name: EventX
description: EventX (EventXtra Limited) is an AI-powered, all-in-one event management and marketing platform for in-person,
  virtual, and hybrid events, headquartered in Hong Kong with offices across APAC. It provides event registration and RSVP,
  QR-code check-in and badge printing, ticketing and payment with 0% platform fees, AI Lead Finder, event website building,
  virtual event hosting, sponsor and exhibitor management, lead capture, and WhatsApp/email marketing. EventX serves 5,600+
  brands and is ISO 27001 certified and GDPR compliant. It also offers an official hosted MCP server that lets AI assistants
  query live event data (registrations, sessions, ticket sales, attendance) in natural language, provisioned one-click from
  the EventX dashboard and compatible with Claude, ChatGPT, Cursor, and OpenCode. EventX publishes a REST Public API documented
  as an OpenAPI 3.2.0 contract (46 paths, 58 operations) at esaas-api.eventx.io, covering events, attendees, custom fields,
  ticket classes, orders, invoices, media, registration forms and outreach, plus a per-event webhook subscription API delivering
  five attendee lifecycle actions. Added to the API Evangelist network as a portfolio company of 500 Global and enriched via
  the pipeline.

  note: The OpenAPI and the full API reference are anonymously readable, and the platform itself has a free self-service tier.
    The apiToken that POST /public-api/v1/auth requires is listed on the pricing page as an Enterprise-plan-only entitlement,
    so no self-service developer can obtain API credentials.

- name: EventX Public API
  description: The EventX Public API is a REST interface over the EventX event management platform, published as an OpenAPI
    3.2.0 document with 46 paths and 58 operations across Auth, Event, Attendee, Custom Field, Event Webhook, Order, Outreach,
    Ticket Class, Invoice, Media, Registration Form, Registration Service, Registration Order, Salesforce and organization-scoped
    custom domains. Authentication is an apiToken-for-JWT exchange (POST /public-api/v1/auth) with the resulting bearer token
    sent in an Authorization header. Listing operations share a page/pageSize envelope with a { dataList, pagination } response,
    and a per-event webhook subscription API delivers five attendee lifecycle actions. The specification and the reference
    documentation are anonymously readable; the apiToken itself is an Enterprise-plan entitlement.

  note: Round 2 found the machine-readable contract round 1 missed. The EventX OpenAPI 3.2.0 is served at https://esaas-api.eventx.io/api-docs/public-api/openApi.json,
    linked only from the GitBook knowledge base at eventx-hq.gitbook.io (the marketing site has no developer section and its
    sitemap names no API page).
