Getting Started

This guide walks you through setting up your Coldreach API key and making your first API request.

Authentication

All API requests require an API key passed in the x-api-key header.

You can find your API key in the Coldreach dashboard under Settings > API.

curl -H "x-api-key: YOUR_API_KEY" \
  https://api.coldreach.ai/public/v1/auth

A successful response confirms your key is valid:

{
  "signed_in": true
}

All API endpoints are available at:

https://api.coldreach.ai/public/v1

API requests are logged and monitored. Contact us if you need higher rate limits for your integration.
