1World Online

1World Online is an audience-engagement and interactive-advertising company, operating since 2012, that serves media publishers, advertisers and travel brands. Its platform embeds Interactive Media Units — polls, quizzes, trivia, debates and surveys — into publisher pages in 30+ languages, turns the resulting engagement into interactive ad inventory and first-party audience insight, and rewards participants through a points-based loyalty program and Web3 collectables (TravelVerse). The company also operates a technology center offering custom development and integration services. Its platform backend is live at app-wleu.1worldonline.com and serves the publisher portal, widget frontend and loyalty applications, but 1World Online publishes no public developer portal, API reference or machine-readable contract today, and the historic public Swagger UI host api.1worldonline.com no longer resolves.

1World Online publishes 1 API on the APIs.io network. Tagged areas include Advertising, Audience Engagement, Polls, Surveys, and Quizzes.

1World Online’s developer surface includes support, signup flow, engineering blog, YouTube channel, and 12 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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/1worldonline: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: 1World Online's platform backend is live at app-wleu.1worldonline.com and its own frontend configuration names it,
    but the only route to it is the publisher/advertiser partner registration SPA at frontend-wleu.1worldonline.com — the
    formerly public Swagger UI host api.1worldonline.com no longer resolves in DNS, and the live backend returns 404 for every
    conventional specification path.
