Overview

## What API Lessons does

API Lessons is an index of short, free Lightning Lessons hosted on the Maven platform. Subjects covered are APIs, MCP, product management, careers in technical product management, and ChatGPT apps.

For any listed lesson there are three paths: watch a past recording, register for an upcoming live session, or find the longer cohort based course that goes deeper into the same subject. Sessions run over Zoom, are practical in focus, and are held in English only.

The lessons are taught by Emmanuel Paraskakis, an entrepreneur and product management consultant at Level 250 with more than fifteen years of work shaping products. The stated audience is mid career professionals in software and technology.

### Who it is for

Mid career product and technical staff looking for short sessions on APIs, MCP, or product management.

### What stands out

It connects each short lesson to the longer course that covers the same ground.

## Where API Lessons is listed

API Lessons is listed in the ChatGPT apps directory only. Level 250 Inc. has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
