Create API keys scoped to specific services or environments. Supports both test and production modes.

Security

Keys are hashed at rest with AES-256. IP allowlisting, domain restrictions, and automatic expiry available.

Rate Limits

Tiered rate limiting based on plan. Free tier: 100 req/min. Pro: 1,000 req/min. Enterprise: custom.
