arnaud-92/README.md

Hi, I'm Arnaud 👋

I'm the founder of MerchantStamp — we make e-commerce catalogs readable by AI shopping agents (ChatGPT, Claude, Gemini, Perplexity) through structured data, agent feeds, and protocol-level integrations.

What I work on

  • 🛍️ MerchantStamp — agent-readiness audit + enrichment for WooCommerce, Shopify, and beyond → https://merchantstamp.com
  • 🔌 Agentic commerce protocols — implementing a UCP merchant server for long-tail merchants
  • 📄 UCP mandate-evaluation lifecycle profile (com.merchantstamp.mandate-evaluation) — what happens when an AP2 mandate's TTL expires during checkout completion. Reuses the AP2/FIDO receipt construction. → Reference: https://merchantstamp.com/en/docs/protocols/ucp-mandate-evaluation → Discussion: ucp#512 · ucp#515

The agentic-commerce stack I think in: MCP (agent↔tool binding) · AP2/FIDO (cryptographic authority + receipts) · UCP (commerce lifecycle).
