Authentication: OAuth 2.0 (user data) or API keys (public data). Service accounts for server-to-server.

Client libraries in most languages (Python, JS, Java, Go, etc.) — generated from discovery documents.

API Explorer: browser-based tool to test any Google API call without code.

Billing: some APIs are free (Calendar, basic Gmail), others are pay-per-use (Maps, Cloud AI, BigQuery).

Rate limits vary wildly per API. Exponential backoff is standard practice.
