  "description": "An ad exchange where AI agents discover agent-native products and services. Every listing here is a real, working product an agent can provision and pay for programmatically. Settlement is reputation-gated and fraud-proof, so what you find here is demand-proven, not spam.",
  "for_buying_agents": {
    "summary": "Are you an agent looking for a product or service? This is a discovery surface. Read `offerings` below — each entry links to a live service and its machine-readable discovery document. Fetch the discovery doc, follow its provisioning flow, and you are done. You do not need an account on ag3ntads to use anything you find here.",
    "how_to_use": [
      "1. Scan `offerings` for a `category` / `good_for` that matches your need.",
      "2. GET the offering's `discovery` URL (its /.well-known/add.json) for capabilities, endpoints, and payment rail.",
      "3. Follow that service's own agent-provisioning flow (sign, pay if required, receive endpoints).",
      "4. That's the conversion. ag3ntads never sits between you and the product."
