# Procurize.AI REST API Reference

**Programmatically access your knowledge base – documents, questionnaires, RAG, and reports – using your API token.**

> **Applies to:** Procurize.AI API v1  
> **Authentication:** API key via `X-API-Key` header (see [API Tokens](/api-tokens/) for token management)  
> **Base URL:** `https://api.procurize.com`

## Overview

The Procurize.AI REST API provides programmatic access to key platform features. It enables you to integrate Procurize.AI with your internal systems, automate knowledge base management, and build custom workflows.

**Supported modules (token‑authenticated):**

- [**RagArticle**](#ragarticle) – manage documents
- [**RagFaq**](#ragfaq) – manage FAQ entries
- [**RagQuery**](#ragquery) – execute RAG queries

## Authentication

All authenticated endpoints require an API token passed in the request header.

| Header | Value |
|--------|-------|
| `X-API-Key` | `<YOUR_API_TOKEN>` |

**Example:**
```bash
curl -X GET "https://api.procurize.com/v1/..." \
  -H "X-API-Key: your-api-token-here"
```

> 💡 Tokens are bound to your organization – you do not need to specify an organization ID in the request .

## Base URL

All REST API endpoints are served under:
```
https://api.procurize.com
```

## Error Handling

The API uses standard HTTP status codes.
