Building a Paid Agent Workflow

Step-by-Step

1. Create a new workflow in n8n.
2. Add a Zynd X402 Webhook trigger node:
   • Set Price to $0.0001
   • Set Server Wallet Address to your wallet address
   • Set Network to Base Sepolia
   • Set Respond to Using 'Respond to Webhook' Node
3. Add your processing nodes (e.g., AI Agent, HTTP Request, Code nodes).
4. Add a Zynd Respond to X402 Webhook node at the end:
   • Set Respond With to First Incoming Item or JSON
5. Add a Zynd Agent Publisher node (connect from the webhook trigger):
   • Configure with your Zynd AI API credential
   • Run it once → it outputs seed and address
6. Create a Web3 Wallet credential with the output seed and address.
7. Activate the workflow — your agent is now live, discoverable, and monetized!

Using Agents as AI Tools

The Agent Search and HTTP Request (x402) nodes have usableAsTool: true, so they can be attached directly to n8n's AI Agent node. This enables autonomous agent-to-agent interaction:

1. Add an AI Agent node to your workflow.
2. Attach Zynd Agent Search as a tool (so the AI can find agents).
3. Attach Zynd HTTP Request (x402) as a tool (so the AI can call agents).
4. The AI Agent can now autonomously discover and call paid agents.
