Overseas Connects: API
One API.
The entire travel stack.
Overseas Connects gives your platform direct, programmatic access to vetted global inventory — hotels, experiences, transfers, and car rental — with real-time availability, instant booking, and the infrastructure to scale.
Why Overseas Connects
Not just an API. A travel partner.
Vetted inventory
Every property in our network is hand-selected. Not an aggregator dump. We know what we're selling and we stand behind it.
Zero intermediaries
Direct contracts with suppliers. No extra layer, no hidden markup. You get the rate, you control the margin.
Competitive rates
Direct supplier relationships mean real pricing advantages over public OTA rates, passed through to you and your customers.
Beyond tech, we pick up the phone
27 years of operational expertise behind every API call. When something goes wrong, a human being from our team handles it. End to end.
The API
Clean endpoints.
Instant results.
A single availability request returns real-time inventory, room types, rates, and instant booking confirmation across your target properties.
