API Idempotency Basics
Make repeat calls safe
Designing idempotent APIs means using idempotency keys, PUT/DELETE semantics where appropriate, and guards against duplicate processing so retries don't create extra charges or actions.

Use Keys
Accept idempotency keys for unsafe operations like payments.
Choose Methods
Use PUT/DELETE when possible; ensure handlers are safe on retry.
Prevent Dupes
Store request hashes/status; handle 202/303 patterns gracefully.

API Basics
APIs let software request data or actions from other systems through defined endpoints and responses.
Comparison
RAM vs Storage
RAM handles what your device is actively working on, while storage keeps apps, files, and system data available over time.
How it works
Global Positioning System
GPS uses timing signals from satellites to calculate a receiver's position on Earth.
What it is
Blockchain
A blockchain is a distributed ledger secured by cryptography and consensus nodes.
