`class Client`

Faraday-based A2A protocol client.

Supports both protocol bindings: JSON-RPC 2.0 and HTTP+JSON/REST. Uses the async-http-faraday adapter for fiber-based non-blocking I/O and supports SSE streaming for long-lived connections.

Request params are validated against the operation's request schema before sending. Responses are returned as Schema::Definition objects.

JSON-RPC (default)

client = A2A::Client.new("http://localhost:9292")

REST

client = A2A::Client.new("http://localhost:9292", binding: :rest)

  A2A::Schema["Agent Card"].new(parsed)
