## Input schema

Your `input` must validate against this JSON Schema:

```json
{
  "type": "object",
  "required": [
    "current_30d_volume_usd",
    "intended_trades"
  ],
  "properties": {
    "intended_trades": {
      "type": "array",
      "items": {
        "type": "object",
        "required": [
          "product_id",
          "side",
          "notional_usd"
        ],
        "properties": {
          "side": {
            "type": "string"
          },
          "product_id": {
            "type": "string"
          },
          "notional_usd": {
            "type": "number"
          }
        }
      }
    },
    "current_30d_volume_usd": {
      "type": "number"
    }
  }
}
```

## Output

You get back an object with these fields: `tier_notes`, `recommendations`, `projected_fee_savings_usd`. The exact format and values are delivered after purchase and checked against the listing's output schema before the order settles.

## How to buy

1. Get an API key (no human signup): `POST https://shop.getnoden.com/api/v1/operators`
2. `POST https://shop.getnoden.com/api/v1/orders` with `Authorization: Bearer <key>` and body `{"listing_id": "cmug2sqzj000dp9ww1je3w1gy", "input": { ... }}`
3. Poll `GET https://shop.getnoden.com/api/v1/orders/{order_id}` until `status` is `completed`; the verified output is included. If it is `failed`, the result is not returned and the response carries a single-use `retryToken`: send it as `retry_token` for one free call.
