Helix for platforms · White label · Widget · API · MCP
The booking layer for travel brands and AI agents.
Helix turns a plain-language request into a confirmed flight, hotel or event booking, with preferences, rules and payment handled. Run it under your own brand, embed it in your site, or connect your own agent to it.
Ways to build on Helix
One engine, five ways in
Put Helix under your brand, inside your site, or behind your own agent. Early-access partners on the booking API and MCP server are set up in days, around their use case.
White label
Run the Helix assistant as your own product, on your domain, with your logo, colours and emails.
- Your brand on web and in email
- Your payments account
- Per-brand guardrails, tested before launch
Bring your own keys
Book on your own supplier contracts and pay the supplier directly. Helix adds no margin to those bookings.
- Flight, hotel and payment accounts
- Your own AI model keys
- Each key approved before it goes live
Embeddable widget
Put Helix inside your own site with one script tag, so customers never leave your page.
- Inline or overlay
- Single sign-on from your site
- English, French, German, Dutch and Spanish
Booking API
A versioned API to search, hold, book and manage trips from your own product, with no Helix interface.
- Search, book, change and cancel
- Preferences and rules applied server-side
- Partner keys and usage reporting
MCP server
Helix search and booking exposed as Model Context Protocol tools, so any MCP-capable agent can complete a booking.
- Flights, hotels and events as tools
- Confirmation returned to the agent
- Works alongside the booking API

Request early accessFor personal AI agents
Your agent can plan the trip. Helix can book it.
Personal agents are getting good at knowing what their users want. Turning that into a ticketed flight or a confirmed room still takes supplier contracts, payments, fare rules, changes and cancellations. That is the part Helix already does, every day, for its own products.
The booking API and MCP server put that engine behind your agent. Your agent keeps the relationship with its user; Helix completes the booking and handles what happens after it.

The same engine that runs Helix Business and Helix Black
Whichever way you connect, your customers or your agent get the full booking engine.
Flights
Search, book, seats, bags and extras, then changes and cancellations in the same thread.
Hotels
Global hotel inventory with live availability, shortlisted rather than listed.
Events and activities
Tickets and activities, with a whole trip built around the event.
Preference memory
Helix learns how each person travels, and they can see and change what it has learned.
Rules while it searches
Budgets, policies and approvals are applied during the search, not after the booking.
Money handled in code
Pricing, payment and booking run in deterministic code. No language model sits between a choice and the supplier.
Chat and voice
Type or speak a request. Both run on the same engine.
People when needed
Requests that need judgement can escalate to a concierge team with the full context.
Who builds on Helix
Built for the businesses that own the customer
Personal AI agents and assistants
Your agent already knows what its user wants. Helix lets it finish the job: a ticketed flight, a confirmed room.
Travel management companies
Offer your corporate clients AI booking under your own brand, on your own supplier contracts.
Online travel agencies
Add a conversational booking layer on top of the supply you already have.
Event and destination operators
Turn an audience travelling to an event or a place into bookings, under your brand.
Running a members' programme, private bank or premium card? Helix Black is built for you.
