Design API Architectures with AI-Powered Diagrams

Whether you're building REST APIs, GraphQL gateways, or gRPC services, visualize your API architecture by describing it in natural language.

The challenge

APIs are the backbone of modern applications, but their architecture can be surprisingly complex. Authentication flows, rate limiting, request routing, database queries, caching strategies, webhook delivery, and third-party integrations all need to be understood by your team. A well-structured API architecture diagram communicates all of this at a glance.

The solution

Describe your API architecture naturally:

"Mobile and web clients send requests to a GraphQL gateway (Apollo). The gateway authenticates via OAuth 2.0, checks rate limits in Redis, and resolves queries by calling three REST microservices: Users API, Products API, and Orders API. Each API has its own PostgreSQL database. The Orders API also publishes events to an SQS queue that triggers a Lambda function for webhook delivery to merchant endpoints. All API responses are cached in CloudFront."

The AI generates a clear diagram showing every API layer, authentication flow, and data path. Iterate with chat to add versioning, error handling paths, or monitoring.

API patterns we support

REST API with gateway
API Gateway handling routing, authentication, rate limiting, and request transformation for multiple backend services.

gRPC service mesh
High-performance inter-service communication with protobuf schemas, load balancing, and service discovery.
Webhook delivery system
Event-driven webhook infrastructure with queuing, retry logic, delivery tracking, and dead letter handling.
