It provides a framework for agents to communicate asynchronously over multiple transports\u2014JSON-RPC, HTTP+JSON/REST, and gRPC\u2014with built-in support for modern async Python. The core library is lightweight, but the SDK includes optional integrations for HTTP servers (FastAPI, Starlette), distributed tracing (OpenTelemetry), and SQL persistence (PostgreSQL, MySQL, SQLite), allowing you to compose a deployment stack suited to your needs.\n\nThe SDK is maintained actively and supports Python 3.10 through 3.14. It implements the A2A Protocol specification version 1.0 with backward compatibility for 0.3, so agents built with this SDK can interoperate with other A2A-compliant implementations. The 8 core runtime dependencies are all established ecosystem packages, and the install is low-friction.","worth_installing":"Yes. The SDK is actively maintained, has no known vulnerabilities, uses a permissive Apache 2.0 license, and requires only standard ecosystem dependencies. It is well-suited for anyone building agent-to-agent communication systems that need to follow a standardized protocol. The optional extras allow you to scale from simple local agents to distributed, observable, persistent deployments. Start with the core install and add extras as your use case demands."},"id":"a2a-sdk","links":{"html":"https://skillfed.io/packages/a2a-sdk","md":"https://skillfed.io/packages/a2a-sdk.md","pypi":"https://pypi.org/project/a2a-sdk/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-22","license_spdx":"Apache-2.0","license_treatment":"permissive","name":"a2a-sdk","python_support":"supports_current","summary":"A2A Python SDK"},"popularity":{"monthly_downloads":12367877,"position":1323,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.1.2"}
