API integration for data analysis

I am building a data analysis assistant designed to provide structured insights and actionable recommendations based on football data. The assistant will gather data from reliable websites (provided). APIs to deliver accurate and up-to-date analysis on key performance indicators (KPIs) for football matches.

I need a freelance developer to:

Integrate Suitable Sports Data APIs (website sources will be provided)
Configure API Endpoints to fetch specific football historic data
Ensure the assistant receives accurate, real-time statistics
Provide Clear Documentation on how the integration works
