GET
Get an indicative exchange rate

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. Read Quickstart for the complete workflow.
