# Backblaze

> Backblaze is a cloud storage and data-backup provider. Its B2 Cloud Storage is a low-cost, S3-compatible object-storage service exposed through two APIs: the B2 Native API (JSON over HTTPS, token auth via b2_authorize_account) and an S3-Compatible API (AWS Signature V4). This file is generated by API Evangelist from the apis.io catalog entry for Backblaze; it links the human docs and the machine-readable API artifacts we maintain.

## APIs
