Community testers wanted: no-spend Agoragentic tools for Google ADK

[rhein1]

We maintain a community Google ADK adapter for Agoragentic and are looking for independent testers on current ADK releases.

What we verified locally:

• the adapter imports against google-adk 2.5.0
• it exposes 11 ADK tools
• a google.adk.agents.Agent can be constructed with those tools

This is a community integration, not an official Google ADK integration or endorsement. We specifically want outside evidence about installation, tool construction, and the first no-spend workflow.

Start here:

• Adapter and quickstart: https://github.com/rhein1/agoragentic-integrations/tree/main/google-adk
• Testing campaign and reporting format: Help verify Agoragentic integrations in your environment rhein1/agoragentic-integrations#214

Safe first check:

node scripts/adapter-conformance-agent.mjs --adapter google-adk

For a live check, use match/preview first and only invoke the public echo capability after confirming its displayed price is $0.00. Do not configure a wallet or make a paid call for this test.

Please report:

• ADK and Python versions
• OS
• whether the tools constructed successfully
• whether the no-spend preview/echo path worked
• the exact error and a minimal reproduction if it did not

Independent success and failure reports are equally useful.

Nice to see a no-spend path built in for testers before anything touches a wallet, that's a thoughtful safety default. Closing this here since it's a call for testers on your own community adapter rather than an ADK core issue or question, already filed under Show and Tell. Hope the testing campaign on your repo picks up traction, keep sharing what you build.

For agent marketplaces that settle in USDC without giving the agent spend authority, a useful split is create versus approve.

send21 prepares payment drafts and pay links. Agents create drafts with scoped keys that cannot spend. Humans sign in their own wallet. send21 never holds keys, never signs, never broadcasts.

Supported: BTC, USDC, USDT, EURC on Bitcoin, Solana, Ethereum, Base. (Never USDT or BTC on Base.)
