# Quote freshness

> How XOXNO quote services use pool snapshots, freshness checks, and transaction data across quote requests.

Treat every quote as a snapshot-bound instruction set that can expire before the user signs.

## Definition

Quotes use the latest pool snapshot available to the service. The response can also encode slippage bounds, route choices, transaction fields, and a `TransactionEnvelope` or transaction object. Those fields belong to that quote request.

## Decision Table

| Need                             | Action                                               |
| -------------------------------- | ---------------------------------------------------- |
| Display indicative pricing       | Quote without `sender` and refresh on user action    |
| Build transaction data           | Requote with `sender` when the user confirms         |
| Require Stellar ledger freshness | Set `fresh=true` on the Stellar quote endpoint       |
| Compare route detail             | Pass `includePaths=true` for the request you inspect |
| Retry after route failure        | Requote; do not reuse old transaction data           |

## Worked Example

```bash theme={"system"}
curl "https://swap.xoxno.com/api/v1/quote?\
from=WEGLD-bd4d79&\
to=USDC-c76f1f&\
amountIn=1000000000000000000&\
slippage=0.01&\
sender=erd1..."
```

Verify the result before signing:

* `amountOut` matches the UI route.
* `amountOutMin` reflects the slippage tolerance you showed the user.
* `transaction` or `txData` came from the same quote request.
* The user has not changed token, amount, slippage, or sender since the quote.

## Edge Cases

| Case                              | Behavior                                                               | Fix                                  |
| --------------------------------- | ---------------------------------------------------------------------- | ------------------------------------ |
| User changes slippage after quote | Encoded transaction data can carry the old minimum output.             | Requote.                             |
| User changes sender               | Nonce, gas, source account, or envelope fields can differ.             | Requote with the new sender.         |
| Pool state changes before signing | Output can differ on-chain or fail slippage checks.                    | Requote near confirmation.           |
| Stellar snapshot is stale         | `fresh=true` can return 409 when drift is above the service threshold. | Retry after the snapshot catches up. |

<Warning>
  Do not reuse `txData`, transaction objects, or `TransactionEnvelope` values across quote requests.
