Interface A2AHttpClient

All Known Implementing Classes:
AndroidA2AHttpClient, JdkA2AHttpClient, VertxA2AHttpClient
public interface A2AHttpClient
HTTP client interface for making HTTP requests to A2A agents.

Provides a fluent builder API for constructing and executing HTTP requests with support for GET, POST, and DELETE methods. Includes support for both synchronous requests and asynchronous Server-Sent Events (SSE) streaming.

Usage Example

A2AHttpClient client = A2AHttpClientFactory.create();

// Synchronous GET request
A2AHttpResponse response = client.createGet()
    .url("http://localhost:9999/api/endpoint")
    .addHeader("Authorization", "Bearer token")
    .get();

// Synchronous POST request
A2AHttpResponse response = client.createPost()
    .url("http://localhost:9999/message:send")
    .body("{\"message\": \"Hello\"}")
    .post();

// Asynchronous SSE streaming
CompletableFuture<Void> future = client.createPost()
    .url("http://localhost:9999/message:stream")
    .body(jsonBody)
    .postAsyncSSE(
        event -> System.out.println("Event: " + event.data()),
        error -> System.err.println("Error: " + error),
        () -> System.out.println("Stream complete")
    );
