# POST /quote

> Get a fee estimate and expected output before the user confirms. AML/OFAC screening runs at this step.

`POST https://api.trustware.io/api/v1/routes/quote`

Returns a fee estimate, expected output amount, slippage, and estimated completion time for a proposed route. Call this before `POST /route` to show the user a confirmation screen. AML/OFAC screening runs synchronously. If the source or destination address is flagged, this call returns an error and no funds move.

## Request

```json theme={null}
{
  "fromChain": "43114",
  "toChain": "137",
  "fromToken": "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee",
  "toToken": "0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359",
  "fromAmount": "215124226346059100",
  "fromAddress": "0xeb212fe20f26243ec4d4df2dd49c8aa9fa75a201",
  "toAddress": "0xeb212fe20f26243ec4d4df2dd49c8aa9fa75a201",
  "slippage": 1
}
```

| Field | Required | Description |
| - | - | - |
| `fromChain` | Yes | Source chain ID as a string (e.g. `"43114"` for Avalanche). |
| `toChain` | Yes | Destination chain ID as a string (e.g. `"137"` for Polygon). |
| `fromToken` | Yes | Source token identifier: contract address on EVM, mint address on Solana, native denom on Cosmos. Use `"0xeeee...eeee"` for the native token on EVM chains. |
| `toToken` | Yes | Destination token identifier: contract address on EVM, mint address on Solana, native denom on Cosmos (e.g. `"unibi"`). |
| `fromAmount` | Yes | Amount in the smallest unit of the source token (wei for EVM). |
| `fromAddress` | Yes | Sender wallet address. AML screening runs against this address. |
| `toAddress` | Yes | Recipient wallet address. |
| `slippage` | No | Slippage tolerance as a percentage. Defaults to `1`. The accepted ceiling is provider dependent: some providers reject a route above `3`, others impose no limit, so a value above `3` can narrow which providers can serve the route. |

## AML behavior

If Trustware's AML/OFAC screening flags the source or destination address, this endpoint returns an error. No funds move. The specific reason is never exposed in the error response, so your application should handle the error generically and show a neutral message to the user.

<Warning>
  Always call `/quote` before `/route`. The AML check runs here. If you skip the quote step and call `/route` directly, you bear the risk of initiating a transaction that would have been rejected at the quote stage.
