# Overview

Learn how to use the Helvia.ai API

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

### Services

| Service               | Description                                                                                                                                 |
| --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- |
| **hbf-bot**           | Runs agent configurations in real-time chat channels such as Web, Viber and Teams                                                           |
| **hbf-doc-ingestion** | Ingests documents (PDF, DOCX, PPTX, HTML, MD, TXT), converts them 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
