The exported symbols, their type definitions, and the options each one takes. For how the pieces fit together, start with the guide.

Methods

Method	What it does
createClient	Creates a client from default fetch options. Every APIful client starts here.
createOpenAPIClient	Creates a client typed from a generated OpenAPI schema, without the extension chain.
defineApifulConfig	Declares the services the generate command reads.

Types

Type	What it describes
ApiClient	The client itself: its default options and the with method that extends it.
HandlerExtensionBuilder	An extension that gives the client its call signature.

Extensions

OpenAPI Type Helpers reach into a generated schema for the request and response types of a single operation – useful when you need to name one in a signature of your own.
