Add algorithm to current source code that generates a numerical score as a layer onto an image

Code has to grab data from an API and quantify them based on the information received - all of these factors will then be given different weights and then used to create a final score out of ten.

For example the first factor could be number of transactions ( Available via API)
Second factor would be number of social mentions ( Available via API)

There would be a few more factors all used to calculate final score example: 8.3/10

Final score must then be added to existing image as a layer, and overall image converted and stored on server as a png image.
