Alexandre Leonardi authored the IOC Upload API Documentation for the SEKOIA-IO/documentation repository, focusing on improving API discoverability and streamlining client integrations. He detailed the endpoint and payload structure, including both default fields and per-indicator specifics, and provided a Python usage example to illustrate practical implementation. Leveraging skills in API documentation, technical writing, and threat intelligence, Alexandre used Markdown and JSON to ensure clarity and precision. The documentation included a comprehensive response schema, directly linked to the relevant commit for traceability. This work reduced onboarding time for developers integrating IOC uploads, demonstrating thoroughness and attention to integration challenges.
