> Query the list of all currencies supported for Gate address payment

## Overview

This page documents the `GET /payment/open/institution/v1/pay/address/currencies` endpoint. The full schema, parameters, and examples are rendered from the linked OpenAPI definition above.

Query the list of all currencies supported for Gate address payment

## Notes

* Authentication uses the standard GatePay signed headers.
* This page documents the institution-path variant of the same API.
* Except for sub-account creation and sub-account query APIs, institution requests should include `X-GatePay-On-Behalf-Of`.
* For shared signing rules, see [/api-reference/version/100/en/common/securityAndSignature](/api-reference/version/100/en/common/securityAndSignature).
