OAG scores A on the API Report Card. OAG's Flight Info REST APIs are self-serve at developers.oag.com: schedules, status, connections, and push alerts, fronted by Azure API Management with subscription-key auth.

OAG has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
OAG (Official Aviation Guide) is the world's longest-running aviation data provider, founded in 1929 as a printed flight-schedule directory and today operating as the schedules-of-record authority for the global travel-distribution ecosystem.
Primary vertical: misc - Fleet / Trucking / Logistics (specifically the aviation/travel data layer; no native Supergood vertical maps perfectly, with Travel & Expense and POS/Hospitality as secondary neighbors for the corporate-booking and hotel-arrival use cases). A GDS or OTA ingests OAG schedules nightly (or via near-real-time refresh) as canonical input to its low-fare-search, connections-building, and timetable-display surfaces - then layers airline-direct NDC and live availability on top at shop time.
High inside aviation, travel distribution, airline IT, parametric insurance, and financial-analytics workflows; lower among indie developers and SaaS prototypers.
Yes - OAG's Flight Info API and enterprise data feeds sit directly in the operational path of any travel, hospitality, aviation, financial-analytics or parametric-insurance system that depends on accurate schedules, flight status, connections, or airfare data.
96 years old (founded 1929 in Chicago as the Official Aviation Guide of the Airways - inaugural February 1929 issue listed 35 airlines operating 300 flights).
Azure APIM subscription-key auth (header-based but a single shared secret per subscription) leaks into nginx, CloudFront, Datadog and any logging layer that captures full headers - mishandled keys are a recurring enterprise-integration concern. OAG explicitly tells developers not to enable CORS / not to call the API from the browser because the subscription key would leak - this forces every integrator to stand up a server-side proxy even for trivial dashboards.

Common alternatives include Cirium (FlightStats, Innovata, Diio, Ascend - RELX), FlightAware (Collins Aerospace / RTX), Flightradar24, AviationStack, Aviation Edge, AeroDataBox. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
