Everything you need

to backups. Your app stays online.

Rate Limiting

Control costs and prevent abuse with limits per user,
IP, or project.

Real-time

Show responses as they generate for a snappy,
real-time experience.

Webhooks

Get notified when requests complete. Perfect for
background processing.

Event-Driven Workflows

AI generates, you process, then respond. Perfect for
tool calling and complex multi-step workflows.

Structured Output

Get consistent JSON responses that match your schema.
No more parsing surprises.

Analytics

See what's working and what's not. Track usage,
latency, and errors in one console.

Debugging

and full request/response inspection.
