```
rpc PreviewQuote(PreviewQuoteRequest) returns (QuotePreview)
```

Same pricing as [`GetQuote`](/api-reference/get-quote), minus the persistence. No quote hash is produced and nothing can be deposited against the result. Use it for the amount field of a swap form.

## Request

<ParamField body="src_chain" type="string" required>
  Source chain name, lowercase.
</ParamField>

<ParamField body="dst_chain" type="string" required>
  Destination chain name, lowercase.
</ParamField>

<ParamField body="src_token" type="string" required>
  Source token address.
</ParamField>

<ParamField body="dst_token" type="string" required>
  Destination token address.
</ParamField>

<ParamField body="trade_type" type="TradeType" required>
  Which side of the trade `amount` fixes and whether the output is guaranteed: `TRADE_TYPE_EXACT_INPUT`, `TRADE_TYPE_EXPECTED_OUTPUT`, `TRADE_TYPE_EXACT_INPUT_GUARANTEED_OUTPUT`, or `TRADE_TYPE_EXACT_OUTPUT`. `TRADE_TYPE_UNSPECIFIED` is rejected. See [Trade types](/concepts/trade-types).
</ParamField>

<ParamField body="amount" type="string" required>
  For exact input, the amount in the source token's base units. For expected output, the desired output in the destination token's base units.
</ParamField>

<ParamField body="gas_drop" type="string" required>
  Native asset to deliver on the destination, in base units. Empty string for none.
</ParamField>

<ParamField body="slippage_bps" type="uint32">
  Floor for the destination swap leg, in basis points.
</ParamField>

<ParamField body="src_slippage_bps" type="uint32">
  Floor for the source swap leg, in basis points.
</ParamField>

<ParamField body="referrers" type="Referrer[]">
  Referrer addresses and their basis points, so the preview matches what the quote will charge.
</ParamField>
There is no `recipient` or `refund_address`: nothing is bound.

## Response

<ResponseField name="amount_in" type="string">
  Input amount in the source token's base units. Echoes the request for exact input; the solved input for expected output.
</ResponseField>

<ResponseField name="amount_out" type="string">
  Expected output, net of every fee.
</ResponseField>

<ResponseField name="min_amount_out" type="string">
  Floor implied by the applied slippage.
</ResponseField>

<ResponseField name="slippage_bps" type="uint32">
  Slippage actually applied.
</ResponseField>

<ResponseField name="fee_breakdown" type="FeeBreakdown">
  Itemized costs, identical in shape to a quote's.
</ResponseField>

<ResponseField name="same_chain_swap" type="bool">
  True when the pair resolves to a same-chain swap rather than a bridge.
</ResponseField>

<ResponseField name="amount_in_usd_micros" type="string">
  Notional input value in USD micros. Optional.
</ResponseField>

<ResponseField name="amount_out_usd_micros" type="string">
  Notional output value in USD micros. Optional.
</ResponseField>

<ResponseField name="fulfill_eta_secs" type="uint64">
  Estimated seconds from deposit to fulfillment, the median over recent orders on the same chain pair and route type. Absent when there is no history and no configured default for the destination chain.
</ResponseField>

## Notes

Preview and quote use the same pipeline, so the numbers agree at the same instant. They diverge only as the market moves between the two calls, which is why a confirmation screen should show a freshly fetched quote rather than the last preview.

Errors are identical to [`GetQuote`](/api-reference/get-quote#errors).
