OpenTravel Alliance

The OpenTravel Alliance is a volunteer, non-profit travel technology standards body headquartered in Melbourne, Florida, United States. Since 1999 it has published the OpenTravel Specification — the OTA 1.0 XML message suite (releases 2001A through 2024A) and the model-driven OpenTravel 2.0 Object Model (OTM), which generates XML Schema, JSON Schema and Swagger 2.0 resource contracts — plus the OpenTravel Code Lists used across air, hospitality, car rental, cruise, rail, GDS, channel and technology-provider systems. OpenTravel does not operate a booking service or sit in the distribution chain itself; it supplies the message vocabulary that suppliers, GDSs, channel managers and OTAs implement between each other, which makes it a switching-cost reducer rather than a switching-cost holder. Its API posture is honest but thin: there is no OpenTravel-operated runtime API and no public certification registry, though it does run a free self-serve developer portal — the OpenTravel Developers Network at opentraveldevelopersnetwork.com — and, as of 2026, an OAuth 2.1 protected Model Context Protocol server on opentravel.org. Specifications are royalty-free and free of charge, but the canonical download is behind a name/company/email lead-capture form with terms acceptance, and the OTM repository and member review periods are membership-gated ($950–$11,250/yr by revenue band). A public, unlicensed GitHub mirror at github.com/OpenTravel/OpenTravel-Specifications carries the bulk of the corpus — including eight Swagger 2.0 resource contracts — and is the only ungated route to machine-readable artifacts. The organization has announced work with the Linux Foundation to form an Open Travel Foundation.

OpenTravel Alliance publishes 6 APIs on the APIs.io network, including Facilities API, Hospitality Find Hospitality Availability API, Hospitality Offers API, and 3 more. Tagged areas include Travel, United States, Standards, Aviation, and Hospitality.

The OpenTravel Alliance catalog on APIs.io includes 1 event-driven AsyncAPI specification.

OpenTravel Alliance’s developer surface includes getting-started guide, support, authentication, changelog, CLI, code examples, API reference, and 55 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/opentravel-alliance: open an issue to ask a question, or submit a pull request to add artifacts.
