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, Reports API, and Intro 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.
