CrewAI tools for BoltzPay — pay for API data with AI agents

boltzpay-crewai

CrewAI tools for BoltzPay — two integration paths for paid API access with AI agents.

Recommended: MCP Integration

CrewAI natively supports MCP. Our MCP server works out of the box — no Python package needed.

See the complete guide: MCP Integration Guide

from crewai import Agent, Task, Crew
from crewai_tools import MCPServerAdapter
from mcp import StdioServerParameters

server_params = StdioServerParameters(
    command="npx",
    args=["-y", "@boltzpay/mcp"],
    env={"BOLTZPAY_DAILY_BUDGET": "5.00"},
)

with MCPServerAdapter(server_params) as tools:
    agent = Agent(role="Researcher", goal="Access paid APIs", tools=tools)
    task = Task(description="Discover paid APIs", expected_output="API list", agent=agent)
    Crew(agents=[agent], tasks=[task]).kickoff()

Alternative: CLI Bridge Tools

For users who prefer native Python tools, this package provides 7 BaseTool subclasses that call @boltzpay/cli via subprocess.

Install

pip install boltzpay-crewai

Prerequisites

• Python 3.10+
• Node.js 20+ — required for the CLI bridge (nodejs.org)
• Coinbase CDP keys (optional) — only needed for fetch

Usage

from crewai import Agent, Task, Crew
from boltzpay_crewai import (
    BoltzPayFetchTool,
    BoltzPayCheckTool,
    BoltzPayDiscoverTool,
)

agent = Agent(
    role="Data Researcher",
    goal="Find and access paid APIs using BoltzPay",
    tools=[BoltzPayFetchTool(), BoltzPayCheckTool(), BoltzPayDiscoverTool()],
)

task = Task(
    description="Discover paid APIs and check pricing for invy.bot",
    expected_output="API pricing report",
    agent=agent,
)

crew = Crew(agents=[agent], tasks=[task])
result = crew.kickoff()

Tool Reference

Tool	Name	Description	Credentials
BoltzPayFetchTool	boltzpay_fetch	Fetch data from a paid API. Detects x402/L402, pays with USDC or Lightning.	Required
BoltzPayCheckTool	boltzpay_check	Check if URL requires payment. Returns protocol and pricing.	Not needed
BoltzPayQuoteTool	boltzpay_quote	Get detailed price quote with chain options.	Not needed
BoltzPayDiscoverTool	boltzpay_discover	Browse directory of compatible paid APIs.	Not needed
BoltzPayBudgetTool	boltzpay_budget	Check daily spending budget and remaining balance.	Not needed
BoltzPayHistoryTool	boltzpay_history	View recent payment transactions.	Not needed
BoltzPayWalletTool	boltzpay_wallet	Check wallet address and USDC balance.	Not needed

No Credentials Needed

Six tools work without any Coinbase credentials:

from boltzpay_crewai import BoltzPayCheckTool, BoltzPayDiscoverTool

# Discover APIs and check prices — no keys required
agent = Agent(
    role="API Scout",
    goal="Evaluate paid APIs without purchasing",
    tools=[BoltzPayCheckTool(), BoltzPayDiscoverTool()],
)

Error Handling

CLI bridge tools return error strings instead of raising exceptions (CrewAI pattern), so your agent can recover gracefully:

Error (NODE_NOT_FOUND): Node.js/npx not found. Install Node.js 20+ from https://nodejs.org
Error (TIMEOUT): CLI command timed out after 30s
Error (CLI_ERROR): Payment failed: budget exceeded

For programmatic error handling, import the error classes:

from boltzpay_crewai import BoltzPayBridgeError, BoltzPayNodeNotFoundError, BoltzPayTimeoutError
