Build secure APIs in minutes
How it works
From endpoint to production in three steps
Deploy authenticated, rate-limited APIs with auto-generated documentation—no boilerplate required.
- 1
Step 1
Define your endpoints
Write your API routes using standard REST conventions. Our platform automatically validates request schemas and generates type-safe handlers.
- 2
Step 2
Configure authentication
Choose from API keys, OAuth 2.0, or JWT tokens. Set permissions per endpoint with role-based access control that updates in real-time.
- 3
Step 3
Deploy and monitor
Push to production with zero-downtime deployments. Track usage, latency, and errors in a unified dashboard with automatic OpenAPI spec generation.

Rate limits that adapt to your traffic
Set global and per-endpoint quotas with sliding windows, token buckets, or custom algorithms. Limits update instantly across all edge nodes, and clients receive precise retry-after headers. Burst allowances let legitimate spikes through while blocking abuse—no manual intervention required.

Under the hood
The edge architecture that keeps latency low
Edge-first authentication
API keys and JWT tokens validate at the CDN edge, before your origin sees traffic. A global cache keeps hot keys in memory, so p99 auth overhead stays under 5 ms even at 100k req/s.
Distributed rate limiting
Counters sync across regions every 100 ms using CRDTs. A client hammering Tokyo and London simultaneously hits one combined quota, and the limit updates faster than a single datacenter round-trip.
Zero-config OpenAPI generation
The platform infers request and response schemas from your route handlers and type annotations. Every deploy updates the live spec, and the docs UI reflects changes in under a second.
Automatic retry and backoff
Rate-limit responses include precise retry-after timestamps and a client SDK that exponentially backs off. Overloaded endpoints shed load gracefully without cascading failures or manual circuit breakers.
