Mapbox Search Box API vs SerpApi Google Maps API for AI agents

Mapbox Search Box API is Mapbox's search API for addresses, places and POIs, with interactive (/suggest + /retrieve), text (/forward), category and reverse endpoints. SerpApi Google Maps API is a third-party API that scrapes Google Maps search results and returns them as structured JSON.

The short answer

  • Mapbox Search Box API: Cheap autocomplete-style place and address search inside map apps, with a first-party hosted MCP server.
  • 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.
