# Overview

> The Orchestrations API provides a single interface for executing fiat and stablecoin conversions on the Paxos platform.

## Orchestration Rule

If the orchestration begins with a deposit from an external source, use an Orchestration Rule.

* Define orchestration behavior for incoming deposits.
* Automatically execute the specified conversion when a deposit matches a rule.
* Remain active and in effect until explicitly deleted.
* Each rule is associated with deposit instructions that must be used by the sender.

## Ad-Hoc Orchestrations

If the source funds are already on the Paxos platform (e.g., held in a profile), use the Create Orchestration endpoint to initiate a one-time conversion.

* This endpoint supports sending the converted funds to either another internal profile or an external destination.
* Rules are not required for ad-hoc orchestrations.

<Danger title="The Stablecoin Conversions API has been replaced">
  The [Orchestrations API](/api-reference/endpoints/orchestration/overview) replaces the Stablecoin Conversions API. New customers should use the Orchestrations API. Existing customers should follow the [migration guide](/api-reference/endpoints/stablecoin-conversion/overview#migration-guide).
