x711 + CrewAI: give your crew real-time tools without managing API keys

CrewAI agents need tools. The standard answer is to wire up 5 different API keys for search, prices, data, and execution. x711 replaces all of them with one endpoint and one key.

Get your key 

curl -X POST https://x711.io/api/onboard \
  -d '{"name":"my-crewai-fleet"}'
# → {"api_key":"x711_..."}

Define the tools 

import requests
from crewai.tools import BaseTool

X711_KEY = "x711_your_key_here"

class X711Tool(BaseTool):
    tool_name: str
    name: str
    description: str

    def _run(self, **kwargs) -> str:
        r = requests.post(
            "https://x711.io/api/refuel",
            headers={"X-API-Key": X711_KEY},
            json={"tool": self.tool_name, **kwargs},
            timeout=15,
        )
        return str(r.json())

web_search = X711Tool(
    tool_name="web_search",
    name="WebSearch",
    description="Search the live web. Input: query (str)",
)
price_feed = X711Tool(
    tool_name="price_feed",
    name="PriceFeed",
    description="Live crypto/stock prices. Input: assets (list[str])",
)
tx_simulate = X711Tool(
    tool_name="tx_simulate",
    name="TxSimulate",
    description="Dry-run a transaction before sending. Inputs: chain, from, to, data",
)
hive_read = X711Tool(
    tool_name="hive_read",
    name="HiveRead",
    description="Read collective agent memory. Input: namespace, query",
)

Wire into your crew 

from crewai import Agent, Task, Crew

researcher = Agent(
    role="Market Researcher",
    goal="Find actionable DeFi opportunities using live data",
    backstory="You are a DeFi analyst with access to real-time prices and web search.",
    tools=[web_search, price_feed, hive_read],
    verbose=True,
)

analyst = Agent(
    role="On-chain Analyst",
    goal="Validate opportunities by simulating transactions before execution",
    backstory="You verify every opportunity with a dry-run simulation.",
    tools=[tx_simulate],
    verbose=True,
)

research_task = Task(
    description="Find the top 3 yield opportunities on Base chain right now.",
    agent=researcher,
    expected_output="3 opportunities with APY, TVL, and risk level",
)

validate_task = Task(
    description="For each opportunity, simulate a $1000 USDC deposit transaction.",
    agent=analyst,
    expected_output="Simulation results showing gas cost and success probability",
)

crew = Crew(agents=[researcher, analyst], tasks=[research_task, validate_task])
result = crew.kickoff()
