AGL

AGL Inc. (에이지엘) is a Seoul-headquartered golf technology company, founded in 2019, that operates TIGER GDS — a global distribution system for golf. Its SaaS platform connects golf club tee-time inventory to travel and booking channels in real time, covering more than 1,000 contracted golf courses across 30+ countries, and is the system behind the HeyTeeTime/TIGERBOOKING consumer apps and the Reserve with Google golf integration. AGL publishes three machine-readable REST contracts on tigergds.com: the AGL OTA API (distribution — code lookups, golf club catalog, tee-time availability, static packages and the full reservation lifecycle), the AGL OPEN API (a bi-directional supplier bridge for golf-club and tee-time registration plus reservation callbacks) and a Trip.com outbound reservation integration. Offices in Seoul, Tokyo, Brea (CA) and Singapore.

AGL publishes 3 APIs on the APIs.io network: OTA API, OPEN API, and Trip.com Reservation Integration API. Tagged areas include Company, Golf, Travel, Booking, and Reservations.

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

AGL’s developer surface includes authentication, documentation, API reference, support, engineering blog, signup flow, and 23 more developer resources.

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.

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/agl: open an issue to ask a question, or submit a pull request to add artifacts.
