept imagery from a single input image for fast iteration in design and marketing workflows.
Reimagine people, pets, mascots, or illustrated subjects in new styles while using the uploaded image as the visual reference for the generated result.
Choose the right ApiPass workflow based on whether you start from text, a still image, or a motion output.
Text-to-image starts from a prompt only, while image-to-image starts from an uploaded reference image plus an optional prompt. Use image-to-image when the source composition, subject, or visual direction should influence the generated result.
Image-to-image produces a generated still image. Image-to-video workflows are used when you want to animate a still reference into motion. For this endpoint, the output is an image and the supported input is one reference image URL.
ApiPass uses a credit-based access model for generation tasks. Review your dashboard for the latest credit usage, channel availability, and account limits before moving into production.
The optional channel parameter supports auto, starter, regular, and official. The default auto channel lets ApiPass allocate tasks across available providers based on real-time pricing and stability metrics.
New users may receive free credits to test image-to-image generation in the ApiPass playground before building a production integration.
Upload a JPEG, PNG, or WebP reference image with the File Upload API. The image must be 10MB or smaller. Use the returned file URL in the image_urls array.
Send a POST request to /api/v1/jobs/createTask with model set to grok-imagine/image-to-image and input containing image_urls and prompt. In the prompt, reference the uploaded image with @image1 followed by a space.
Store the taskId returned by the create task endpoint. Query /api/v1/jobs/recordInfo?taskId=YOUR_TASK_ID until the task succeeds, or provide callBackUrl to receive completion or failure notifications automatically.
All APIs require authentication via Bearer Token.

image_urlsRequiredarray<string>An array of URL strings pointing to reference images. Use file URLs after upload, not raw file content. Accepted image types are image/jpeg, image/png, and image/webp. Maximum file size is 10MB per image.
Upload your reference image with the File Upload API first, then use the returned file URL in image_urls. This model supports a maximum of one reference image per request, even though the upload control may allow multiple files.
