Ticketmaster Discovery API vs PredictHQ for AI agents
Ticketmaster Discovery API is a REST API from Ticketmaster for searching events, attractions and venues sold on Ticketmaster and its related ticketing platforms. PredictHQ is a paid event-intelligence API that returns deduplicated real-world events with impact scores, used mainly for demand forecasting.
The short answer
- Ticketmaster Discovery API: Finding concerts, sports and theater events sold through Ticketmaster in North America and Europe, with a direct link to buy.
- PredictHQ: Forecasting demand around events with attendance and impact estimates, rather than sending people to buy tickets.
Side by side
| Ticketmaster Discovery API | PredictHQ | |
|---|---|---|
| Searches | Events, attractions (performers, teams) and venues across Ticketmaster, TicketWeb, Universe, FrontGate, Ticketmaster Resale and other Ticketmaster platforms; paging stops at the 1,000th item. | Events in 19 categories, from concerts, sports, festivals and conferences to public holidays, severe weather and airport delays. |
| Returns | Event name, dates, venue and location, attractions, price ranges, images and the Ticketmaster website URL for the event. | Title, category, start date, location (geometry, address), a 0-100 rank, predicted attendance, predicted event spend in USD and linked entities such as the venue. |
| Before the first call | A Ticketmaster developer account and API key; access to the public APIs is instant after registration. Default quota is 5,000 calls a day (the getting-started page says 5 requests a second, the FAQ says 2). The bulk Discovery Feed and the Partner Commerce API need approval. | A PredictHQ account (sign up for free) and an API token created in the web app. What you can query depends on your subscription. |
| Free | Not stated on its pages | A free trial with no credit card needed; the trial length is not stated. |
| Acting on a result | Ticket link: each event carries its Ticketmaster website URL. Approved affiliates (via Impact) get their tracking added to event links automatically; buying inside your own app needs the restricted Partner Commerce API. | Nothing: the event schema has no ticket or booking link. |
| Limits on keeping or showing results | Event content may be cached or stored only for reasonable periods needed to provide your service, and content must be removed within 24 hours if its owner asks. | Caching, storing or keeping copies of PredictHQ data is prohibited unless you buy the Storage extension or agree otherwise in writing; displaying data requires attribution. |
| AI in its terms | Not stated on its pages | Training or fine-tuning any AI tool, including LLMs, on PredictHQ data, or creating embeddings from it, is prohibited without written authorisation in an Order Form. |
| Coverage | Global; the docs list the United States, Canada, Mexico, Australia, New Zealand, the UK, Ireland and other European countries. | Global. |
| MCP server | No official server listed | Official hosted MCP server at https://mcp.predicthq.com/v1/mcp (OAuth or API key). |
