API Introduction

Programmatic access to GC AI for workflow automation

Private Beta. The GC AI API is currently in private beta. To request access, contact your account representative.

Overview

The GC AI External API allows you to integrate GC AI’s legal AI capabilities into your workflows and applications. Perfect for:

• Workflow automation with tools like Zapier, Make, or n8n
• Custom integrations in your internal tools
• Batch processing of legal questions
• Chatbots and assistants powered by legal AI

Current Limitations

The API is currently single-turn only. Each request is independent. Multi-turn conversations are not yet supported.

Base URL

All API requests should be made to:

https://app.gc.ai/api/external/v1

Authentication

All requests require an API key in the Authorization header:

Authorization: gcai_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

API keys are organization-scoped. All requests made with your API key will have access to your organization’s company profiles.

Getting an API Key

In short:

1. An org admin opens Settings → API and enables Allow team to create personal API keys (User API Keys Policy).
2. Each user opens Settings → API → Personal API Keys and clicks + Create API Key.
3. Copy and securely store the key. It is only shown once.

Keep your API key secure. Anyone with your API key can make requests on behalf of your organization.

Quick Start

Here’s a simple example using curl:

curl -X POST https://app.gc.ai/api/external/v1/chat/completions \
  -H "Authorization: gcai_your_api_key_here" \

  -d '{
