a2a.utils.json_utils module

JSON serialization helpers for the A2A Python SDK.

a2a.utils.json_utils.dumps(obj: Any) → str

Serialize obj to a JSON-formatted str with UTF-8 defaults.

Use this in SSE/streaming code paths where payloads are serialized manually before being written to the wire. Unary HTTP responses do not need it because Starlette’s JSONResponse.render already calls json.dumps(content, ensure_ascii=False, ...) internally; this helper makes the streaming paths behave identically so non-ASCII characters (CJK, emoji, etc.) reach clients as raw UTF-8 rather than escape sequences.
