Eventory exposes four APIs through a single gateway at https://api.eventory.ai. They share one API key, one error format, and one credit balance, but they answer different questions.

The four APIs

Notifications API

A WebSocket that pushes a notification the moment an event on your watchlist changes: stock appears, a price drops, a new section opens. Not included in API plans: access is granted separately to a limited number of partners.

Watchlist

Create, read, update and delete the events you want the Notifications API to watch. Free with your plan.

Live Availability

Ask for the current inventory of any single event on Ticketmaster, AXS, Eventim, StubHub, viagogo and seven more platforms, right now. 5 credits per call.

Market Data

Historical sales, price history, aggregate statistics, artist social metrics and full-text search over the Eventory catalog. 1 credit per call.

Which one do I need?

The Notifications API and the Live Availability API share the OfferSections and SeatMapSections shapes, so a client that parses one can parse the other; the stream also sends EventDiscovery for discovery monitors. See Section types.

What you need to know first

1

Get a key

Keys are issued with an Eventory plan. Every request carries it in the apikey header. See Authentication.
2

Know what your key can call

Each key is granted a set of APIs. The watchlist and /usage come with every plan; Market Data and Live Availability are enabled per account. The Notifications API is not part of any plan: access is granted separately to a limited number of partners. See Credits & access.
3

Make your first call

GET /usage is free, works with any valid key, and tells you your plan and remaining credits. Start there in the Quickstart.
