SeatGeek vs Ticketmaster

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.

Ticketmaster's Discovery API v2 (base host app.ticketmaster.com) returns JSON search results for events, attractions, and venues, authenticated with a free API key (a "Consumer Key") issued from a developer account. Every key starts on the default public quota of 5,000 calls/day at up to 5 requests/second, tracked via Rate-Limit response headers, with higher volume available case-by-case on request rather than through any published paid self-serve tier. Deep paging is capped at the 1,000th result per query, per the API's own documented limits.
