# Get Delta

> Find out how much sovereignty moves, product by product.

See what sovereignty moves: its published scores, the same scores with every control engaged, and the distance between the two. In Claude.ai and supported clients you also get an interactive view.

It completes a set of three readings over one market. The [Capability Index](/mcp/tools/sovrnti_market_get_capaindex) ranks products by published Innovation with no control applied. [Sovrnti Max](/mcp/tools/sovrnti_market_get_sovrntimax) ranks them by the Innovation that survives with every control on. Delta is about the **movement between the two** — per product, on both axes, plus the straight-line distance.

The country matters as much here as it does for Sovrnti Max. It doesn't filter the list — it selects which **sovereign configuration** the `on` state is resolved under, so it decides what moves at all. The global view has no geography to resolve a configuration against, so nothing moves there.

## What you get

The same `MarketDualStateOutput` body Sovrnti Max returns — the two tools ask different questions of one query:

```json theme={null}
{
	"market": {
		"marketId": "mkt-collaboration",
		"name": "Collaboration & Productivity",
		"lastUpdated": "2026-06-25T05:55:47.051Z"
	},
	"products": [
		{
			"productId": "prod-microsoft-365",
			"name": "Microsoft 365",
			"scaleScore": 90.6,
			"off": { "i": 84.7, "c": 53.4 },
			"on": { "i": 76.2, "c": 53.3 },
			"delta": 8.5
		},
		...
	],
	"sovereignConfig": {
		"sovConfigId": "sovconfig-france",
		"name": "France Sovereign Configuration",
		"description": "..."
	},
	"countryFilter": "FR",
	"methodology": "..."
}
```

* `off` — the published scores, exactly what the Snapshot and the Capability Index report.
* `on` — the same scores re-resolved with every control of `sovereignConfig` engaged.
* `delta` — the straight-line distance between the two. **This is what Delta ranks and draws.**

Render it as a scatter of Innovation × Control with a line from each product's `off` position to its `on` position, or as a table of `off → on` per axis.

<Note>
  Delta reports the movement. It does not label products with a verdict, and neither should a
  summary built on it — what a Δ of 8.5 means depends on what you are buying, and the API does not
  know that.
</Note>

<Note>
  A product whose `on` equals its `off` — `delta: 0` — is one that **no control in this
  configuration touches**. That is a real result, not missing data. `sovereignConfig: null` means no
  configuration covers the requested country yet, so every Δ is 0; the market still exists and every
  product still renders.
</Note>

## Choosing a view

Delta has two visualizations over the same data, selected with the optional `view` parameter:

| `view` | Shows                                                                                                                                                                             |
| ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `map`  | **Default.** Innovation × Control, with a comet streak from each product's controls-off position to its controls-on one. Length is how far it moved; direction is what it traded. |
| `bars` | The controls-off ranking held still, each bar dropped to its controls-on height under a grey ceiling. The gap is what it gives up.                                                |

`view` is **presentational only**. Both views are always rendered, and the data returned is identical either way — a `map` request and a `bars` request are the same response. In an interactive client you can flip between them without another call.

## How to use it

Ask your assistant:

```text theme={null}
What does French sovereignty cost each collaboration product?
```

Or, to open on the ranking instead of the map:

```text theme={null}
Show me the collaboration market's sovereignty delta as bars.
```

Your assistant calls [List markets](/mcp/tools/sovrnti_markets_list) first if needed to confirm the market, then pulls the Delta.

## Troubleshooting

* **`market-not-found`** — the market name is well-formed but doesn't exist. Ask your assistant to list markets first.
* **`insufficient-credits`** — wallet empty. Top up in your organization's billing page.
* **Every product shows `delta: 0`** — not a bug. Either no sovereign configuration covers your country (check `sovereignConfig`), or no control in it affects these products.
* **The map shows one streak and a lot of still dots** — also not a bug. Only products a control actually moves grow a streak; today that is a small minority.
