## Overview

This repository is an Express API gateway exposing Pollinations-backed text, image, and audio features, including OpenAI-compatible model and chat endpoints. The main workflow is an API client request reaching a route, which validates and dispatches it to Pollinations before returning a response. The sampled source shows those route and provider interactions; frontend behavior and other omitted implementation details are not inferred.

Main entry points: [`index.js`](https://github.com/fikrifahrezi25/exodusapi/blob/main/index.js) (Express routes)
