Place ID Finder

In the Place ID Finder sample, you search for a place by its address, and then the sample adds a marker for the place to the map and displays its place ID in an info window.

To learn how to use place IDs, see Place IDs.

To look up place IDs from code or an AI agent instead of with this interactive sample, use one of the following APIs. For details, see Find place IDs from code or an AI agent.

From your code: Call Place.searchByText and request only the id field.
From an AI agent or LLM app: Use the Resolution API in Maps Experience agent tools, available as the resolve_names and resolve_maps_urls MCP tools.

Clone Sample

Git and Node.js are required to run this sample locally. Follow these instructions to install Node.js and NPM. You will also need a Google Maps API key.

The following commands clone the repository, install dependencies, and copy the environment file.

  git clone https://github.com/googlemaps-samples/js-api-samples.git
  cd js-api-samples
  npm i
  cp .env.template .env

Once you copy the environment file, make sure to open the .env file and replace <Insert your own development API key here> with your actual API key before starting the sample.

  cd samples/places-placeid-finder
  npm start
