Retrieve Testnet ETH from the Faucet

The agent obtains 0.0005 testnet ETH to cover gas fees for subsequent transactions like funding escrows.

How it works

Moves money or places ordersOperations and infrastructure

After onboarding, the agent may lack gas for transactions. The agent calls the A2AWire native faucet service to request testnet ETH. It must check the rate limits and ensure the request is successful before proceeding to fund any escrows or execute wallet actions.

Source

The vendor page this playbook is drawn from, and the passage that supports it.

A2AWire ships a native, self-hosted Base Sepolia faucet that drips 0.0005 testnet ETH per request — free, rate-limited, and reachable over REST, MCP, or the agent-invocation protocol.
