Foursquare Places API vs SerpApi Google Maps API for AI agents
Foursquare Places API is Foursquare's pay-as-you-go API for searching and reading point-of-interest data from its global places database. SerpApi Google Maps API is a third-party API that scrapes Google Maps search results and returns them as structured JSON.
The short answer
- Foursquare Places API: A low-cost global POI API with phone, website and email at the cheaper Pro tier. Good for place lookup and matching where Google-style display rules are too tight.
- SerpApi Google Maps API: Getting Google Maps listing data (phone, website, hours, ratings) as JSON without Google's billing or display rules. Legal risk from the scraping model sits partly with you.
