Eventbrite vs SeatGeek

Eventbrite's Platform API (v3, base host www.eventbriteapi.com) is built around managing an organizer's own events rather than searching the wider Eventbrite catalog: creating and updating events, defining ticket classes and pricing, and reading orders and attendees, all authenticated with OAuth 2.0 (a private token for your own account, or the full authorization-code flow for apps acting on behalf of other users). The public event-search endpoint was retired in 2019 — a live request against it now returns a plain 404 rather than search results. Access is included with any Eventbrite account at no extra API charge; no separate self-serve paid tier is published.

SeatGeek's Platform API returns JSON data on live events, performers, and venues across the US — including average ticket prices and venue geolocation — authenticated with a free client_id issued from a SeatGeek account. A live unauthenticated request against api.seatgeek.com/2/events returned SeatGeek's own "Client is required" error while still reporting a 100-requests-per-minute rate-limit ceiling in its response headers, confirming the API is reachable and free to register for without any paid tier. Its Platform Terms of Use prohibit reselling or displaying raw ticket listings from other sellers, restricting use to building on SeatGeek's own event data rather than a general ticketing aggregator.
