# OCTO - Open Connectivity for Tours, Activities & Attractions > OCTO is a non-profit trade body that provides an open API specification for the tours, activities, and attractions industry. The OCTO standard enables technology platforms — booking systems, resellers, channel managers, and marketplaces — to connect with each other through a single, shared integration rather than building custom point-to-point connections. ## What OCTO Does OCTO solves the fragmentation problem in tours and activities distribution. Without a standard, every booking platform must build and maintain separate integrations with every other platform. OCTO provides one open API spec that any platform can implement, dramatically reducing integration cost, time, and maintenance. ## Key Facts - The OCTO specification is open-source and free to implement — no membership required - Membership starts at $199/year and provides support, tooling, and community access - OCTO has 80+ member organizations including major booking platforms and tour operators - The standard covers availability, booking, pricing, and fulfillment for tours and activities - OCTO is governed by an elected Board of Directors and member-powered committees ## Membership Types - **Technology Member**: For platforms that implement the OCTO API (booking systems, resellers, OTAs, channel managers). These companies build integrations using the specification. - **Industry Member**: For operators, DMOs, tourism boards, and businesses that benefit from OCTO-powered connectivity but do not implement the API themselves. ## Pages - [Home](https://octo.travel/): Overview of the OCTO standard and its value - [About](https://octo.travel/about.html): What OCTO is, the problem it solves, and how it works - [Membership Plans & Pricing](https://octo.travel/membership.html): Technology and Industry plans starting at $199/year - [For Industry Members](https://octo.travel/industry-members.html): Benefits for operators, DMOs, and non-technical businesses - [For Tech Partners](https://octo.travel/tech-partners.html): Benefits for platforms implementing the API - [Get Involved](https://octo.travel/get-involved.html): Committees, spec review, and community participation - [What's New](https://octo.travel/whats-new.html): Specification updates, governance news, and community highlights - [Member Directory](https://octo.travel/members.html): Browse all OCTO member organizations - [Specification](https://octo.travel/specification.html): The open API specification (free, no membership required) - [Governance](https://octo.travel/governance.html): Board of Directors, Advisory Board, and Spec Committee - [Contact](https://octo.travel/contact.html): Get in touch with the OCTO team ## Specification The OCTO API specification is hosted on GitHub and is free to use.
