AI agents booking hotels, flights, and car rentals on your behalf are here. MT Travel gives travel merchants an independent, verifiable way to confirm an agent is authorized, within budget, and booking for the right travelers — before confirming the reservation.
A corporate travel AI books a flight. The airline has no way to verify if the company actually authorized this agent, or if the employee is on the approved traveler list.
An agent authorized for hotels books a first-class flight. Without segment-level restrictions, there's no way to enforce travel policy boundaries.
Hotel, flight, and car rental booked separately. No verifiable link between segments. Disputes, chargebacks, and policy violations go undetected.
Every TravelAgentCredential carries a verifiable delegation chain. Each DID in the chain is cryptographically linked, ensuring no unauthorized intermediary can inject itself.
Principal or company requests a TravelAgentCredential from MolTrust. Sets spend limit, segments (hotel/flight/car), cabin class, traveler manifest, and delegation chain. VC is Ed25519-signed.
The travel agent searches for hotels, flights, and car rentals — grouping everything under a single tripId. Presents its DID and TravelAgentCredential at each booking.
Merchant calls MoltGuard /travel/verify. Checks signature, expiry, spend limit, segment authorization, traveler manifest, and trust score. Returns a BookingReceipt anchored on Base.
Hotel + flight + car rental grouped under one tripId. Query all segments with a single API call. Total spend tracked across the entire trip.
Company → HR Manager → Travel Agency → Booking Platform. Each link is a verifiable DID. Spoofed intermediaries can't inject themselves into the chain.
Credential encodes approved travelers with optional passport hashes. Booking for unlisted persons is rejected automatically. No unauthorized side-trips.
Enforce which segments the agent can book (hotel, flight, car) and which cabin classes are allowed (economy, business, first). Policy violations caught at verification time.
Every approved booking generates a BookingReceipt with hash anchored on Base. Tamper-proof audit trail for compliance, dispute resolution, and expense reporting.
Works with any hotel, airline, or car rental API. W3C Verifiable Credential standard — not locked to any OTA or GDS. Any travel platform can integrate.
Before confirming any AI agent reservation, call MoltGuard to verify the agent's TravelAgentCredential. Get a signed booking receipt for compliance and dispute resolution.
A corporate travel AI books hotel + flight for an employee trip to Zurich — verified on-chain via MoltGuard with delegation chain and traveler manifest.
