### Quoting a swap

`Quoter V2` returns the expected output for a given input without executing a trade. Use it from any EVM tooling pointed at Stable's RPC.

```bash theme={"dark"}
cast call 0xb070179E7032CdA868b53e6C1742F80c9e940d1A \
  "quoteExactInputSingle((address,address,uint256,uint24,uint160))(uint256,uint160,uint32,uint256)" \
  "(<TOKEN_IN>,<TOKEN_OUT>,<AMOUNT_IN>,<FEE>,0)" \
  --rpc-url https://rpc.stable.xyz
```

```text theme={"dark"}
(amountOut, sqrtPriceX96After, initializedTicksCrossed, gasEstimate)
```

Replace `<TOKEN_IN>`, `<TOKEN_OUT>`, `<AMOUNT_IN>`, and `<FEE>` (one of `100`, `500`, `3000`, `10000`) with the values for the pool you're quoting. For application integration, prefer the [Uniswap v3 SDK](https://docs.uniswap.org/sdk/v3/overview) or the [Universal Router](https://docs.uniswap.org/contracts/universal-router/overview) pointed at the addresses above.
