How to AI Analyze and Compare Multiple Images with the Screenshot API

Learn how you can use the Screenshot API to automatically analyze, compare, and contrast multiple images with PagePixels' built-in AI analysis capabilities.

Introduction

PagePixels' Screenshot API can help you analyze, compare, and extract insights from multiple screenshots and other images.

To accomplish this, you can use the Screenshot API's Multiple Image AI Analysis endpoint. This endpoint can send up to 5 images and 5 custom text prompts to OpenAI (creators of ChatGPT) for AI visual analysis at one time.

  • An image can be a direct link to a screenshot or any PNG, JPEG, WEBP, or GIF image file up to 20MB in size.
  • A prompt can refer to any image, compare multiple images, and be up to 2000 characters.
  • Each prompt and each image submitted for analysis uses 1 AI Analysis Credit. For instance, the example in this tutorial uses 5 AI Analysis credits to analyze 2 images and 3 prompts.

AI Analysis functionality is ready to go in PagePixels. No OpenAI keys are required, and all PagePixels accounts get 25 FREE AI Analysis credits per month.

This tutorial provides an example of how you can use the Multiple Image AI Analysis endpoint to analyze and compare two images guided by three prompts.

How to analyze and compare multiple images using the Screenshot API

To analyze and compare multiple images using the Multiple Image AI Analysis endpoint of the Screenshot API:

1

Get your API Key

You can access your API Key in two locations:

  • While signed in, go to the Authentication section of the API documentation. Copy the Private API Key value.
  • Or click on "Profile" in the right sidebar, navigate to "API Keys", and copy the Private API Key value.
2

Run AI Analysis

POST
/ai/analyze 


$


curl -X POST "https://api.pagepixels.com/ai/analyze?access_token=your-api-key" \
-H "Content-Type: application/json" \
-d '{
  "urls": [
    "https://cdn.pagepixels.com/15e416bf-44fc-4c11-a58c-a539b1d29abb/f116729e0d400d-1735569001008.jpg",
    "https://cdn.pagepixels.com/15e416bf-44fc-4c11-a58c-a539b1d29abb/1d956cf59ece00-1735309803108.jpg"
  ],
  "prompts": [
    "Please describe the second image.",
    "Please describe the first image.",
    "Compare and contrast the two images."
  ]
}'

Make a POST request to the ai/analysis endpoint to run an AI analysis on multiple images.

Copy the example above and replace the value of the access_token with your API Key.

Update the values in the urls and prompts arrays with the direct links to the images you want to analyze and the prompts you would like to use.

Once updated, paste the request into your terminal and press enter.

Note: cURL must be already installed for this to work.
