# Get an indicative exchange rate

> Returns the current indicative all-in rate for an AUD and stablecoin pair. It is useful for estimates and display only.

## What this endpoint does

Returns the current indicative all-in rate for an AUD and stablecoin pair. It is useful for estimates and display only.

## When to use it

Call it before showing an estimate. Do not treat the response as a locked quote: direct payment routes price when funds arrive, while Treasury conversions use a conversion quote.

## Before you call

Authenticate with an API key that can read this resource. Results are restricted to the tenant account bound to that key.

## Money and balance effect

This is a read-only request. It does not reserve, debit, credit, or settle money.

## States and completion

A successful response is a point-in-time indication. It does not create an operation and has no settlement status.

## Safe retries

GET requests are read-only and may be retried with normal exponential backoff. Do not send an `Idempotency-Key`.
