Hi, I'm Miguel Ángel 👋

Full Stack Developer · AI agents · x402 payments · Cali, Colombia 🇨🇴

I build software that AI agents can trust: APIs, automations and payment rails that only charge when the work is actually done.

X Portfolio LinkedIn Discord

🚀 Featured: PayBox Tribunal

If the API doesn't keep its promise, the agent doesn't pay.

Pay-on-validation for x402: the AI agent's payment is verified but only settled after the response is judged against the seller's published contract (schema → objective rules → AI judge). Built for the MoonPay PayBox hackathon.

  • ✅ Settled with real USDC on Solana mainnet and Base
  • 🛡️ 40 paid calls, 19 broken promises blocked, $0 charged for failures
  • 🧾 Promises written in plain language, compiled into deterministic / heuristic / probabilistic checks
  • 🔏 Every verdict signed with Ed25519 and verifiable offline
  • 🔌 MCP plugin for PayBox agents
