The Routes API is one of the APIs that Google Maps Platform publishes on the APIs.io network. Its job is narrow and load-bearing: compute routes and route matrices with real-time traffic. It is tagged Directions, Routing, Tolls, and Traffic, which is a tidy summary of everything that makes turn-by-turn navigation harder than drawing a line between two points.
What the catalog exposes
Routes API is one of 38 APIs Google Maps Platform ships on the network. The published artifact set here is documentation-first, exactly what you want when the API itself is a black box you call over HTTPS. The properties on the entry point to five resources:
- Documentation, the overview of what Routes does
- an API Reference for the REST surface
- a Getting Started guide walking through computing route directions
- Release Notes to track what has changed
- a Support channel
That set covers the full arc of adoption. You can understand the service, wire up your first call, and keep watching it evolve without leaving the linked docs.
One sharp observation
The description says the quiet part directly: Routes API replaces the Directions and Distance Matrix APIs. That is the whole point. Google collapsed two long-standing products into one surface that computes both single routes and route matrices, and it did so with real-time traffic baked in rather than bolted on. Traffic-aware routing is not a flag you flip on a static graph, it is a continuously updated model of the road network, and that is why the older APIs are being retired rather than extended. If you are still calling Directions or Distance Matrix, the Routes API is where that functionality is consolidating, and the tags on this entry, Tolls included, hint that the newer surface also carries cost and constraint data the old endpoints never modeled cleanly.
For anyone building logistics, dispatch, ETA, or delivery-window features, this is the primitive underneath. A route matrix answering “how long from each of these origins to each of these destinations, right now, in traffic” is the query that powers assignment and sequencing at scale.
Takeaway
The Routes API is the modern, traffic-aware core of Google Maps routing, and it is actively absorbing the Directions and Distance Matrix products. Read the official documentation for the request shape, then browse the rest of the Google Maps Platform provider profile on APIs.io to see the geocoding, places, and navigation APIs that sit alongside it. Routing rarely travels alone.
