# Overview

The Helvia.ai Platform exposes REST APIs through multiple services. Each service handles a specific domain of the platform's functionality.

### Services

| Service               | Description                                                                                                                                                  |
| --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **hbf-bot**           | Chatbot executor — runs agent configurations in real-time chat channels (Web, Viber, Messenger, Slack, Teams). No OpenAPI spec.                              |
| **hbf-doc-ingestion** | Document processing — ingests documents (PDF, DOCX, PPTX, HTML, MD, TXT), converts to Markdown, segments into semantic chunks, and optionally tags via LLMs. |

### Common Patterns

All API services follow these conventions:

* **Content-Type**: `application/json` for request and response bodies
* **Error responses**: Standard HTTP status codes with JSON error bodies
* **CORS**: Enabled for all origins in local development
