What is the difference between Google API Services and Google Cloud Platform?

Google API Services and Google Cloud Platform are related but distinct: Google APIs are individual product endpoints, such as the Maps Platform, the YouTube Data API, or Cloud Vision, that any application can call, while Google Cloud Platform (GCP) is Google's full cloud computing platform for hosting and running infrastructure. Calling a Google API is one narrow way to use a slice of Google's services; it is not the same as building or hosting an application on Google's cloud.

Where does the confusion come from?

The two get lumped together because they share the same front door. Both individual API usage and GCP infrastructure are set up and billed through the same Google Cloud Console, and both rely on the same IAM and OAuth 2.0 credential system to authenticate requests. A developer who has only ever generated an API key for the Maps Platform inside that console can walk away thinking they have used GCP, when in reality they have touched a small corner of it. The reverse happens too: teams running full infrastructure on GCP sometimes describe that work loosely as "using Google APIs," even though most of what they are doing is provisioning servers and databases, not calling product endpoints.

How different is the actual scope?

GCP is a platform of infrastructure and data services: Compute Engine for virtual machines, Cloud Storage for object storage, BigQuery as a data warehouse, Google Kubernetes Engine and Cloud Run for container workloads, and Vertex AI for building and training machine learning models. Google APIs, by contrast, are discrete product endpoints, Maps, YouTube Data, Cloud Vision, Cloud Translation, the Workspace APIs, that an application calls over HTTP regardless of where that application itself runs. A Maps API request behaves the same whether the backend making it is hosted on GCP, on AWS, or on a company's own server. That portability is the clearest sign the two are not the same thing: one is infrastructure you build on, the other is a service you call into.

What does this mean for hiring or scoping a project?

The practical consequence shows up when scoping work. Someone who can wire a Maps or YouTube API integration into an existing app is doing integration work, a narrower and generally faster task. Someone who can architect infrastructure on Compute Engine, GKE, or BigQuery is doing cloud infrastructure work, a different skill set involving networking, scaling, and cost management. Listing "Google API experience" on a job requirement does not guarantee GCP infrastructure experience, and the reverse is equally true. Projects that need both should specify that clearly rather than assuming one implies the other.
