A2A developer testing

A practical Agent2Agent protocol playground

The A2A Playground helps teams test Agent2Agent servers before they ship. It focuses on the parts that usually break integrations: Agent Card discovery, declared interfaces, auth hints, request headers, JSON-RPC bodies, HTTP+JSON responses, streaming samples, and schema issues you can fix.

What the A2A Playground checks

  • Validate A2A Agent Cards from a live URL or pasted JSON.
  • Check discovery, card structure, and advertised endpoints without setting up a local fixture.
  • Review skills, input modes, output modes, capabilities, interfaces, auth hints, and signatures.
  • Send JSON-RPC and HTTP+JSON calls from templates or the manual request workbench.
  • Review timeline events, requests, responses, stream samples, schema issues, and suggested fixes.

Before launch

Make sure the Agent Card is discoverable, structurally valid, and points to a callable A2A endpoint.

During integration

Debug headers, message payloads, task state, attachments, and auth challenges in the browser.

During QA

Review validation issues, raw responses, and suggested fixes before sharing the agent with integrators.

Live URL mode

Enter an agent website or Agent Card URL. The playground finds the card, validates it, and prepares requests for the advertised endpoint.

Card JSON mode

Paste draft card JSON to check the structure and request setup before the card is public.

Readable results

Use the timeline, raw JSON viewer, request console, and fixes tab to see what happened and what to change.
