sardis-crewai 1.1.0

CrewAI integration for Sardis - agent payment tools, pre-built agents, and task templates

sardis-crewai

CrewAI integration for Sardis -- the Payment OS for the Agent Economy.

Build multi-agent financial workflows where AI agents can make real payments, enforce spending policies, and maintain audit trails through the Sardis platform.

Installation

pip install sardis-crewai

Quick Start

Using Individual Tools

from sardis import SardisClient
from sardis_crewai import SardisPayTool, SardisCheckBalanceTool

client = SardisClient(api_key="sk_test_...")
wallet = client.wallets.create(name="my-agent", chain="base", policy="Max $100/day")

# Create tools
pay = SardisPayTool(client=client, wallet_id=wallet.wallet_id)
balance = SardisCheckBalanceTool(client=client, wallet_id=wallet.wallet_id)

# Use with any CrewAI agent
from crewai import Agent

agent = Agent(
    role="Buyer",
    goal="Purchase API credits",
    backstory="You buy software for the team.",
    tools=[pay, balance],
)

Using Pre-configured Agents

from sardis import SardisClient
from sardis_crewai import create_finance_agent, create_audit_agent
from sardis_crewai import create_payment_task, create_audit_task
from crewai import Crew

client = SardisClient(api_key="sk_test_...")
wallet = client.wallets.create(name="finance-bot", chain="base")

# Create agents with sensible defaults
finance = create_finance_agent(client=client, wallet_id=wallet.wallet_id)
auditor = create_audit_agent(client=client, wallet_id=wallet.wallet_id)

# Create tasks
pay_task = create_payment_task(
    agent=finance,
    recipient="openai.com",
    amount="25.00",
    purpose="Monthly API credits",
)
audit_task = create_audit_task(agent=auditor)

# Run the crew
crew = Crew(agents=[finance, auditor], tasks=[pay_task, audit_task])
result = crew.kickoff()

Multi-Agent Team with Group Budgets

from sardis import SardisClient
from sardis_crewai import (
    create_procurement_agent,
    create_audit_agent,
    create_bulk_payment_task,
    create_budget_review_task,
)
from crewai import Crew

client = SardisClient(api_key="sk_test_...")

# Create a shared group budget
group = client.groups.create(
    name="engineering",
    budget={"per_transaction": "200", "daily": "1000", "monthly": "30000"},
)

# Create wallets attached to the group
buyer_wallet = client.wallets.create(
    name="buyer", chain="base", group_id=group.group_id,
)
auditor_wallet = client.wallets.create(
    name="auditor", chain="base", group_id=group.group_id,
)

# Create agents
buyer = create_procurement_agent(
    client=client, wallet_id=buyer_wallet.wallet_id, group_id=group.group_id,
)
auditor = create_audit_agent(
    client=client, wallet_id=auditor_wallet.wallet_id, group_id=group.group_id,
)

# Define tasks
purchase_task = create_bulk_payment_task(
    agent=buyer,
    payments=[
        {"to": "openai.com", "amount": "30.00", "purpose": "API credits"},
        {"to": "anthropic.com", "amount": "25.00", "purpose": "API credits"},
        {"to": "github.com", "amount": "19.00", "purpose": "Copilot subscription"},
    ],
)
review_task = create_budget_review_task(agent=auditor, group_id=group.group_id)

crew = Crew(agents=[buyer, auditor], tasks=[purchase_task, review_task])
result = crew.kickoff()

Available Tools

Tool	Description
SardisPayTool	Execute payments with policy enforcement and audit logging
SardisCheckBalanceTool	Check wallet balance, limits, and remaining budget
SardisCheckPolicyTool	Validate payments against policy without executing
SardisSetPolicyTool	Set spending policy from natural language description
SardisGroupBudgetTool	Check shared group budget status across agents

Tool Factory

Use create_sardis_tools() to generate a tool set in one call:

from sardis_crewai import create_sardis_tools

# All tools (read + write)
tools = create_sardis_tools(client, wallet_id=wallet.wallet_id)

# Read-only tools (for audit agents)
tools = create_sardis_tools(client, wallet_id=wallet.wallet_id, read_only=True)

# With group budget monitoring
tools = create_sardis_tools(client, wallet_id=wallet.wallet_id, group_id="group_abc")

Pre-configured Agents

Agent Factory	Role	Capabilities
create_finance_agent()	Finance Manager	Full payment + policy + audit
create_procurement_agent()	Procurement Specialist	Vendor payments + budget checks
create_audit_agent()	Financial Auditor	Read-only balance + policy checks

All agent factories accept **agent_kwargs to override any crewai.Agent parameter.

Task Templates

Task Factory	Purpose
create_payment_task()	Single payment with pre-checks
create_bulk_payment_task()	Batch payment execution
create_budget_review_task()	Group budget status report
create_audit_task()	Compliance audit of recent transactions
create_policy_setup_task()	Configure policy from natural language

Simulation Mode

By default, Sardis runs in simulation mode -- all payments execute locally without real blockchain transactions. This is ideal for developing and testing CrewAI workflows:

# No API key needed for simulation
client = SardisClient()
wallet = client.wallets.create(name="test-agent", chain="base", initial_balance=1000)

To use production mode, provide a real API key and install sardis-sdk:

pip install sardis-sdk

client = SardisClient(api_key="sk_live_...")
