Demio

Demio is a browser-based webinar and virtual-event platform built for B2B marketing and sales teams, operated by Banzai International, Inc. (NASDAQ: BNZI). It runs live, automated/evergreen, on-demand and series webinars with no attendee download, and pairs them with customizable registration pages, embeddable registration forms, in-session engagement tools (polls, handouts, featured actions, chat), recordings, Showcase event listings and post-webinar analytics. Its public developer surface is the Public Demio API — a key/secret authorized REST API at https://my.demio.com/api/v1 covering Events, Event Sessions (Dates), attendee registration with unique join links, and per-Session participation reporting. Demio documents the API as an Apiary API Blueprint, publishes burst rate limits and daily call quotas, runs a public Atlassian Statuspage, ships one first-party PHP SDK from its meetdemio GitHub organization, and offers a Zapier app with registration, join, no-show and event-update triggers for teams that do not want to call the API directly.

Demio publishes 3 APIs on the APIs.io network: Events API, Intro API, and Reports API. Tagged areas include Company, Webinars, Virtual Events, Event Management, and Marketing.

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

Demio’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 30 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/demio: open an issue to ask a question, or submit a pull request to add artifacts.
