Google Javascript API Geocoding Limits

Question

What are the limits for client side geocoding with Google Maps JavaScript API v3?

My research:

1. Google Maps PHP API has a limit of 2500 geocode reques

Answer 1

Always read the latest you can find on an official Google website for the proper API version, a dated stackoverflow answer is not an up-to-date reference !!!

Here is what it said when I wrote this answer:

Google Maps Geocoding API Usage Limits

2,500 free requests per day, calculated as the sum of client-side and server-side queries.

50 requests per second, calculated as the sum of client-side and server-side queries.

Enable pay-as-you-go billing to unlock higher quotas:

$0.50 USD / 1000 additional requests, up to 100,000 daily.

In general I think Google is happy as long as the queries come from real human users as this is of some value to them.

There are also ways to save a few requests by caching results for up to 30 days: https://developers.google.com/maps/premium/optimize-web-services#optimize
