Quick Start 🚀

💡 In summary, you only need to do two things: apply for an API Key and configure it in your AI assistant. No coding required – any MCP-compliant AI assistant gains hotel search capabilities in 5 minutes with your first tool call.

Step 1: Get Your API Key

1. Visit the Application Page

2. Fill in basic information – automatic approval within 1-3 minutes. You'll receive an email containing:

   • API Key

   • Partner Center account (login + initial password) to configure markups, view orders, and check earnings

3. ⚠️ Check your email (including spam folder) for the API Key

4. Limited-Time Offer: All developers who complete their first tool call within 3 days of receiving the API Key unlock permanent unlimited free access. We prioritize developers with real needs and execution speed, offering zero-cost access to complete hotel MCP capabilities.

The email includes both hotel and flight MCP endpoints – 1 key for both.
