Text to Image

How to Generate Images using the OneRouter API

To generate images using the OneRouter API, you need to send a request to the appropriate endpoint with the desired input parameters. The API uses pre-trained models to generate images based on the provided text prompt. This allows you to create images by simply describing what you want in natural language.

Here’s an example of how to generate an image using the OneRouter API from text:

Curl

curl https://image.onerouter.pro/v1/images/generations \
    -H "Content-Type: application/json" \
    -H "Authorization: <API_KEY>" \
    -d '{
    "model": "gpt-image-1",
    "prompt": "A cute baby sea otter",
    "n": 1,
    "output_format": "url"
  }'

Python

• https://image.onerouter.pro/v1/images/generations is the base URL

• <API_KEY> is your API Key generated in API page.

• model is the model name, such as gpt-image-1, available model list can be access in Model page.

• prompt is the prompt.

• n is the number of images to generate, default value is 1.

• output_format indicate the output format, default value is url.

  • b64_json

  • url

You can find more models and their descriptions in the Model page.
