Authentication & Authorization

The bloqr-backend uses Better Auth as its sole authentication provider. Better Auth runs entirely within the Cloudflare Worker, backed by Neon PostgreSQL via Cloudflare Hyperdrive and the Prisma ORM. No third-party auth service is required at runtime.

Authentication Methods

The system supports three authentication methods:

Better Auth session — Cookie or bearer session token. Created on sign-up/sign-in. Supports email+password and GitHub OAuth. Active when a valid session exists in the database.
API key — Long-lived programmatic access key (blq_ prefix). Created via the API keys dashboard. Verified by hashing and database lookup on every request.
Anonymous — No credentials. Lowest rate limits. Access to public endpoints only.

Tier System

Tier	Rate Limit	Description
`anonymous`	10 req/min	Unauthenticated — public endpoints only
`free`	60 req/min	Registered user — standard access
`pro`	300 req/min	Paid subscriber — higher limits
`admin`	Unlimited	Administrator — full system access

Tiers are resolved from the database user.tier field on every request. They are never trusted from JWT claims (Zero Trust principle).
