What is RunRelay?
RunRelay is a specialized travel infrastructure designed specifically for AI agents, providing a bridge between complex travel inventories and autonomous workflows. By integrating this into Openclaw Skills, developers can grant their agents access to over 300 GDS airlines and a unique Human-in-the-Loop (HITL) system for low-cost carriers (LCCs) like Ryanair and Wizz Air, which are typically unavailable via standard APIs.
The platform offers a hybrid fulfillment model. It provides instant API results for major carriers and utilizes an asynchronous operator-backed system for budget airlines to ensure 100% market coverage. This makes it an essential tool for building reliable travel concierges, corporate booking bots, and itinerary planners that require more than just standard flight data.
RunRelay Use Cases
- Searching for flights across both major GDS and budget low-cost carriers
- Automating hotel searches and bookings across 700,000+ properties worldwide
- Building autonomous travel agents with Human-in-the-Loop booking capabilities
- Orchestrating multi-agent workflows for simultaneous flight, hotel, and activity planning
- Providing real-time travel status updates and booking management for users
How RunRelay Works
- The AI agent triggers a flight or hotel search request through the Openclaw Skills interface.
- For standard GDS flights, the API returns instant results (Tier 1).
- For low-cost carriers, a Tier 2 request is initiated where human operators assist in fetching live data, which the agent polls via a status endpoint.
- Results are returned with a sorted ranking based on price, duration, and layover quality.
- Upon user selection, the agent submits passenger details to the booking endpoint to finalize the reservation.
- The system provides a unified booking ID and status for tracking and management.
RunRelay Setup
To integrate this capability into your environment, add your API key to your configuration file:
# Add to ~/.openclaw/.env
RUNRELAY_API_KEY=rr_live_your_key_here
You can acquire a live key from the RunRelay developer portal.
