EventX
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.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles EventX the way a machine reads it — 23 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — EventX scores 55.8/100 (strong), with a separate agent-readiness read of 36/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile EventX
Each block below is one kind of artifact we hold for EventX. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 15
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
EventX Attendee API
The Attendee API from EventX — 9 operation(s) for attendee.
EventX Auth API
The Auth API from EventX — 1 operation(s) for auth.
EventX Custom Field API
The Custom Field API from EventX — 2 operation(s) for custom field.
EventX Event API
The Event API from EventX — 4 operation(s) for event.
EventX Event Webhook API
The Event Webhook API from EventX — 3 operation(s) for event webhook.

MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

RATE LIMITSEvent Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.
AsyncAPI definitions for this provider's event-driven and streaming APIs.

ASYNCAPISecurity Posture 3
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of EventX, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
