Toolkit request: agentwallet-sdk
Composio has 500+ toolkits covering everything from CRMs to calendars to code execution — but there's nothing for payments. If an agent needs to pay for an API, handle usage-based billing, or move funds programmatically, devs have to wire up Stripe or crypto manually outside Composio.
What agentwallet-sdk does
agentwallet-sdk is an MIT-licensed, non-custodial wallet SDK built for AI agents. It uses the x402 protocol (HTTP 402 Payment Required) to handle agent-to-service payments, with spending limits enforced on-chain by smart contract.
- On-chain spend caps: limits set in a smart contract, not just config a dev can forget to update
- Non-custodial: agent holds its own keys — no intermediary custody
- ERC-6551 compatible: wallet tied to agent identity token
- Patent pending (v6.0.0)
The payment layer for this SDK also has an MCP server wrapper (agentpay-mcp) that was recently merged into NVIDIA's NeMo-Agent-Toolkit-Examples: NVIDIA/NeMo-Agent-Toolkit-Examples#17
What a Composio integration could look like
from composio_openai import ComposioToolSet, App
toolset = ComposioToolSet()
tools = toolset.get_tools(apps=[App.AGENTWALLET])
# Agent now has access to:
# - AGENTWALLET_PAY — make a payment to a service endpoint
# - AGENTWALLET_GET_BALANCE — check current wallet balance
# - AGENTWALLET_LIST_TRANSACTIONS — audit recent payments
# - AGENTWALLET_SET_SPEND_LIMIT — update on-chain spending cap
Why this fills a real gap
There are already Composio toolkit requests for financial data (TradeKix #2631) and document signing (Signbee #2932) — payments is the obvious missing piece. As agents start calling paid APIs and services, payment capability needs to be a first-class tool, not a manual integration.

Happy to assist with the toolkit implementation if the Composio team wants to move on this.
