# POST /quote

> Preview an unstake's output amount and price impact before signing.

```http theme={null}
POST https://hubra.app/api/v1/quote
```

Preview the output of an **unstake** without committing. Use this to show price impact and output amount to a user before they sign anything.

Quotes are **non-binding**: pool state drifts between quote and unstake. Treat the returned `outAmount` and `priceImpactPct` as live estimates.

<Info>
  There is no quote endpoint for staking *into* a strategy. Stake quotes are deterministic: amount in equals amount out at the current receipt rate. Use [`GET /api/v1/strategies/{key}`](/developer/endpoints/get-strategy) to read the rate and compute locally.

## Response — `sol-native-stake` (instant)

```json theme={null}
{
  "strategy":       "sol-native-stake",
  "kind":           "instant",
  "inAsset":        "SOL",
  "outAsset":       "SOL",
  "inAmount":       "1.0",
  "outAmount":      "0.9952",
  "priceImpactPct": 0.0048
}
```

Same shape as liquid; the input "asset" is SOL because the active stake account is being settled to SOL via Sanctum's `depositStake`. `kind: "instant"` indicates this is a Sanctum-routed instant unstake quote (the only kind that can be quoted; `deactivate` does not have liquidity-based pricing).

## Response — `sol-leveraged-stake`

Previews burning raSOL Max LP back to raSOL. `amount` is the LP to burn; `path` is the redemption route the unstake would take.

```json theme={null}
{
  "strategy":  "sol-leveraged-stake",
  "inAsset":   "raSOL Max",
  "outAsset":  "raSOL",
  "inAmount":  "0.0195",
  "outAmount": "0.019485797",
  "path":      "flash-bracket",
  "kind":      "instant"
}
```

| Field       | Type                              | Description                                                     |
| ----------- | --------------------------------- | --------------------------------------------------------------- |
| `inAsset`   | `string`                          | `raSOL Max` (the LP being burned).                              |
| `outAsset`  | `string`                          | `raSOL` (the payout asset — the leveraged exit stops at raSOL). |
| `outAmount` | `string`                          | Estimated raSOL out at current NAV.                             |
| `path`      | `"vault-idle" \| "flash-bracket"` | Which redemption path the unstake would use.                    |

There is no leveraged **deposit** quote: the SOL → raSOL mint is a deterministic floor-division from the live pool snapshot, so there's nothing to preview. To estimate the SOL you'd ultimately receive (rather than raSOL), feed `outAmount` into a `sol-liquid-stake` quote.
