CrewAI Integration

Add Lightning payment capability to any CrewAI crew. Agents can access L402-protected APIs with automatic micropayments.

Install​

pip install l402-requests[crewai]

Set your wallet:

export STRIKE_API_KEY="your-strike-api-key"

Quick Start​

from crewai import Agent, Crew, Task
from l402_requests import L402Client, BudgetController
from l402_requests.integrations.crewai import L402GetTool, L402PostTool, L402SpendingTool

# Shared client for the whole crew
client = L402Client(
    budget=BudgetController(max_sats_per_request=500, max_sats_per_hour=5000),
)

# Tools
get_tool = L402GetTool(client=client)
post_tool = L402PostTool(client=client)
spending_tool = L402SpendingTool(client=client)

# Agent
researcher = Agent(
    role="API Researcher",
    goal="Fetch data from L402-gated APIs and summarize findings.",
    backstory="Expert at accessing Lightning-gated APIs.",
    tools=[get_tool, spending_tool],
)

# Task
task = Task(
    description="Get SEC filing data for Tesla from agent-commerce.store/api/edgar/company/TSLA",
    expected_output="Summary of Tesla's recent SEC filings.",
    agent=researcher,
)

# Run
crew = Crew(agents=[researcher], tasks=[task])
result = crew.kickoff()
