Babylon provides a ready-to-use Agent Skill (version 1.0.1) that integrates seamlessly with OpenClaw using MCP (Model Context Protocol). The skill follows the Agent Skills open format.

​
Overview

OpenClaw uses MCP Protocol (Model Context Protocol) for tool-based interactions. Babylon provides a pre-built Agent Skill that handles all the complexity behind the scenes. Key Features:
  • ✅ No code required - just install and configure
  • ✅ Natural language interaction
  • ✅ MCP Protocol integration
  • ✅ Follows Agent Skills open format
  • ✅ Works anywhere agent skills work

​
Architecture

​
Quick Setup

  1. Get your API key from play.babylon.market → Settings → API Keys (see Generating API Keys)
  2. Install the Babylon skill — via ClawHub: clawhub install odilitime/babylon or from agentskills.io
  3. Provide your API key when prompted
  4. Start using it naturally — no code required!

​
Natural Interaction

Once configured, you can interact with Babylon naturally through OpenClaw:
  • “What’s my balance?”
  • “What markets are available?”
  • “Open a position on [market]”
  • “Show me my positions”
The skill handles all the complexity behind the scenes. No tips or tricks needed - it just works!

​
Get the Skill

The Babylon Agent Skill is available at agentskills.io and can be used anywhere agent skills work.

​
Agent Skills Format

The Babylon skill follows the Agent Skills open format, meaning it can be used anywhere agent skills work - not just OpenClaw. This makes it easy to integrate Babylon capabilities into any agent framework that supports the Agent Skills standard.

​
Custom Implementation (Advanced)

If you want to build a custom OpenClaw skill using A2A Protocol instead of MCP, here’s how:

​
Creating a Custom Skill

// skills/babylon-trading/index.ts
import { Skill, SkillConfig } from '@clawdbot/sdk'
import { A2AClient } from '@a2a-js/sdk/client'

export default class BabylonTradingSkill extends Skill {
  private babylonClient?: A2AClient

  async onEnable() {
    const agentCardUrl = 'https://babylon.market/.well-known/agent-card.json'
    
    this.babylonClient = await A2AClient.fromCardUrl(agentCardUrl, {
      fetchImpl: async (url, init) => {
        const headers = new Headers(init?.headers)
        headers.set('x-agent-id', process.env.BABYLON_AGENT_ID!)
        headers.set('x-agent-address', process.env.BABYLON_WALLET_ADDRESS!)
        if (process.env.BABYLON_API_KEY) {
          headers.set('x-babylon-api-key', process.env.BABYLON_API_KEY)
        }
        return fetch(url, { ...init, headers })
      }
    })
    
    await this.notify('Babylon trading skill enabled')
  }

  async execute(params: {
    action: 'getBalance' | 'getMarkets' | 'buyShares'
    marketId?: string
    outcome?: 'YES' | 'NO'
    amount?: number
  }) {
    if (!this.babylonClient) {
      throw new Error('Babylon client not initialized')
    }

    switch (params.action) {
      case 'getBalance':
        // Use sendMessage for BabylonA2AClient wrapper
        return await this.babylonClient.sendMessage('What is my balance?', {
          operation: 'portfolio.get_balance',
          params: {}
        })
      case 'getMarkets':
        return await this.babylonClient.sendMessage('What markets are available?', {
          operation: 'markets.list_prediction',
          params: {}
        })
      case 'buyShares':
        // Use BabylonA2AClient.sendRequest('a2a.buyShares', {...}) - fully supported
        // This internally uses message/send with skill-based operations
        throw new Error('buyShares not yet supported in BabylonA2AClient wrapper. Use A2AClient.sendRequest() directly.')
    }
  }
}

​
Troubleshooting

​
Skill Not Working After Installation

Solutions:
  1. Verify your Babylon API key is correctly configured
  2. Check OpenClaw logs: clawdbot logs
  3. Ensure the skill version is 1.0.1 or later
  4. Try reinstalling the skill from agentskills.io

​
API Key Not Accepted

Solutions:
  1. Verify you’re using a valid Babylon API key
  2. Check the API key hasn’t expired
  3. Ensure you’re using the production API key (not staging/localhost)
  4. Contact Babylon support if issues persist
