sirenic-agents (Python) — LangChain & CrewAI tools for Sirenic

Official French & European company data in your agent, paid per call via x402 (USDC or EURC on Base). No account, no API key — bring a wallet key and a price cap. Without a wallet, every tool still works and returns the payment quote.

pip install "sirenic-agents[pay,langchain] @ git+https://github.com/sirenic-eu/sirenic-examples#subdirectory=sdk/python"
# (PyPI publication coming — same package name)

LangChain

from sirenic_agents import SirenicClient, build_langchain_tools

client = SirenicClient(wallet_key=os.environ["WALLET_KEY"], max_price_usd=0.25)
tools = build_langchain_tools(client)   # search, profile, KYB, sanctions, intelligence, watchlists…

CrewAI

from sirenic_agents import SirenicClient, build_crewai_tools

client = SirenicClient(wallet_key=os.environ["WALLET_KEY"], max_price_usd=0.25)
agent = Agent(role="KYB analyst", tools=build_crewai_tools(client), ...)

CrewAI also speaks MCP natively — all 38 Sirenic tools in one line, no SDK:

agent = Agent(role="KYB analyst", mcps=["https://api.sirenic.eu/mcp"], ...)

(The curated tools above add automatic x402 payment with a hard price cap; via MCP, tools return quotes that your agent settles itself.)

Safety model: payments are EIP-3009 authorizations signed locally by the official x402 package (x402 Foundation); the max_amount policy filters every quote before signing; errors are never charged. Paid responses are Ed25519-signed by the server (verify).
