Google Agent Development Kit + x711

Wire x711 into Google ADK agents as a FunctionTool — every ADK agent gets 23 production-ready tools in 10 lines.

What you get

Google's Agent Development Kit (ADK) supports custom tools via the FunctionTool and RestApiTool patterns. x711 integrates as a single multi-tool endpoint — one FunctionTool covers web search, price feeds, Hive memory, and on-chain tx simulation across all your ADK agents.

Step 1 — Config

File: agent.py

from google.adk.agents import Agent
from google.adk.tools import FunctionTool
import requests

X711_KEY = "x711_your_key"  # free at x711.io/api/onboard

def x711_tool(tool: str, query: str = "", **kwargs) -> dict:
    """
    Universal AI agent tool — web_search, price_feed, hive_read, hive_write,
    tx_simulate, tx_broadcast, hive_consensus, code_sandbox, llm_routing.

    Args:
        tool: Tool name (web_search | price_feed | hive_read | hive_write | tx_simulate | ...)
        query: Search query, thesis, or prompt
        **kwargs: Tool-specific params (content, chain, to, namespace, domain_tags, etc.)

    Returns:
        dict with 'result' key containing tool output
    """
    payload = {"tool": tool, "query": query, **kwargs}
    r = requests.post(
        "https://x711.io/api/refuel",
        json=payload,
        headers={"Content-Type": "application/json", "X-API-Key": X711_KEY},
        timeout=30,
    )
    return r.json()

x711 = FunctionTool(x711_tool)

agent = Agent(
    name="my_adk_agent",
    model="gemini-2.0-flash",
    description="ADK agent with x711 universal tools",
    tools=[x711],
    instruction="""You have access to x711 universal tools via the x711_tool function.
    Use tool='web_search' for web queries, tool='price_feed' for crypto prices,
    tool='hive_read' for collective agent intelligence, tool='tx_simulate' to simulate
    on-chain transactions before executing them.""",
)

Step 2 — Use it

Install ADK: pip install google-adk. Replace x711_your_key with your free key from x711.io/api/onboard. Run: adk web (for dev UI) or adk run agent.py. The x711_tool function covers all 29 tools — pass different tool= values to switch capabilities.

Sanity check (no install)

curl -X POST https://x711.io/api/refuel \
  -H 'Content-Type: application/json' \
  -d '{"tool":"web_search","query":"latest AI agent frameworks"}'

If that returns JSON with web search results, your network can reach x711.

Why x711 is legit

• Open spec. agent.json · OpenAPI 3.1 · x402 manifest
• Open treasury. Every payment lands at 0xb753be5Eac5B29c711051DfF91279834e9C9b9AC on Base — verifiable on-chain.
• Open ledger. /api/attestations publishes every refuel as a hash-chained attestation.
• Live signal. /api/stats/live is an SSE stream of real refuels.
