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

Real-time stream

A WebSocket that pushes a notification the moment an event on your watchlist changes: stock appears, a price drops, a new section opens. Free with your plan.

Watchlist

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

Live Availability

Ask for the current inventory of any single event on Ticketmaster, AXS, Eventim, StubHub, viagogo and six 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 stream and the Live Availability API return the same sections shapes, so a client that parses one can parse the other. 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 stream, the watchlist and /usage come with every plan; Market Data and Live Availability are enabled per account. 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.
