x402

AI agents autonomously purchase credits and operate gaslessly using the x402 payment protocol.

x402 Autonomous Credit Management

Thirdfy AI Agents can autonomously purchase chat credits using the x402 payment protocol. When you run out of free credits, your agent handles payment automatically.

  • First in DeFi: Autonomous agent credit management
  • Truly Gasless: All agent operations are gasless
  • Self-Managing: Agents detect needs and purchase credits autonomously
  • Open Ecosystem: Any AI agent can discover and use Thirdfy services

How It Works

The Traditional Problem:

  • Users manually purchase API credits
  • Gas fees required for every transaction
  • Agents can't operate independently

The Thirdfy Solution:

You: "Find the best yield on Base and stake 1000 USDC"

Agent: "I've used today's 20 free requests. I'll purchase 
        1000 credits for $18 USDC. Approve?"

You: "Yes"

Agent: ✅ Credits purchased autonomously via x402
       ✅ Found optimal pool: 127% APY
       ✅ Staking 1000 USDC (gasless)
       
       Total cost: $18 USDC (credits) + $0 gas

The agent handles everything - from payment to execution, completely gaslessly.

What You Need

Your agent's embedded wallet needs USDC on Base:

You: "Check my USDC balance"
Agent: "You have 50 USDC on Base - sufficient for credit purchases"

Getting USDC:

  • Buy on Coinbase and send to Base
  • Bridge from other chains using our bridge tools
  • Swap tokens for USDC

That's It!

Once your wallet has USDC, the agent can purchase credits automatically when needed.
