@ucanto/interface

@ucanto/interface provides shared type definitions and contracts used across the ucanto ecosystem. It ensures consistent and type-safe interactions between different modules, facilitating seamless integration.

What It Provides

• Shared Type Definitions: Standardized types for capabilities, invocations, and responses.
• Interface Contracts: Defines clear API contracts for ucanto modules.
• Type Safety: Enhances reliability through TypeScript-based type checking.

How It Fits with Other Modules

• @ucanto/core: Uses the interfaces to define and execute capabilities.
• @ucanto/server: Implements service logic based on interface definitions.
• @ucanto/transport: Adopts standardized encoding and transport interfaces.
• @ucanto/principal: Uses identity-related interfaces for cryptographic operations.
• @ucanto/client: Ensures consistent request and response structures.

For an overview and detailed usage information, refer to the main ucanto README.
