Google Maps API自定义项目是否沿用官网10个目的地限制的技术问询

Great question! Let’s break this down clearly—the 10-destination limit you see in the Google Maps web browser app doesn’t apply to the Google Maps APIs for developer projects. Here’s what you need to know:

Key Differences Between Web App and API Limits #

The 10-stop cap is a restriction for the consumer-facing Google Maps web tool, designed for casual everyday use. Developer APIs have much more flexible limits tailored to project needs, though specifics depend on which API you use:

1. Directions API #

The classic Directions API (used for basic route planning) allows up to 25 total locations per request—that’s your starting point, plus 23 waypoints, plus your final destination. This is way more than the web app’s 10-stop limit.

A quick note: While the API supports this, keep in mind that each waypoint adds to the request complexity, which can affect both response time and billing. Make sure to review the pricing details for multi-waypoint requests.

2. Routes API (Next-Gen) #

If you need to handle large numbers of destinations (think dozens or even hundreds) and want optimized routing (like finding the most efficient order to visit stops), the Routes API is the way to go. Its computeRoutes endpoint supports advanced multi-stop planning, including vehicle routing problem (VRP) solutions for complex scenarios.

This is perfect for use cases like delivery routes, field service scheduling, or your academic project if you need to process more than 25 stops.

Important Reminders #

• Permissions & Quotas: Ensure your API key has the appropriate APIs enabled (either Directions API or Routes API) in the Google Cloud Console. Default quotas should cover most academic project needs, but you can adjust them if required.
• Billing: Even though academic projects might qualify for free credits, always check the pricing for multi-waypoint or large-scale routing requests to avoid unexpected costs.
• Route Optimization: The Directions API follows the exact order of waypoints you provide. If you need to optimize the stop order for efficiency, use the Routes API’s optimization features instead.
