SerpApi Google Events API vs PredictHQ for AI agents
SerpApi Google Events API is a paid API that scrapes Google's events results and returns them as JSON. PredictHQ is a paid event-intelligence API that returns deduplicated real-world events with impact scores, used mainly for demand forecasting.
The short answer
- SerpApi Google Events API: Broad event discovery across many ticket sellers by reusing Google's events results.
- PredictHQ: Forecasting demand around events with attendance and impact estimates, rather than sending people to buy tickets.
Side by side
| SerpApi Google Events API | PredictHQ | |
|---|---|---|
| Searches | Whatever Google's events results show for a query and location: concerts, sports, local and community events. | Events in 19 categories, from concerts, sports, festivals and conferences to public holidays, severe weather and airport delays. |
| Returns | Title, date, address, venue name and link, ticket sources with links, and a thumbnail. | 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 SerpApi account and API key. | 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 | 250 searches a month on the free plan; only successful searches count. | A free trial with no credit card needed; the trial length is not stated. |
| Paid | Starter plan at $25 a month for 1,000 searches. | Not stated on its pages |
| Acting on a result | Ticket links: each result lists ticket sources with links (to the sellers Google shows). | Nothing: the event schema has no ticket or booking link. |
| Limits on keeping or showing results | SerpApi keeps search data for 31 days on its side; its terms have no limit on how long you keep 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 | 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 | Wherever Google shows events; set location at city level. | Global. |
| MCP server | Official SerpApi MCP server (all engines, one search tool) at https://mcp.serpapi.com/YOUR_SERPAPI_API_KEY/mcp. | Official hosted MCP server at https://mcp.predicthq.com/v1/mcp (OAuth or API key). |
