API software for personal Lego business

Looking for an experienced developer to create API software for my personal Lego business. The main purpose of the API software is to provide price checking and cross referencing functionality.

I am open to different types of API integration, but have not yet determined my preference. The programming language for the API is also undetermined.

Ideal skills for this project would include:
- Proficiency in API development and integration
- Experience with multiple API integration types
- Knowledge of Python, JavaScript, and PHP programming languages

If you have experience in API development and are able to provide recommendations for API integration and programming language, please apply for this project.

I have some information from chat gtp but I am not that experienced with software development. And this is the question I asked.

Can you design code for the following using api

1. Check prices of Lego sets on Amazon AU in a given price range.
2. With the Lego sets found in the given price range use their Lego id number to find the part out price on bricklink using the 6 month average sale pricing
3. Show the difference between the Amazon price and the bricklink part out price as a percentage for all Lego sets searched in descending order
