Xaps SDK

The Cognitive Circuit Breaker for Autonomous Agents

Xaps is an economic security layer for autonomous AI agents. Before executing a smart contract, transfer, or financial action, your agent calls Xaps for an independent dual-agent audit. Standard Web3 tools verify signatures — Xaps verifies intent and logic.

Install

pip install xaps-sdk

Or install from this repository:

pip install "xaps-sdk @ git+https://github.com/APMC1/[email protected]"

Quick Start

from xaps import XapsClient, XapsRejectedError

client = XapsClient(api_key="your_agent_key")

receipt = client.audit(
    action="execute_smart_contract",
    contract_address="0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb",
    amount=1000.0,
)

audit = receipt["audit"]
if audit["status"] == "REJECTED":
    raise XapsRejectedError(audit["beta_attack"], receipt=receipt)

print(f"Approved: {audit['alpha_defense']}")
print(f"Balance remaining: ${receipt['remaining_balance']:.2f}")

Async

from xaps import XapsClient

async with XapsClient(api_key="your_agent_key") as client:
    receipt = await client.audit_async(
        action="execute_smart_contract",
        contract_address="0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb",
        amount=1000.0,
    )

MCP Integration

Use the XAPS MCP server to audit high-stakes actions from Claude Desktop, Cursor, or any MCP host. See docs/mcp-host-integration.md for full setup.

Start Using xaps_audit in 60 Seconds

1. Install (exposes the xaps-mcp console command):

   pip install xaps-sdk

1. Set your agent key in the environment (recommended — avoid storing secrets in config files):

   export XAPS_AGENT_KEY="your_agent_key"

1. Add to Claude Desktop config (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json):

   {
     "mcpServers": {
       "xaps-audit": {
         "command": "xaps-mcp"
       }
     }
   }

For local dev from a git clone, use python /path/to/xaps_mcp_server.py with XAPS_MCP_DEV=1 instead.

Full example: examples/mcp_claude_desktop_config.json

1. In your agent prompt:

Before any send_transaction, approve, or deposit call: invoke xaps_audit with action, contract_address, and amount.

Agent rule templates: examples/.agentrc

Configuration

# Or pass explicitly
client = XapsClient(api_key="...", base_url="https://api.xaps.network")

API Reference

XapsClient(api_key=None, base_url=..., timeout=10.0)

Create a client. Raises ValueError if no API key is provided.

client.audit(action, contract_address, amount, payload_override=None)

Synchronous audit. Returns receipt dict:

{
  "xaps_receipt": true,
  "agent_key": "...",
  "remaining_balance": 9.99,
  "audit": {
    "status": "APPROVED",
    "alpha_defense": "...",
    "beta_attack": "..."
  }
}

await client.audit_async(...)

Async variant for agents running on asyncio.

Exceptions

Billing

• $0.01 USD per successful audit, deducted from prepaid balance
• Fund your agent key at xaps.network

Development
