Introduction

DocsRouter is a unified API gateway that simplifies integrating distinct Optical Character Recognition (OCR) and Vision LLM providers into your applications.

Instead of managing multiple API keys, distinct response formats, and separate billing for Google Gemini, OpenAI GPT-4o, Anthropic Claude, and others, DocsRouter provides a single standardized API.

OpenAI SDK Compatible

DocsRouter is fully compatible with OpenAI and OpenRouter SDKs. Just change the base URL:

import OpenAI from 'openai';

const client = new OpenAI({
  baseURL: 'https://api.docsrouter.com/v1',
  apiKey: 'YOUR_DOCSROUTER_API_KEY',
});
