PredictHQ vs Eventbrite API for AI agents
PredictHQ is a paid event-intelligence API that returns deduplicated real-world events with impact scores, used mainly for demand forecasting. Eventbrite API is Eventbrite's REST API (v3) for working with events, orders, attendees and organizations on Eventbrite.
The short answer
- PredictHQ: Forecasting demand around events with attendance and impact estimates, rather than sending people to buy tickets.
- Eventbrite API: Managing your own Eventbrite events or reading events from venues and organizers whose IDs you already know; not for open discovery.
Side by side
| PredictHQ | Eventbrite API | |
|---|---|---|
| Searches | Events in 19 categories, from concerts, sports, festivals and conferences to public holidays, severe weather and airport delays. | No public event search: the Event Search endpoint was shut down in December 2019. You can fetch an event by ID and list events by venue ID or organization ID. |
| Returns | 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. | Event records retrieved by event ID, or paginated lists of events for a known venue or organization. |
| Before the first call | 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 | A free trial with no credit card needed; the trial length is not stated. | – |
| Acting on a result | Nothing: the event schema has no ticket or booking link. | – |
| Limits on keeping or showing results | 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 | 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. | – |
| MCP server | Official hosted MCP server at https://mcp.predicthq.com/v1/mcp (OAuth or API key). | – |
